60 Series 9 & 10 Exam Concepts You Need to Know Before Test Day
I have sat with too many candidates who knew the rules cold but still missed the questions that turned on a supervisory judgment call or a timing trigger. This guide drills the hinge facts: which approvals happen before the trade, which filings have hard deadlines, and where the exam tries to trip you between two similar-sounding rules.
How to Use These 60 Concepts
Do not read this as a list of facts to underline. For each concept, make sure you can explain the rule in your own words, spot the hinge fact in a scenario, and say why the tempting answer is wrong. The exam angle identifies the decision point. The memory hookgives you a compact way to retrieve it when the clock is running.

Series 10: Supervise Associated Persons and Personnel Management
Series 9 & 10 concept 1 of 60
Statutory Disqualification and the Pre-Hire Investigation Gatekeeping Decision
Statutory disqualification is defined in Exchange Act Section 3(a)(39) and covers specific adverse events: a conviction within the past ten years for certain securities or fraud crimes, securities-related injunctions, SEC disciplinary orders, and expulsions or bars from association imposed by an SRO. Before filing a Form U4, the firm must investigate the applicant's background through CRD and other reasonable means. If the applicant is statutorily disqualified, the firm cannot simply proceed with registration. Association requires relief: FINRA eligibility proceedings or an SEC application under Rule 19h-1. MSRB Rule G-4 applies the same gate to municipal securities dealers. The supervisory decision point is identifying the disqualifying event before the hire, not after the U4 is filed.
Exam angle
The hinge is the ten-year lookback for convictions versus no time limit on expulsions, bars, and injunctions. A firm that associates a statutorily disqualified person without seeking relief has a registration problem, and the answer turns on which event triggered the disqualification.
Memory hook:Convictions expire after ten years; bars and injunctions never do.
Series 9 & 10 concept 2 of 60
Form U4 and U5 Mechanics: Termination Notices, Amendments, and 30-Day Windows
Form U4 registers a person; Form U5 ends the registration. When an associated person leaves, the firm files a U5 within 30 days stating the reasons for termination, and must promptly send a copy to the former employee, who can dispute the language through FINRA's arbitration process. Amendments work the same way: when the firm learns of a material fact requiring disclosure on a U4 or U5, it files the amendment within 30 days of learning the fact, not within 30 days of the underlying event. The former employee must also receive a copy of any U5 amendment. Supervisors should treat the 30-day clock as running from discovery, which is the detail most firms miss.
Exam angle
The clock runs from when the firm learns the fact, not when the event occurred. Distinguish the filing deadline from the copy obligation to the former employee, and remember the employee's remedy for disputing disclosure language is arbitration.
Memory hook:U4 hires, U5 fires; 30 days from the day you learn it.
Series 9 & 10 concept 3 of 60
Fingerprinting Requirements Under Exchange Act Rule 17f-2 and the Limited Exceptions
Exchange Act Rule 17f-2 requires broker-dealers to fingerprint partners, officers, directors, and employees engaged in the securities business, and to submit the cards to the FBI through CRD. The fingerprints let regulators catch undisclosed criminal history. The main exception covers people whose functions are solely and exclusively clerical or ministerial and who have no access to securities or funds, such as a mailroom worker with no access to money or certificates. Note the word solely: a person who handles customer funds or securities even occasionally is not excepted. Transfer agents face parallel requirements. If an employee refuses to be fingerprinted, the firm cannot permit them to remain in a covered position.
Exam angle
The exception is narrow: solely clerical or ministerial duties plus no access to funds or securities. Any incidental access to money or certificates kills the exception, and refusal to be fingerprinted means the person cannot stay in a covered role.
Memory hook:Fingerprint the securities business; exempt only the purely clerical with zero access.
Series 9 & 10 concept 4 of 60
Outside Business Activities (FINRA 3270): Prior Written Notice and the Supervisory Response Triggers
Rule 3270 requires a registered person to provide written notice to the member before engaging in any outside business activity, including secondary employment or serving as an officer or director. Notice is not approval. Once notified, the firm can allow the activity, impose conditions or restrictions, or prohibit it outright. Two triggers matter for supervisors. First, if the firm determines the activity is actually a securities business, it must either supervise the activity as its own or the person cannot conduct it. Second, if the member begins compensating the person for the activity, it is no longer outside business at all; it becomes the firm's business and must be supervised accordingly. Failure to notify is itself a violation even when the activity is benign.
Exam angle
The hinge is prior written notice, and the trap is assuming notice equals permission. Watch the two conversions: a securities business must be supervised or stopped, and member compensation turns an outside activity into an inside one.
Memory hook:Notice first, approval never; firm pay makes it inside business.
Series 9 & 10 concept 5 of 60
Private Securities Transactions (FINRA 3280): Selling Away, Compensation, and the Written-Notice Distinction
Rule 3280 governs selling away: an associated person participating in a private securities transaction away from the firm must give prior written notice describing the security, the person's role, and whether compensation is expected, including trailing commissions. If the person will receive selling compensation, the firm must treat the transaction as if it were its own: supervise it, apply recordkeeping rules, and hold the person to the firm's compensation requirements. If the person receives no compensation, the firm can still restrict or prohibit the transaction. Notice does not equal approval, and the firm can deny the activity even when the notice is complete. The supervisor's job is to evaluate the notice and decide, not just file it.
Exam angle
The pivot is selling compensation, including trailing commissions, which forces the firm to treat the transaction as its own. Uncompensated participation still requires notice, and notice never equals approval.
Memory hook:Selling away: notice first; selling pay makes it the firm's trade.
Series 9 & 10 concept 6 of 60
Associated Persons' Accounts at Other Firms (FINRA 3210): Notice and Duplicate Statement Requirements
Rule 3210 requires an associated person to give written notice to their firm before opening an account at another broker-dealer or financial institution; the firm may object and deny the request. If the other firm is a FINRA member, the person must also tell that firm they are an associated person of a member. The employer's key supervisory tool is the duplicate statement request: the firm can require the person to ask the other firm to send duplicate confirmations and statements directly to the employer, letting supervisors monitor for front running, churning, or prohibited trading. Notice must come before the account is opened, and the firm can condition approval on receiving the duplicates.
Exam angle
Notice is required before opening, not after, and the firm may object outright. The monitoring mechanism is duplicate statements and confirmations, which the employer can compel the employee to request from the other firm.
Memory hook:Notice before opening; duplicates let the boss watch your other account.
Series 9 & 10 concept 7 of 60
Gifts, Gratuities, and Noncash Compensation: FINRA 3220 and MSRB G-20 Limits and Vendor Compensation
FINRA Rule 3220 caps gifts and gratuities to or from people at other firms at $100 per person per year. Business entertainment is not a gift if it is ordinary and reasonable and not conditioned on sales, so a working lunch is fine while season tickets tied to production are not. MSRB G-20 applies the same $100 annual limit for municipal business and adds rules on noncash compensation such as meals, travel, and event tickets connected to municipal securities activities. Compensation from third-party vendors, like product sponsors paying reps, is also noncash compensation the supervisor must police. The decision rule: identify the value, aggregate gifts from the same giver, and compare against the limit.
Exam angle
Aggregate gifts from the same source per year before comparing to the $100 limit. Entertainment is excluded only if ordinary, reasonable, and not tied to business; anything conditioned on production counts as a gift.
Memory hook:One hundred dollars per person per year; entertainment must be earned, not bought.
Series 9 & 10 concept 8 of 60
Branch Office Inspections: OSJ Annual Cycles, Non-OSJ Intervals, and Coverage Gaps from Resignations
Under Rule 3110.12, a qualified principal must inspect each office of supervisory jurisdiction at least annually and every non-OSJ branch office at least once every three years. The limited exception: an office of one or two registered persons who conduct no business with the public and accept no customer funds may be inspected on a periodic schedule the firm establishes. Resignations create the practical trap. When a branch's only supervisor departs, the firm must promptly reassign supervisory responsibility to another qualified principal; until coverage exists, the office cannot conduct business that requires supervision. Supervisors should track inspection dates and coverage assignments together, because a lapse in either is a supervisory system failure.
Exam angle
OSJ annually, non-OSJ every three years, with the narrow exception for one-to-two person offices doing no public business. On resignations, the answer is prompt reassignment of a qualified principal, not a waiting period.
Memory hook:OSJ yearly, branches every three; a resigning supervisor needs a same-day replacement.
Series 10: Supervise the Opening and Maintenance of Customer Accounts
Series 9 & 10 concept 9 of 60
Regulation Best Interest vs. FINRA 2111 Suitability: Four Obligations and the Three Suitability Components
Regulation Best Interest applies when a broker-dealer recommends a securities transaction or strategy to a retail customer, and it imposes four obligations: disclosure, care, conflict of interest, and compliance. The care obligation folds in the diligence of FINRA's suitability rule. Rule 2111 has three components: reasonable-basis suitability (the product fits someone), customer-specific suitability (it fits this customer), and quantitative suitability (the trading pattern, including churning, fits no one). Reg BI has no separate quantitative prong, but excessive trading still violates the care obligation. Know Your Customer under Rule 2090 is a separate duty to know essential facts and applies even without a recommendation. Supervisors should map each concern to the right framework before acting.
Exam angle
Match the fact pattern to the framework: four Reg BI obligations for retail recommendations, three suitability components under 2111, and KYC as a separate duty requiring no recommendation. Quantitative suitability is the 2111-only label.
Memory hook:Reg BI: disclose, care, conflicts, comply. Suitability: reasonable, customer, quantitative.
Series 9 & 10 concept 10 of 60
Customer Identification Program Under USA PATRIOT Act Section 326: Verification, Records, and List Screening
USA PATRIOT Act Section 326 requires every broker-dealer to run a customer identification program. Before or within a reasonable time after opening an account, the firm must collect the customer's name, date of birth, address, and an identification number, such as a taxpayer ID or, for a foreign person, a passport number with country of issuance. The firm must verify that identity within a reasonable time using documents or nondocumentary methods. Records of the identifying information must be kept five years after the account closes, and the firm must check government lists, such as terrorist lists, within a reasonable time after opening. Existing customers and certain accounts, like those of other financial institutions, are excluded.
Exam angle
The four data elements, the five-year retention after account closure, and the reasonable-time window for verification and list checks are the tested facts. Foreign persons use a passport number, not a taxpayer ID.
Memory hook:Name, birth date, address, ID number; keep records five years after the account dies.
Series 9 & 10 concept 11 of 60
AML Program Supervision (FINRA 3310): Red Flags, SAR Filing Triggers, and OFAC Screening on Disbursements
FINRA Rule 3310 requires each firm to maintain a written AML program reasonably designed to achieve compliance: approved by senior management, independently tested at least annually, headed by a designated AML compliance officer, and supported by ongoing employee training. Supervisors act on red flags such as structuring cash deposits, unusual third-party wires, and rapid in-and-out movement of funds. When suspicious activity is detected, the firm files a SAR with FinCEN within 30 days, extendable another 30 if no suspect has been identified; there is no dollar minimum, and the customer must never be told. OFAC screening applies to disbursements with no de minimis threshold, and blocked transactions are reported to OFAC.
Exam angle
SAR timing is 30 days from detection, plus 30 more only if no suspect is identified, and SAR confidentiality forbids tipping the customer. OFAC has no minimum amount and blocks transactions outright.
Memory hook:Thirty days to a SAR, never tell the customer, and OFAC blocks at any dollar.
Series 9 & 10 concept 12 of 60
Discretionary Account Supervision (FINRA 3260): Written Authority, Principal Acceptance, and Time-and-Price Exceptions
Under Rule 3260, an account is discretionary when the rep chooses both what to trade and whether to trade. The firm needs written authority signed by the customer and written acceptance by a principal before discretionary trading begins, plus ongoing principal review. The exception in 3260(d) covers time-and-price discretion: the customer can authorize the rep to choose the price and timing for a specific order, but that authority dies at the end of the business day unless the customer gives written authorization that lasts longer. Discretion over what to buy or sell never fits the exception. A rep who exercises discretion without the paperwork has made an unauthorized trade, and the supervisor must catch it in review.
Exam angle
The hinge is the scope of the authority: full discretion needs written customer authority plus written principal acceptance, while time-and-price discretion expires at the end of the business day unless extended in writing.
Memory hook:Full discretion: signed by customer, accepted by principal; time-and-price dies at the closing bell.
Series 9 & 10 concept 13 of 60
Day-Trading Account Approval (FINRA 2130) and the Rule 2270 Risk Disclosure Requirement
Rule 2130 requires a firm to have reasonable procedures for approving day-trading accounts. Before the account can day trade, a designated supervisor must approve it based on essential facts: the customer's financial situation, investment experience, and risk tolerance. Rule 2270 adds a mandatory step: the firm must deliver the day-trading risk disclosure statement and obtain the customer's signed acknowledgment before approval is granted. Both pieces are supervisory checkpoints, and the sequence matters: disclosure and acknowledgment come before approval, which comes before the first day trade. A customer who meets the pattern day trader equity rules but was never approved still leaves the firm exposed, because approval is a separate requirement from funding.
Exam angle
Approval under 2130 and the signed risk disclosure under 2270 are separate requirements, and the disclosure must be delivered and acknowledged before approval. Funding the account does not satisfy either step.
Memory hook:Disclose, sign, approve, then trade; money alone never opens a day-trading door.
Series 9 & 10 concept 14 of 60
ACATS Transfers (FINRA 11870): Timeline Mechanics and the Rule 2140 Bar on Interference
ACATS under Rule 11870 standardizes account transfers. The customer authorizes the transfer with a signed instruction to the receiving firm. The receiving firm must submit transfer instructions to the carrying firm within one business day of the customer's authorization; the carrying firm must validate or take exception within one business day; and the transfer must be completed within three business days after validation. Assets move in bulk, and the carrying firm cannot cherry-pick what to send. Rule 2140 closes the loophole: in employment disputes, a firm cannot use litigation or threats to delay or block a departing rep's customers from transferring, though it may pursue its claims separately in arbitration.
Exam angle
Track the business-day clocks: one day to submit, one day to validate, three days to complete after validation. Rule 2140 bars interference in employment disputes regardless of the firm's grievances.
Memory hook:Submit in one, validate in one, complete in three; never block a transfer over a grudge.
Series 9 & 10 concept 15 of 60
Regulation T and Margin Call Mechanics: SMA, Payment Deadlines, and Extension-of-Time Logic
Regulation T sets initial margin at 50% for purchases of margin-eligible securities, and the customer must pay the debit within five business days of the trade date unless the firm obtains an extension from its designated examining authority, which for most firms is FINRA. The request must be filed before the deadline. The special memorandum account, or SMA, works as a line of credit: it increases with cash deposits, sale proceeds, dividends, and paydowns of the debit, but never with market appreciation. A customer can spend SMA to buy additional securities without triggering a new Reg T call. Supervisors watch for aged calls, late extension requests, and misuse of SMA to mask unmet debits.
Exam angle
SMA never grows from appreciation, only from cash, proceeds, dividends, and debit paydowns. Extensions must be requested before the fifth business day, and the DTA is FINRA for most firms.
Memory hook:Pay in five or beg FINRA first; SMA rises with cash, never with the market.
Series 9 & 10 concept 16 of 60
Pattern Day Trader Requirements: $25,000 Minimum Equity and Four-to-One Day-Trading Buying Power
A pattern day trader is a margin customer who executes four or more day trades within five business days, provided those day trades exceed six percent of the customer's total trades in that window. Once the pattern is met, the account needs at least $25,000 in equity on the day trading occurs. The reward is day-trading buying power of four times maintenance excess, double the two-to-one overnight buying power. If equity falls below $25,000, the firm issues a margin call with five business days to cure; failure means the account is restricted to the two-to-one level for 90 days. The six percent test keeps small, infrequent traders out of the pattern.
Exam angle
The pattern needs both tests: four day trades in five business days and more than six percent of total trades. Equity below $25,000 triggers a five-day cure before the 90-day restriction to two-to-one.
Memory hook:Four trades in five days over six percent; twenty-five thousand buys four-to-one power.
Series 9 & 10 concept 17 of 60
Portfolio Margining Eligibility and the Contrast with Strategy-Based Margin
Portfolio margining replaces fixed, strategy-based percentages with a stress test: the margin equals the theoretical worst-case loss on the portfolio under specified market moves, with larger shocks for concentrated positions. Because hedged positions offset, a long stock position paired with a protective put requires far less margin than strategy-based rules would demand. Eligibility requires a margin account with minimum equity of $100,000 under FINRA Rule 4210, though firms may set higher thresholds, and the customer must understand the risks. Retirement accounts like IRAs are generally not eligible. Supervisors should confirm eligibility documentation before permitting portfolio margin and watch concentrated positions, which can push requirements above strategy-based levels.
Exam angle
The hinge facts are the $100,000 minimum equity, the stress-based calculation that rewards hedging, and the concentration penalty. Compare against strategy-based fixed percentages, and remember IRAs are generally excluded.
Memory hook:Portfolio margin: one hundred thousand in, stress-tested, hedges offset, concentration bites.
Series 9 & 10 concept 18 of 60
Hypothecation and Possession-or-Control: Rule 15c3-3, the 140% Margin Rule, and Excess Net Capital
Hypothecation means pledging customer securities as collateral. Under Exchange Act Rule 15c2-1, the customer must consent in writing before the firm hypothecates or rehypothecates their securities. Rule 15c3-3 adds the possession-or-control requirement: a broker-dealer may rehypothecate customer margin securities up to 140 percent of the customer's debit balance, but any excess must be segregated in possession or control. If the firm fails the possession-or-control test, the shortfall flows into the weekly reserve formula computation, forcing a deposit to the special reserve bank account. The 140 percent cushion exists because rehypothecated collateral supports the debit plus the estimated costs of liquidation. Supervisors reconcile daily and compute the reserve weekly.
Exam angle
The number is 140 percent of the debit balance; anything above it must be held in possession or control. A possession-or-control failure feeds the weekly reserve computation, not a customer margin call.
Memory hook:Rehypothecate to 140 percent of the debit; the excess sits segregated or the reserve pays.
Series 9 & 10 concept 19 of 60
Account Maintenance Red Flags: Foreign Address Changes, P.O. Box Requests, and Suspicious Powers of Attorney
Certain maintenance requests are classic red flags. A change to a foreign address followed shortly by a wire transfer request can signal an account takeover. A request to route statements to a P.O. box, especially paired with instructions to stop calling, hides activity from the customer's view. A newly executed power of attorney on an elderly customer's account, followed by withdrawals benefiting the attorney-in-fact, suggests exploitation. Third-party checks and disbursements to unrelated parties raise similar concerns. The supervisory response is consistent: verify independently using a phone number on file, delay the disbursement, escalate to compliance, and consider a SAR if the facts support suspicion. Convenience is never a reason to skip verification.
Exam angle
The trap is treating these as routine service requests. The correct answer pairs the red flag with independent verification and a delay or escalation, not with honoring the written instruction at face value.
Memory hook:Foreign moves, P.O. boxes, fresh POAs: verify by known number, delay the money.
Series 9 & 10 concept 20 of 60
Regulation S-P Privacy Obligations: Initial and Annual Notices, Opt-Out Rights, and Safeguarding Standards
Regulation S-P governs privacy of customer financial information. The firm must deliver an initial privacy notice when the customer relationship begins and an annual notice each year after, describing the categories of information collected and shared. Customers get a reasonable opportunity to opt out before the firm shares nonpublic personal information with nonaffiliated third parties for marketing. Exceptions exist for processing and servicing transactions, legal or regulatory purposes, and joint arrangements, and no opt-out is required for those. The rule also requires a written safeguards program with administrative, technical, and physical protections sized to the firm's operations. Supervisors should confirm notices are delivered on schedule and that actual sharing practices match the disclosures sent to customers.
Exam angle
Separate the two notices: initial at the start of the relationship and annual thereafter. Opt-out applies only to nonaffiliated third parties for marketing; servicing and legal exceptions need no opt-out.
Memory hook:Notice at opening, notice every year; opt-out for marketing, never for servicing.
Series 9 & 10 concept 21 of 60
Confirmations and Statements: Rule 10b-10, FINRA 2232, Quarterly Statements, and Mail-Hold Limits (FINRA 3150)
Rule 10b-10 and FINRA Rule 2232 work together on confirmations. The SEC rule requires a broker to deliver a confirmation at or before completion of the transaction, meaning by settlement date rather than trade date, disclosing capacity as agent or principal, price, commission, and other required items. Account statements go out at least quarterly under FINRA 2231. FINRA 3150 governs mail holds: the firm needs the customer's written request, statements and confirmations may not be held longer than two months, and other mail no longer than six months, with an exception for customers who receive mail at a post office box or similar address. Supervisors treat mail holds as an elder-exploitation red flag because suppressed statements can hide unauthorized activity.
Exam angle
The hinge facts are timing and limits: confirmations are due at or before completion, meaning settlement, statements are quarterly, and mail holds cap at two months for statements and confirmations and six months for other mail, absent the PO Box exception.
Memory hook:Confirm by settlement, statements quarterly, mail holds two months and six, PO Box exception.
Series 9 & 10 concept 22 of 60
Cost Basis Reporting and Transfer Mechanics: DVP/RVP, Journals, and Physical Stock Handling
Cost basis reporting obligates brokers to track and report adjusted basis and holding period on Form 1099-B for covered securities, and basis travels with the account through ACATS transfers. DVP/RVP means delivery versus payment and receive versus payment: securities move only against money, eliminating principal risk at settlement. A journal moves assets between accounts at the same firm, so a journal to a third party is a classic money-laundering red flag demanding heightened review. Physical certificates require an endorsed assignment or power of substitution with a medallion signature guarantee under FINRA 11550, and supervisors should scrutinize third-party certificates before accepting them for deposit.
Exam angle
Know the mechanism each term describes: DVP/RVP is a settlement-risk control, journals are internal moves that become AML flags when third parties appear, and physical stock needs a medallion-guaranteed endorsement. Match the term to the risk.
Memory hook:DVP pairs paper with payment; journals stay in-house; certificates ride only with a medallion.
Series 9 & 10 concept 23 of 60
Rule 144 Restricted Securities: Holding Periods, Volume Limitations, and Legend Removal Decisions
Rule 144 governs resales of restricted securities acquired in unregistered, private transactions. The holding period is six months before any public resale. Affiliates remain subject to the full rule after six months: volume limits of the greater of one percent of shares outstanding or the average weekly trading volume over the prior four weeks, manner-of-sale conditions, and Form 144 filing when sales exceed thresholds. Non-affiliates who have not been affiliates within the prior three months face no Rule 144 limits after the six-month period. Legend removal is a legal decision: the supervisor needs evidence the exemption is satisfied, typically an opinion of counsel, before the legend comes off.
Exam angle
The hinge is affiliate status and the six-month clock: affiliates never escape volume limits and Form 144, while non-affiliates sell freely after six months. The greater of one percent or average weekly volume sets the cap.
Memory hook:Six months to sell; affiliates stay chained to volume limits forever; legends die only with counsel's blessing.

Customer Complaint Handling: FINRA 4513 Recordkeeping, 4530 Reporting Thresholds, and 3110(b)(5) Review Duties
FINRA 4513 requires a record of every written customer complaint, including the complainant's identifying details and a summary of any action taken, retained under the books-and-records schedule. FINRA 4530 drives regulatory reporting: complaints alleging theft, forgery, misappropriation, or check kiting must be reported within 30 calendar days, and firms file a quarterly statistical summary of complaints not otherwise reportable. Rule 3110(b)(5) closes the loop: a registered principal must review complaints to detect patterns and trends and report them to the appropriate supervisor. The word written matters; a verbal gripe is not a 4513 record, though smart firms document it anyway.
Exam angle
Separate the three duties: 4513 is recordkeeping, 4530 is regulatory reporting on a 30-day and quarterly cadence, and 3110(b)(5) is the principal's pattern review. A complaint that is only verbal triggers none of them automatically.
Memory hook:4513 records it, 4530 reports it, 3110(b)(5) reviews it for patterns.
Series 9 & 10 concept 25 of 60
Trade Error Correction: Cancel-and-Rebill Justification, Error Accounts, and Rule 11890 Clearly Erroneous Standards
Cancel-and-rebill exists to fix genuine errors, and the supervisor's job is proving the error was genuine. Every cancel and rebill needs documented justification and principal approval before processing. The trap is selective generosity: adjusting errors only in the customer's favor, or using cancels and rebills to give favored customers better prices, violates fair dealing standards. Error accounts absorb the firm's losses so customers are made whole. FINRA 11890 is a different animal entirely: it governs clearly erroneous transactions on exchanges, where the exchange applies objective price-deviation criteria and decides whether to bust the trade. The firm cannot unilaterally cancel an executed exchange trade just because it dislikes the fill.
Exam angle
Distinguish internal error correction from exchange busts: cancel-and-rebill needs documented principal approval and a real error, while 11890 lets only the exchange nullify a clearly erroneous execution based on price deviation.
Memory hook:Document the error, principal approves, the exchange alone busts 11890 trades.
Series 9 & 10 concept 26 of 60
Unauthorized Trades and Unapproved Discretion: Detection, Correction, and the Line Between the Two
An unauthorized trade means the customer never consented at all: no order, no instruction, nothing. Unapproved discretion is different: the customer wanted to trade, but the rep chose which security or whether to trade, exercising discretion without written discretionary authority. FINRA 3260 requires written customer authorization plus firm acceptance before an account can be handled with discretion; the exception is time-and-price discretion, where the rep picks timing and price on an unsolicited order without any writing. For unauthorized trades, the customer may ratify or demand cancellation, and the firm must make the customer whole. Supervisors detect both by matching trades in unsolicited accounts against records of actual customer instructions.
Exam angle
The line turns on consent and scope: no consent equals unauthorized; consent to trade but rep-chosen security equals unapproved discretion. Time-and-price discretion alone needs no written authorization under 3260.
Memory hook:No consent, unauthorized; rep picks the what, discretion; time and price needs no paperwork.
Series 9 & 10 concept 27 of 60
Regulation SHO: Locate Requirements, Close-Out Deadlines, Threshold Securities, and the Bona-Fide Purchase Test
Regulation SHO attacks abusive short selling with three mechanisms. First, the locate requirement: before accepting a short sale, the firm must document that it borrowed the security or has a reasonable basis to believe it can be borrowed. Second, threshold securities: stocks with persistent fails-to-deliver land on the threshold list, and once listed, the firm cannot short them without a pre-borrow and must close out existing fails within the rule's specified windows. Third, the bona-fide purchase test: a close-out requires an actual purchase that results in delivery. Sham buy-ins and paper transactions do not satisfy the obligation. Supervisors review locate documentation, fail reports, and the threshold list daily.
Exam angle
Hinge facts: locate documentation must exist at order entry, threshold-list stocks demand pre-borrowing and close-out of fails, and only a purchase actually resulting in delivery counts as bona fide.
Memory hook:Locate before you short; persistent fails make the threshold; only real delivery closes out.
Series 9 & 10 concept 28 of 60
Trading-Ahead Violations: FINRA 5270 Front Running, 5280 Research Reports, and 5320 Customer Limit Orders
Three rules, one principle: the customer's order or the firm's own report comes first. FINRA 5270 prohibits trading ahead of a customer's block transaction when the firm knows the order is coming; the firm cannot position its book to profit from the market impact. FINRA 5280 prohibits trading ahead of the firm's own research report, buying or selling before publication while the market is unaware of the rating change. FINRA 5320 prohibits the firm from trading its own account at a price that would satisfy a customer's executable limit order unless it executes the customer's order first. Every violation turns on firm knowledge of the pending order, report, or limit.
Exam angle
Match the rule to the victim: 5270 protects the block order, 5280 protects the research report's readers, 5320 protects the resting limit order. Firm knowledge of the pending item is the common element.
Memory hook:5270 blocks front-running blocks, 5280 guards research, 5320 honors limit orders.
Series 9 & 10 concept 29 of 60
Best Execution (FINRA 5310): Regular and Rigorous Review, Interpositioning, and Rule 606 Routing Disclosures
FINRA 5310 requires reasonable diligence to ascertain the best market and execute so the customer's price is as favorable as possible under prevailing conditions. The rule also demands regular and rigorous reviews of the quality of the firm's executions, comparing venues and looking for systematic underperformance. Interpositioning, inserting a third party between the customer and the best available market, is prohibited unless it is consistent with best execution. Rule 606 is the disclosure side: firms must prepare and make public, quarterly, a report describing order routing, including venues used and payment for order flow received. Supervisors should be able to show the review actually happens, not just that a policy exists.
Exam angle
Best execution is a process, not a one-time check: the answer changes when a question asks about regular and rigorous execution reviews, interpositioning's narrow exception, or Rule 606's quarterly public routing report.
Memory hook:5310 executes best and reviews rigorously; 606 tells the public where orders went.

Markup and Commission Supervision (FINRA 2121): Riskless Principal Markups, the 5% Policy Framework, and Concurrent Trades
FINRA 2121 requires fair prices and commissions. For riskless principal trades, where the firm buys to cover a customer sale it already has in hand, the markup is measured from the prevailing market price at the time of the customer transaction, not from the firm's own cost. The 5% policy is a guideline, not a safe harbor: regulators weigh the type of security, its availability, price, size of the transaction, and disclosure to the customer. Concurrent trades deserve special attention: when the firm buys and sells the same security the same day, compensation on both legs is added together, and charging a full markup on each side of a same-day riskless transaction reads as excessive.
Exam angle
Two calculation moves decide these items: measure riskless-principal markup from prevailing market price, not cost, and combine compensation on both legs of concurrent same-day trades before judging reasonableness against the 5% guideline.
Memory hook:Markup from market, not cost; concurrent trades add both legs; 5% is a guide, not a shield.
Series 9 & 10 concept 31 of 60
Breakpoint Sales (FINRA 2342): Letters of Intent, Rights of Accumulation, and Detecting Diligent-Entry Violations
A breakpoint sale happens when a rep sells a customer a dollar amount just below a mutual fund breakpoint, collecting a higher sales charge than the customer would have paid for a slightly larger purchase. FINRA 2342 requires diligence: reps must know the fund's breakpoint schedule and ask about existing holdings. Two tools legitimately reach breakpoints. A letter of intent gives the customer breakpoint credit immediately for a stated future purchase amount, with 13 months to complete it, and shares are held in escrow until the letter is fulfilled. Rights of accumulation combine prior purchases plus appreciation to qualify the current trade for a lower sales charge. Supervisors flag purchases that land suspiciously just under a breakpoint.
Exam angle
The trap is the just-under-breakpoint purchase. LOI means 13 months to complete with escrowed shares; rights of accumulation count prior purchases plus appreciation. Both are legitimate; the near-miss sale is not.
Memory hook:LOI: credit now, 13 months to pay, shares in escrow; accumulation counts everything already bought.
Series 9 & 10 concept 32 of 60
Variable Annuity Supervision (FINRA 2320): 1035 Exchange Suitability, Senior-Specific Red Flags, and Free-Look Windows
FINRA 2320 imposes heightened supervision on variable annuities. A 1035 exchange, swapping an existing annuity for a new one, is tax-free but rarely cost-free: the customer restarts surrender charges and can lose accumulated guarantees, so the principal must compare contracts, costs, riders, and benefits before approving. Senior-specific red flags include long surrender periods sold to elderly customers, rapid serial exchanges, and any hint of guaranteed-return language. The free-look window, set by state insurance law and commonly around 30 days, lets the customer cancel for a full refund, and the firm must disclose it. Replacement or exchange disclosures are required when the sale involves another insurer's contract.
Exam angle
The hinge is that a 1035 exchange is tax-free but not economically free: restarted surrender charges and lost guarantees drive suitability. Free-look length comes from state insurance law, not FINRA.
Memory hook:1035 swaps the wrapper tax-free; surrender clocks and free-look refunds come from the state.
Series 9 & 10 concept 33 of 60
Direct Participation Program Supervision (FINRA 2310): Concentration Limits and Income-Net-Worth Suitability Tests
FINRA 2310 governs direct participation programs, and the concentration standard is the number to memorize: for natural persons, the firm must have a reasonable basis to believe the purchase does not exceed 20% of the customer's net worth in DPPs, with net worth calculated excluding the customer's home, furnishings, and personal automobiles. The rule also expects attention to whether the program's illiquidity fits the customer's income and cash needs. Supervisors verify the net worth documentation behind each sale, not just the rep's say-so. Because DPPs are illiquid, tax-driven, and long-term, a sale to a customer with modest net worth or short horizons is a suitability failure even if the customer signed everything.
Exam angle
The calculation is the answer: 20% of net worth in DPPs, and the exclusion of home, furnishings, and personal autos changes the denominator. Watch for items testing what counts in net worth.
Memory hook:DPPs cap at 20% of net worth, minus house, furniture, and cars.
Series 9 & 10 concept 34 of 60
IPO Restrictions (FINRA 5130/5131): Restricted Persons, Spinning, and New-Issue Allocation Fairness
FINRA 5130 keeps new equity IPOs away from restricted persons: associated persons of member firms, their owners, and certain related persons and accounts cannot buy hot new issues, though narrow exceptions exist, such as purchases by certain investment companies. FINRA 5131 targets spinning: allocating coveted IPO shares to executives or directors of companies that are, or may become, investment banking clients, in exchange for banking business, is prohibited. Allocations must rest on legitimate criteria, and firms must police the practice. The supervisor's checklist is concrete: screen the allocation book against the firm's restricted-persons list and cross-check allocations against current and prospective banking relationships before the deal prices.
Exam angle
Separate the two rules: 5130 bans restricted persons from buying new issues, while 5131 bans spinning, the quid pro quo of hot shares for banking business. Screening lists versus allocation motives is the distinction.
Memory hook:5130 blocks insiders from IPOs; 5131 blocks spinning shares for banking favors.
Series 9 & 10 concept 35 of 60
Insider Trading Supervision: Rule 10b5-1, MNPI Information Barriers, Section 15(g) Policies, and Controlling-Person Liability
Rule 10b5-1 defines trading on the basis of material nonpublic information and provides the famous defense: a written trading plan adopted before the person became aware of the MNPI, specifying amounts, prices, and dates, can be an affirmative defense. Supervision operates through structure. Information barriers restrict the flow of inside information between banking and trading personnel, supported by restricted and watch lists that flag securities and people. Exchange Act Section 15(g) requires written policies and procedures reasonably designed to prevent misuse of MNPI. Controlling-person liability is the supervisor's personal stake: the Insider Trading and Securities Fraud Enforcement Act imposes civil penalties on supervisors who recklessly fail to prevent or detect insider trading by people they control.
Exam angle
The 10b5-1 plan works only if adopted before awareness of MNPI and predetermines trades. Section 15(g) demands written MNPI policies. Controlling-person penalties attach for reckless supervisory failure, not just for trading yourself.
Memory hook:Plan before you know, write the policies under 15(g), and supervisors pay for reckless blindness.
Series 9 & 10 concept 36 of 60
Manipulation Detection: Exchange Act Section 9(a), Marking the Close, FINRA 5210, and Anti-Intimidation (5240)
Exchange Act Section 9(a)(2) is the core manipulation prohibition: effecting transactions that create an actual or apparent active trading pattern or raise a security's price to induce others to buy. Marking the close, executing trades late in the session to influence the official closing price, is a classic violation that distorts benchmarks and statements. FINRA 5210 bans the tools of fake markets: wash sales, matched orders, fictitious quotations, and transactions with no economic purpose. FINRA 5240, the anti-intimidation rule, prohibits threats or coercion aimed at influencing anyone's market decisions. Supervisors hunt for trades with no economic rationale, unusual concentration near the close, and volume spikes without news.
Exam angle
Match conduct to provision: 9(a)(2) covers inducing trades through apparent activity, marking the close targets the closing print, 5210 bans fictitious trades, and 5240 bans intimidation. No economic purpose is the tell.
Memory hook:9(a)(2) fakes activity, marking the close fakes the print, 5210 fakes the trade, 5240 bullies the trader.
Series 9 & 10 concept 37 of 60
Market Access Rule 15c3-5: Pre-Trade Risk Controls, Credit Thresholds, and Erroneous Order Prevention
SEC Rule 15c3-5 applies to any broker-dealer with market access, whether for its own proprietary trading or access provided to customers. Before providing access, the firm must implement pre-trade risk controls: credit and capital thresholds that reject orders exceeding the customer's or firm's buying power, and erroneous order prevention that catches duplicates, fat-finger quantities, and prices far from the market. The rule also requires regulatory compliance controls and an annual CEO certification that the controls are in place. The supervisory decision is binary: no controls, no access. A firm that lets a customer's orders reach the market without these checks has violated the rule regardless of whether anything went wrong.
Exam angle
The rule is preventive, not remedial: pre-trade credit thresholds and erroneous-order checks must exist before access is granted, and the annual CEO certification is a required element. No controls means no access.
Memory hook:15c3-5: no risk controls, no market access; the CEO certifies it yearly.
Series 9 & 10 concept 38 of 60
Employee Trading Supervision: FINRA 3240 Borrowing Limits, 2150 Sharing and Guarantees, and Restricted Securities Lists
FINRA 3240 prohibits borrowing from or lending to customers unless the customer falls within narrow categories: a financial institution regularly engaged in lending, an affiliate, or an immediate family member, and then only under firm procedures. FINRA 2150 bans guarantees of a customer's account against loss and bans sharing in a customer's account unless the customer provides written authorization and the associated person shares proportionally in profits or losses. Restricted securities lists are the surveillance layer: firms maintain lists of securities employees may not trade because of MNPI concerns, IPO restrictions, or watch-list status. Supervisors compare employee trade activity, in internal and outside accounts under Rule 3210, against those lists.
Exam angle
The exceptions are the answer: borrowing is allowed only from lending institutions, affiliates, or immediate family under procedures. Sharing requires written authorization plus proportional sharing; guarantees are flatly prohibited.
Memory hook:Borrow only from banks, affiliates, or family; share only in writing and proportionally; never guarantee.
Series 9 & 10 concept 39 of 60
Switching Packaged Products and Complex Product Sales: UITs, ETFs, Closed-End Funds, and Structured Product Review
Switching packaged products means moving a customer out of one fund, UIT, ETF, or closed-end fund and into another. Done to generate new sales charges, it is churning in disguise, and each switch must independently satisfy suitability and serve the customer's best interest. The products differ enough to matter: UITs have fixed maturities and front loads, closed-end funds trade at premiums or discounts to NAV, and ETFs carry market-price risk. Structured products demand heightened review because their principal protection is usually contingent and their payoff math is opaque; principals must understand the features and confirm the rep did too before approving the sale. Complexity raises the supervisory bar; it does not lower the suitability bar.
Exam angle
The hinge is motive and fit: a switch that generates a new sales charge without a corresponding customer benefit is churning. Structured product approval requires demonstrated understanding of contingent protection and payoff terms.
Memory hook:Every switch recharges the fee engine; every structured product hides its math.

Series 9 & 10 concept 40 of 60
Retail Communication Definition (FINRA 2210): The 25-Plus/30-Day Test, Pre-Approval, and Filing Obligations
Under FINRA 2210, a retail communication is any communication, electronic or otherwise, distributed to more than 25 retail investors within any 30 calendar-day period. Drop to 25 or fewer retail investors and it is correspondence, with lighter approval obligations. Institutional communications to qualified institutional buyers and similar recipients sit outside the retail definition entirely. Retail communications require pre-approval by a registered principal before first use or distribution, subject to exceptions such as previously approved templates. Filing rules follow: most new retail communications must be filed with FINRA within 10 business days after first use, while certain categories, including mutual fund and options communications, must be filed before use. Content must be fair, balanced, and not misleading.
Exam angle
The 25-plus in 30 days line splits retail communication from correspondence and changes the approval and filing answer. Pre-approval by a principal is required; most filings are within 10 business days after first use, not before.
Memory hook:More than 25 retail investors in 30 days means retail communication: principal approves first, FINRA files after.
Series 9 & 10 concept 41 of 60
Correspondence Supervision: Definition, Review Standards, and Electronic Communication Archiving
Correspondence under FINRA Rule 2210 is any written or electronic communication distributed to 25 or fewer retail investors within any 30 calendar-day period. It does not need principal pre-approval, but the firm must supervise it through written procedures: a principal reviews a defined sample on a periodic basis, and a representative with a disciplinary history tied to communications gets heightened, defined review. Electronic messages get no special treatment—an email, text, or social media post is correspondence just like a letter. The firm must also retain these communications under the books-and-records rules, so archiving text and chat platforms is a supervisory obligation, not an IT convenience.
Exam angle
The hinge is the 25-or-fewer, 30-day test. Cross it and the piece becomes retail communication requiring principal pre-approval. Also watch the trap that electronic communications follow identical rules to paper—candidates often assume texts or social posts are exempt.
Memory hook:Twenty-five retail recipients in 30 days: correspondence. Twenty-six: retail communication needing pre-approval.
Series 9 & 10 concept 42 of 60
Institutional Communications: Qualification Tests, Spot-Check Review, and Why Pre-Approval Is Not Required
FINRA Rule 2210(a)(3) defines an institutional communication as one distributed exclusively to institutional investors—banks, insurance companies, broker-dealers, investment companies, and similar sophisticated entities—with no reasonable basis to believe it will reach a retail investor. The trade-off for this exemption is supervision, not approval: no principal pre-approval is required, but a principal must conduct a spot-check review on a periodic basis defined in the firm's written procedures. The definition is functional. If a representative forwards the piece to retail prospects, or the firm knows retail investors will see it, the communication is reclassified as retail and needs approval.
Exam angle
Two hinges: the recipient must qualify as institutional under the rule's list, and the firm must have no reasonable basis to expect retail exposure. A communication forwarded to even one retail prospect becomes retail communication requiring pre-approval.
Memory hook:Institutional means exclusive institutional audience; one retail forward reclassifies it.
Series 9 & 10 concept 43 of 60
Content Standards and Red Flags: Guarantees, Performance Projections, Balanced Presentation, and Senior Designations
FINRA Rule 2210 content standards apply to every category of communication, not just retail pieces. Material must be fair and balanced, so benefits and risks travel together—promoting a fund's returns without its risks violates the standard regardless of the audience. Guarantees against loss are flatly prohibited, and projections need a reasonable basis with underlying assumptions available. Watch performance claims: past performance must not imply future results, and related performance requires appropriate disclosure. Senior designations get special treatment under 2210(d)(8): a representative may use only designations from accredited programs, must use them accurately, and cannot imply expertise in products they do not sell.
Exam angle
Red flags change the answer: a guarantee, "risk-free" language, or unbalanced performance presentation fails content standards even when approval mechanics were followed. Senior designations must come from accredited programs—self-conferred titles fail.
Memory hook:No guarantees, balance risk with reward, and senior titles must be earned from accredited programs.
Series 9 & 10 concept 44 of 60
Telemarketing Supervision (FINRA 3230 and MSRB G-39): Time-of-Day Windows, Do-Not-Call Lists, and Firm DNC Obligations
FINRA Rule 3230 governs cold calls by members. Calls to prospective customers are limited to 8 a.m. through 9 p.m. local time at the called party's location. The firm must subscribe to the National Do-Not-Call Registry and scrub its calling lists against it at least every 31 days. Separately, the firm must maintain its own internal do-not-call list for people who ask that firm to stop calling, and those requests carry no expiration. An established business relationship preserves some calling rights, but a person who asks onto the firm's list is off-limits permanently. MSRB Rule G-39 mirrors these mechanics for municipal securities activities.
Exam angle
Two lists, two rules: the national registry gets checked every 31 days, but internal firm DNC requests never expire. The 8 a.m.–9 p.m. window uses the called party's local time, not the caller's time zone.
Memory hook:8 to 9 local time; national list scrubbed every 31 days; internal list lasts forever.

Series 9 & 10 concept 45 of 60
Options Account Approval Tiers: The Five Authorization Levels, ROP Approval, and Uncovered Writer Requirements
Firms tier options approval so authority matches customer sophistication and finances. The standard five levels run: covered call writing; purchases of calls and puts; spreads; short straddles and combinations; and uncovered writing of puts or calls. Each account must be approved in writing by a registered options principal before any order is accepted, and the approval level must appear on the new account form. Uncovered writing triggers an extra step: the ROP must verify the customer meets the firm's minimum net equity requirement and has the financial resources to sustain potentially unlimited losses. Trading outside the approved tier is a supervisory violation, not a paperwork slip.
Exam angle
The hinge is matching strategy to tier: a customer approved only for covered calls cannot sell naked puts. Uncovered writing requires the ROP's separate financial determination, including minimum net equity, before approval is granted.
Memory hook:Five tiers climb from covered calls to naked writing; the ROP signs each rung.
Series 9 & 10 concept 46 of 60
Options Disclosure Document Delivery (FINRA 2360(b)(11)) and the Special Statement for Uncovered Writers
Before or with the confirmation of a customer's first options transaction, the firm must deliver the current Options Disclosure Document—Characteristics and Risks of Standardized Options—and obtain the customer's signed acknowledgment, retained in the file. FINRA Rule 2360(b)(11) drives this. When the ODD is materially amended, the firm must furnish the updated disclosure. Customers approved for uncovered writing get a second document: the Special Statement for Uncovered Writers, delivered at or before approval of that authority. It spells out the unlimited-loss mechanics of short calls and the substantial-loss profile of short puts. The supervisor's job is sequencing—no uncovered trade before both documents are in the customer's hands.
Exam angle
Two documents, two triggers: the ODD goes out before or with the first trade confirmation, while the Special Statement for Uncovered Writers must precede or accompany uncovered-writing approval. Sequence violations flip the answer.
Memory hook:ODD with first trade; Special Statement before naked-writing approval.
Series 9 & 10 concept 47 of 60
Options Suitability and Reg BI: Strategy-Level Analysis for Spreads, Straddles, and Institutional Customer Exemptions
Suitability for options is strategy-level, not product-level. Reg BI's care obligation requires the supervisor to ask whether this specific structure—spread, straddle, or naked write—fits this customer's risk tolerance, objectives, and financial capacity. A debit spread with defined loss may suit a moderate investor who could never handle a short straddle's unlimited downside. Institutional customers get a narrower path: the suitability obligation does not apply when the firm has a reasonable basis to believe the institution can evaluate the risks independently and the institution represents it is exercising independent judgment. That exemption is earned through documentation, not assumed from the account type.
Exam angle
The institutional exemption hinges on two documented facts: the firm's reasonable belief the institution can evaluate risk, plus the institution's express statement of independent judgment. Absent either, full suitability and Reg BI apply.
Memory hook:Institutions escape suitability only by proving they can evaluate risk themselves.
Series 9 & 10 concept 48 of 60
Options Margin by Strategy (FINRA 4210 and Cboe 10.3): Short Straddles, Spreads, and Guaranteed Accounts
Margin for options follows the strategy, not a flat percentage. A debit spread is paid in full—the premium is the maximum loss. A credit spread's requirement equals the difference between strikes. A short straddle is the classic exam calculation: the requirement equals the total premium received plus the greater of the short call margin requirement or the short put margin requirement—never both sides added together. Guaranteed accounts under Cboe Rule 10.7 let one customer guarantee another's obligations: the guarantor must receive the ODD and sign a written guarantee, and the ROP must approve the arrangement before it protects anything.
Exam angle
Short straddle margin equals the total premium received plus the greater of the call or put requirement—never both sides added together. For guaranteed accounts, the guarantor must receive the ODD and sign a written agreement, or the guarantee is void.
Memory hook:Short straddle margin: premium plus the greater side, never both; guarantors sign and get the ODD.
Series 9 & 10 concept 49 of 60
Discretionary Options Accounts: Written Authorization, ROP Acceptance, and the Time-and-Price Exception
Discretion in an options account requires three pieces: written authorization from the customer, written acceptance by the registered options principal, and the customer's acknowledgment of the ODD. Cboe Rule 9.4 and FINRA Rule 2360(b)(18) both apply. The ROP's acceptance is a genuine review—the principal must confirm the strategy fits the customer, not just stamp the form. Time-and-price discretion is the exception: a representative may choose when and at what price to execute a customer's order that specifies the security, quantity, and action, with no written authorization and no separate ROP acceptance required, though the firm still supervises the activity. Discretion exercised beyond that scope is an unauthorized trade.
Exam angle
Full discretion needs written customer authorization plus ROP acceptance. Time-and-price discretion on a customer-specified order—security, quantity, action—requires neither written authorization nor ROP acceptance, though the firm still supervises the activity.
Memory hook:Full discretion: customer writes it, ROP accepts it; time-and-price needs neither.

Position Limits (FINRA 2360(b)(3), Cboe 8.30): Aggregation Across Accounts and the Hedged-Position Exemption
Position limits cap the number of options contracts on one side of the market per underlying security, set by the exchange for each class. The supervisor aggregates across accounts: long calls plus short puts count on the bullish side; long puts plus short calls count on the bearish side, combined across all accounts with the same beneficial ownership. Exercise limits equal position limits. The hedged-position exemption under Cboe Rule 8.30 lets a bona fide hedger exceed the limit with exchange approval—the position must genuinely offset risk in an underlying holding, and the firm must document the hedge and obtain approval before building the position.
Exam angle
Aggregation is the hinge: same beneficial owner means positions across multiple accounts combine. Long calls and short puts sit on the same side—candidates often treat them as offsetting when they actually aggregate.
Memory hook:Long calls and short puts are teammates; same beneficial owner means added together.
Series 9 & 10 concept 51 of 60
Exercise Limits and Contrary Exercise Advice: Cboe 8.42 Mechanics and the Five-Session Rule
Exercise limits mirror position limits, and the five-session rule closes the loophole: a customer's total exercises across any five consecutive business days cannot exceed the exercise limit for that class. Without it, a trader could stay under the position limit while churning exercises through the week. Contrary exercise advice works the other direction—OCC automatically exercises expiring options that are in the money by at least one cent, so a holder who does not want that exercise must instruct the firm to deliver contrary advice to OCC before the expiration-day cutoff. The firm's procedures must capture that instruction and route it in time.
Exam angle
The five-session rule aggregates exercises over five consecutive business days—checking only today's position misses the violation. Contrary exercise advice blocks OCC's automatic exercise of expiring in-the-money options.
Memory hook:Five sessions cap exercises; contrary advice opts out of auto-exercise.
Series 9 & 10 concept 52 of 60
Large Options Position Reporting (FINRA 2360(b)(5)): Thresholds, Aggregation, and Reporting Timelines
FINRA Rule 2360(b)(5) requires reporting when a customer's position in a single class of listed options reaches 200 contracts on one side of the market. The supervisor aggregates across all accounts with the same beneficial ownership before testing the threshold, just as with position limits. Once the level is crossed, the firm reports the position to FINRA by the end of the next business day. The report identifies the customer, the class, and the size. The practical supervisory point is that large position reporting is a monitoring tool for concentrated positions—firms need surveillance that flags the threshold before the report is due, not after.
Exam angle
The trigger is 200 contracts in one class on one side of the market, aggregated by beneficial owner, reported to FINRA by end of the next business day. Counting both sides separately is the classic trap.
Memory hook:Two hundred contracts, one class, one side—report to FINRA by next business day.
Series 9 & 10 concept 53 of 60
Order Origin Codes, Trades Serving No Economic Purpose, and the Guarantees and Loss-Assumption Prohibitions (Cboe 9.12, 9.13)
Every options order carries an origin code telling the exchange who is trading and why: O for a customer opening a position, C for a customer closing one, F for firm, M for market maker, P for proprietary, E for error, and similar codes for broker-dealer and tender-related activity. Accurate marking is a supervisory duty because false codes conceal violations. Cboe Rule 9.12 prohibits guaranteeing a customer against loss or sharing in a customer's account; Rule 9.13 bars a member from assuming a customer's losses. Trades serving no economic purpose—wash trades executed to create volume or appearance—are manipulation and fail under these provisions and the just-and-equitable principles.
Exam angle
O opens a customer position; C closes one—reversing them hides activity. Guarantees (9.12) and assuming losses (9.13) are prohibited regardless of intent, and no-economic-purpose trades are never acceptable.
Memory hook:O opens, C closes; never guarantee losses, share accounts, or trade for show.
Series 9 & 10 concept 54 of 60
Exercise and Assignment Mechanics: OCC Allocation, FIFO vs. Random Methods, and Customer Notification
Exercise flows downhill from OCC. When a customer exercises, the firm submits the exercise notice to OCC, which allocates assignments among clearing members—randomly or first-in, first-out. The clearing firm then allocates to its customers using its chosen method, FIFO or random, and must notify customers which method applies. Assignment to a short customer is typically communicated by the next business day. The supervisor's checklist: confirm the exercise notice reached OCC before the cutoff, confirm the allocation method was disclosed, and confirm assigned customers were notified promptly. Missed notifications create complaint risk even when the trade itself was flawless.
Exam angle
OCC allocates to clearing members randomly or FIFO; the firm picks its own method for customers but must disclose it in advance. Notification of assignment is a required step, not a courtesy.
Memory hook:OCC assigns, the firm allocates FIFO or random, and the customer must be told which.
Series 9 & 10 concept 55 of 60
Options Trade Error Correction: Cboe 6.5 Obvious Error Standards, Cancel-and-Rebill Discipline, and Price-Binding Rules
Cboe Rule 6.5 governs obvious errors: an execution whose price deviates materially from the reference or theoretical price. The aggrieved party must invoke the rule promptly—within the short window the rule specifies after execution—and the exchange then nullifies or adjusts the trade. Cboe Rule 5.11 supplies the default: the reported trade price is binding despite an erroneous report unless nullified under 6.5. Internally, errors go to a designated error account, and cancel-and-rebill discipline applies: the firm documents the error, corrects it, and never reverses a trade simply because the customer profited or the market moved.
Exam angle
Price is binding unless the obvious error rule is invoked within its tight post-execution window. Cancel-and-rebill cannot be used to unwind a customer's favorable fill—that is the trap answer.
Memory hook:Obvious errors need a fast, formal claim; otherwise the printed price stands.

Options Retail Communications (FINRA 2220): Pre-Approval, Exchange Filing, Risk Disclosure, and Worksheet Standards
Options retail communications face a second layer on top of FINRA Rule 2210. Rule 2220 requires a registered options principal to approve each retail options communication before first use—pre-approval, not post-review. Most approved pieces must then be filed with the appropriate options exchange within 10 calendar days after first use. Content must present risks: the standard disclosure that the maximum loss on an uncovered option can be substantial or unlimited, and that support documentation is available upon request. Options worksheets—charts computing breakevens and profit and loss—count as communications too, so the ROP must approve them and the firm must retain them as records.
Exam angle
ROP pre-approval comes before first use, then filing with the exchange within 10 calendar days after first use. Worksheets count as retail communications and need the same approval.
Memory hook:ROP approves first, the exchange gets its copy within 10 days, and worksheets are communications too.
Series 9 & 10 concept 57 of 60
Options Correspondence and Institutional Communications: Approval Distinctions and Content Standards Under Cboe 9.15
Options communications split along the same FINRA 2210 lines, with Cboe Rule 9.15 mirroring them. Correspondence—25 or fewer retail investors within 30 days—needs no pre-approval, but the firm's written procedures govern review, and a representative with a communications-related disciplinary history gets defined heightened review. Institutional communications distributed exclusively to institutional investors need no approval; a principal spot-checks them periodically. Content standards never relax: no guarantees, balanced presentation of risks and rewards, and accurate disclosure of the mechanics and potential losses. The trap is audience drift—a piece drafted as institutional becomes retail the moment a representative routes it to retail prospects.
Exam angle
Neither category needs ROP pre-approval, but both must pass content standards and defined supervisory review. Redirect an institutional piece to retail and it becomes retail communication requiring approval.
Memory hook:Correspondence gets sampled, institutional gets spot-checked, and content standards never sleep.

Breakeven and Max Profit/Loss Calculations: Covered Calls, Straddles, and Debit Spreads Under Exam Conditions
Exam math rewards structure over memorization. Covered call: breakeven equals stock purchase price minus premium received; max profit equals premium plus strike minus stock cost; max loss equals stock cost minus premium. Long straddle: breakevens sit at strike plus total premium and strike minus total premium; max loss is the combined premium. Debit call spread: max loss is the net debit paid; max profit is the difference between strikes minus the net debit; breakeven is the lower strike plus the net debit. Write the four numbers—strikes and premiums—before answering, and label the buyer and seller.
Exam angle
For spreads, max profit is strike difference minus net debit and breakeven is lower strike plus net debit—reversing the two is the standard wrong answer. Straddle breakevens use total premium on both sides.
Memory hook:Debit spread: lower strike plus debit to break even; strike spread minus debit to profit.
Series 9 & 10 concept 59 of 60
Tax Treatment of Options Transactions: Exercise and Assignment Consequences, Section 1256 Index Options, and Qualified Covered Calls
Tax follows the transaction. When a call buyer exercises, the premium becomes part of the stock's basis; when the call writer is assigned, the premium joins the sale proceeds. Exercising a put fixes the sale price at the strike, with the premium adjusting the result. Broad-based index options are Section 1256 contracts: marked to market at year end, with gains split 60 percent long-term and 40 percent short-term regardless of actual holding period. Qualified covered calls preserve the holding period on the underlying stock, but deep-in-the-money calls do not qualify—selling them can suspend the clock. Cash-settled index options sidestep delivery entirely.
Exam angle
Section 1256 applies to broad-based index options: 60/40 treatment with no holding-period requirement. Deep-in-the-money covered calls are disqualified, which tolls the stock's holding period.
Memory hook:Index options: 60/40 marked to market; deep-in-the-money covered calls break the clock.

Contract Adjustments and Trading Mechanics: Why Cash Dividends Do Not Adjust Contracts, the 25% Threshold, and Market Participant Roles
Contract adjustments turn on the corporate action. Cash dividends never adjust listed options—the market simply prices them in. Stock splits and stock dividends do adjust. The 25 percent threshold sets the method: adjustments of 25 percent or more, like a 2-for-1 split, change the number of contracts and the strike price; smaller stock dividends change the number of shares deliverable per contract, producing non-standard contracts. Supervisors verify adjusted terms before approving trades. On roles: market makers trade for their own accounts, designated primary market makers carry quoting obligations, and floor brokers execute agency orders for the public.
Exam angle
Cash dividends never trigger adjustment—that is the recurring trap. At 25 percent or more, contracts and strikes are adjusted; below it, shares per contract change instead.
Memory hook:Cash never adjusts; 25 percent or more changes contracts, less changes shares delivered.
Turn the Concepts Into Exam Points
A concept is not secure until you can recognize it when the wording changes. Run a short mixed quiz, review every miss, and return to the numbered concept that explains the underlying rule. That loop turns passive recognition into the fast judgment the Series 9 & 10 demands.
