SIE Study Guide: What Each FINRA Section Actually Covers

How the SIE is structured

The exam pulls from four sections of the FINRA content outline. Every scored question maps to one of them, and the percentages below are how FINRA weights them. There are also 10 unscored pretest questions sprinkled in (you will not know which), so you actually answer 85 questions in the 105 minutes.

A candidate who masters Section 2 and Section 3 has already covered ~75% of the exam. Get those right and you can afford to be merely competent on Sections 1 and 4.

Section 1: Knowledge of Capital Markets (~16%)

This section tests how the U.S. capital markets are structured: who the participants are, what role each plays, and how primary and secondary markets work.

What’s covered:

• Regulators and self-regulatory organizations: SEC, FINRA, MSRB, FRB, FDIC, SIPC
• Market participants: broker-dealers, investment advisers, issuers, institutional investors, retail investors
• Types of markets: primary (issuance) vs secondary (trading), exchanges vs OTC, third and fourth markets
• Economic factors: monetary policy (FOMC, fed funds rate, discount rate), fiscal policy, business cycles, GDP, CPI, yield curve
• Offerings: IPOs, secondary offerings, private placements, the role of underwriters

Common traps:

• Confusing the SEC (federal regulator) with FINRA (SRO for broker-dealers)
• Mixing up monetary policy tools (FRB) with fiscal policy tools (Congress/Treasury)
• The yield curve: normal (upward), inverted, flat, and what each implies

High-yield terms: SEC, FINRA, MSRB, SIPC, FOMC, Regulation T, primary market, secondary market, underwriter, syndicate.

Section 2: Understanding Products and Their Risks (~44%)

The biggest section by a wide margin. This is where most candidates win or lose the exam. It tests every major product category and the risks attached.

What’s covered:

• Equity securities: common stock, preferred stock, ADRs, rights and warrants, restricted and control stock
• Debt securities: corporate bonds, municipal bonds (GO vs revenue), Treasuries (bills, notes, bonds, TIPS), agency securities, money market instruments
• Packaged products: mutual funds (open-end), closed-end funds, ETFs, UITs, REITs, hedge funds, BDCs
• Options: calls and puts, basic strategies, exercise and assignment, intrinsic vs time value
• Variable products: variable annuities, variable life insurance, sub-accounts
• Direct participation programs (DPPs): limited partnerships, real estate, oil and gas
• Derivatives: options basics, brief exposure to futures and forwards
• Risks: market, credit, liquidity, interest rate, inflation, reinvestment, regulatory, political, currency, prepayment, call

Common traps:

• Bond pricing and yield relationships (yield up, price down, and what “premium” vs “discount” means for current yield, YTM, YTC)
• Mutual fund share classes (A, B, C) and breakpoints
• Variable vs fixed annuities (which has investment risk, which has insurance company risk)
• GO bonds (backed by full faith and credit/taxes) vs revenue bonds (backed by project revenue)

High-yield terms: common stock, preferred stock, yield to maturity, duration, GO bond, revenue bond, mutual fund, ETF, REIT, variable annuity, call option, put option, breakpoint, NAV.

Section 3: Understanding Trading, Customer Accounts, and Prohibited Activities (~31%)

The second-largest section. This is the operational and ethical side of the job: how trades happen, how accounts are opened and maintained, and what conduct will get you fined or barred.

What’s covered:

• Order types: market, limit, stop, stop-limit, day, GTC, AON, FOK, IOC
• Trade lifecycle: order entry, execution, clearing, settlement (T+1 since May 2024)
• Account types: cash, margin, joint, custodial (UGMA/UTMA), trust, retirement (IRA, Roth IRA, 401(k), 403(b), 529)
• Customer onboarding: Form CRS, suitability, Reg BI, KYC, AML/BSA, Customer Identification Program, Form U4 basics
• Margin: Reg T initial margin (50%), FINRA maintenance (25% long, 30% short), margin calls
• Corporate actions: stock splits, reverse splits, dividends (cash, stock), mergers, tender offers, ex-dividend date logic
• Prohibited activities: insider trading, front running, churning, painting the tape, freeriding, selling away, market manipulation
• AML red flags: structuring, unusual cash activity, SAR triggers

Common traps:

• Settlement (T+1 for most equities; same-day for options and most government securities)
• Ex-dividend date timing (one business day before record date under T+1)
• Reg T vs FINRA maintenance margin (different rules, different percentages)
• Reg BI vs the old suitability standard (what changed in 2020)

High-yield terms: T+1 settlement, Reg T, Reg BI, KYC, AML, margin call, suitability, fiduciary, churning, insider trading, ex-dividend date.

Section 4: Overview of the Regulatory Framework (~9%)

The smallest section. Tests the regulators, the major laws, and the registration requirements for individuals and firms.

What’s covered:

• Federal securities laws: Securities Act of 1933, Securities Exchange Act of 1934, Investment Company Act of 1940, Investment Advisers Act of 1940, Securities Investor Protection Act of 1970
• Regulators: SEC, FINRA, state securities administrators, SIPC, MSRB, FRB
• Registration: Form U4, Form U5, fingerprinting, statutory disqualification
• CE requirements: Regulatory Element, Firm Element
• Outside business activities, private securities transactions, gifts and gratuities limits ($100/year)
• Communications with the public: retail vs institutional, principal approval requirements, social media

Common traps:

• Confusing the 1933 Act (issuance/registration) with the 1934 Act (secondary trading/exchanges)
• Form U4 (joining a firm) vs Form U5 (leaving)
• Two-year jurisdiction window after termination

High-yield terms: Securities Act of 1933, Securities Exchange Act of 1934, Form U4, Form U5, Regulation Best Interest, statutory disqualification, MSRB.

How to use this guide

Three ways to apply the section weights to your study plan:

1. Weight your hours. If you’re planning ~60 hours of study, allocate roughly 26 hours to Section 2, 19 to Section 3, 10 to Section 1, and 5 to Section 4. The exam respects these weights, so your study should too.

2. Diagnose with practice questions, not chapters. Take a section-tagged practice quiz and look at your accuracy by section. A 60% on Section 2 hurts five times more than a 60% on Section 4. Fix the heaviest weakness first.

3. Use the readiness score, not the question count. “I’ve done 1,000 questions” tells you nothing. “I’m at 78% in Section 2 and 85% everywhere else” tells you exactly what to study tomorrow. See our guide on how long to study for the SIE for pacing.

For the underlying study method (active recall, spaced repetition, four-phase plan), see how to study for the SIE. This guide is the what; that one is the how.

What this guide is not

It is not a content dump. The SIE outline runs over 60 pages with hundreds of subtopics; condensing it to a single article would be either lossy or unreadable. Use this as a navigation map: figure out which section is your weakest, then go deep with practice questions and flashcards in that section.

It is also not a replacement for FINRA’s official outline. If you want the authoritative source, the outline lives on FINRA’s site under “qualification exams.” Treat this guide as a study companion, not a substitute.

The bottom line

The SIE is four sections, weighted unevenly. Section 2 is 44% of the test, so it gets 44% of your time. Section 4 is 9%, so it gets 9% of your time. Candidates who study evenly across sections almost always over-prepare on Section 4 and under-prepare on Section 2, which is the exact wrong tradeoff. Weight your effort to match the exam, drill products and trading until they’re automatic, and the 70% pass line takes care of itself.
