Study guide
This final chapter covers the market-facing side of supervision: execution quality, trading rules and prohibited practices, the municipal securities regime under MSRB rules, and the supervisory architecture of FINRA Rules 3110, 3120, and 3130 that holds the whole program together. These topics reach across the Series 10 outline and supply many of its scenario questions.
Best Execution, Markups, and Trade Reporting
FINRA Rule 5310 requires reasonable diligence to ascertain the best market for a security so the resulting price to the customer is as favorable as possible under prevailing conditions. Diligence factors include the character of the market, the size and type of transaction, the number of markets checked, and the accessibility of quotations. Best execution applies whether the firm acts as agent or principal, and firms that route order flow must conduct regular and rigorous reviews of execution quality, especially where payment for order flow creates conflicts. Pricing fairness in principal trades is governed by the markup policy, the long-standing five percent guideline: five percent is a guide, not a safe harbor, and factors such as security type, availability, price, order size, and disclosure can make a smaller markup unfair or a larger one acceptable. Markups on riskless principal trades, where the firm buys only to fill a known customer order, are measured against the firm's contemporaneous cost. A supervisor reviewing the trading blotter at fictional Crestline Brokerage who sees routine four percent markups on liquid investment-grade bonds should recognize that pattern as indefensible despite sitting under five percent. Trade reporting is the transparency layer: over-the-counter equity trades are reported to a FINRA facility within seconds of execution, corporate and agency bond trades are reported to TRACE, and municipal trades to the MSRB's RTRS system. Regulators have been shortening fixed-income reporting windows toward as little as one minute for many trades, so verify the current deadlines before exam day. Order and execution data also flows into the Consolidated Audit Trail, and supervisors are responsible for the accuracy and timeliness of what their desks report.
Manipulation, Insider Trading, and New-Issue Restrictions
Prohibited practices supply vivid exam scenarios, and the supervisor's job is recognizing them in exception reports. Manipulation includes wash trades, transactions with no change in beneficial ownership designed to paint volume; matched orders arranged between parties; marking the close or open, trading to influence a benchmark price; and front running, trading ahead of a known imminent block order, addressed by FINRA Rule 5270. Spreading false rumors, guaranteeing customers against loss, and sharing in customer account profits without written authorization and proportionate contribution are likewise prohibited. Insider trading, trading while aware of material nonpublic information in breach of a duty, or tipping others who trade, carries severe consequences: civil penalties up to three times the profit gained or loss avoided, criminal fines and imprisonment, and firm liability for failing to maintain barriers. Firms use information barriers, watch lists, and restricted lists to control the flow between investment banking and sales, and a supervisor who hears a representative teasing a pending merger to clients must halt the activity and escalate immediately. FINRA Rule 5130 protects the integrity of initial public offerings of equity securities: restricted persons, including member firms, their associated persons, certain immediate family members, and portfolio managers buying for their own accounts, may not purchase new-issue equity at the offering price. Firms must obtain a representation of eligibility from account holders within 12 months before selling them new issues, and accounts with limited restricted-person ownership may participate under a de minimis allowance of up to ten percent. Companion Rule 5131 prohibits spinning, allocating hot IPO shares to executives of companies to win their investment banking business, and restricts flipping penalties and quid pro quo allocations.
Reg SHO, Order Handling, and Trading Halts
Regulation SHO governs short selling. Every sell order must be marked long, short, or short exempt, and a firm may mark an order long only if the customer owns the security and it is reasonably expected to be delivered by settlement. Before accepting or effecting a short sale, the firm must satisfy the locate requirement: reasonable grounds to believe the security can be borrowed for delivery, documented before execution, with a narrow exception for bona fide market making. Threshold securities, those with persistent large settlement failures, face mandatory close-out requirements, and Rule 201, the alternative uptick rule, activates when a stock falls ten percent from its prior close, permitting short sales for the rest of that day and the next only at prices above the national best bid. Order handling rules protect customers: FINRA Rule 5320 generally forbids a firm from trading for its own account ahead of an unexecuted customer order at the same or better price, subject to exceptions such as institutional customer opt-outs and no-knowledge desks, and limit order display requirements push customer limit orders into public quotations. Marketwide circuit breakers pause all equity trading on severe S&P 500 declines: a seven percent or thirteen percent drop before 3:25 p.m. Eastern triggers a 15-minute halt, and a twenty percent drop stops trading for the day. Single-stock volatility is handled by limit up-limit down price bands. Supervisors also see regulatory halts, such as news-pending halts, during which soliciting orders in the halted security is prohibited. Picture a trading supervisor, Nadia, whose desk holds a customer limit order to buy at 25.10 while a trader buys for the firm at 25.05; unless an exception applies, the customer must be filled.
Municipal Securities: MSRB Rules and 529 Plans
Municipal securities are regulated by the Municipal Securities Rulemaking Board, whose rules FINRA enforces for broker-dealers. Rule G-19 is the municipal suitability rule, requiring a reasonable basis to believe a recommended municipal transaction is suitable based on the customer's investment profile, and for retail customers it now operates alongside Regulation Best Interest. Rule G-30 requires that principal transaction prices, and commissions on agency trades, be fair and reasonable considering all relevant factors, including the security's characteristics and the value of services rendered; related rules require disclosure of markups on many same-day retail principal trades, calculated from the prevailing market price. Rule G-37 attacks pay-to-play: a dealer that makes, or whose municipal finance professionals make, political contributions to officials who can influence the award of municipal securities business is banned from negotiated business with that issuer for two years. The critical exception is de minimis: an MFP may contribute up to 250 dollars per election to a candidate for whom the MFP is entitled to vote without triggering the ban, and dealers file quarterly disclosures of contributions and municipal business. Rule G-17 requires fair dealing with all persons, and time-of-trade disclosure obligations require dealers to disclose material information about a municipal security available through established industry sources. 529 college savings plans are municipal fund securities, sold with a program disclosure document rather than a prospectus; in most states, investors may receive state tax benefits for investing in their home state's plan, so recommending an out-of-state plan requires weighing those forgone benefits, a documented suitability consideration. Supervision of municipal activities must comply with MSRB Rule G-27, which parallels FINRA's supervision rules, and municipal records follow MSRB retention schedules, with many core records kept six years.
Supervisory Systems: Rules 3110, 3120, and Annual Certification
FINRA Rule 3110 requires a supervisory system reasonably designed to achieve compliance, built on written supervisory procedures that state who supervises what, how, and how often. Every registered person is assigned to an appropriately registered supervisor, each type of business has a designated principal, and each Office of Supervisory Jurisdiction, an office executing orders, holding customer funds or securities, structuring offerings, giving final approval of new accounts or retail communications, or supervising other offices, must have at least one on-site principal. Each representative attends at least one annual compliance meeting. Inspection cycles are heavily tested: OSJs and branches that supervise other locations are inspected at least annually, other branch offices at least every three years, and non-branch locations on a regular periodic schedule stated in the WSPs. FINRA has more recently permitted qualifying home offices to be designated residential supervisory locations inspected on the non-branch cycle and has run a voluntary remote inspections pilot; because these programs continue to evolve, confirm their current status when you study. Rule 3110 also mandates risk-based review of correspondence and internal communications, transaction review, and procedures for investigating red flags, including heightened scrutiny of trading by supervisors themselves, with a mechanism ensuring no one is supervised solely by a subordinate. Rule 3120 requires a system of supervisory control policies that independently test and verify the WSPs each year and produce a report to senior management, with expanded content for firms reporting more than 200 million dollars in gross revenue. Rule 3130 caps the structure: the chief executive officer certifies annually that the firm has processes to establish, maintain, review, test, and modify its compliance policies, informed by a meeting with the chief compliance officer within the preceding twelve months. Think of the three rules as build it, test it, certify it.

Exam tips
- Treat five percent as a ceiling on reasonableness, not a floor of safety; liquid, low-risk securities demand smaller markups, and riskless principal markups are measured from contemporaneous cost.
- For G-37, two numbers control: 250 dollars per election, only to candidates the contributor can vote for, and a two-year ban on negotiated business if the exception is blown.
- Know the inspection cycle triad: OSJs and supervising branches annually, other branches every three years, non-branch locations on a stated periodic schedule.
- Map the supervisory rules as a sequence: 3110 builds the system, 3120 tests and reports on it annually, 3130 has the CEO certify it.
- Short sale questions hinge on sequence: mark the order, satisfy the locate before execution, and remember Rule 201 restricts short pricing after a ten percent single-day decline.
