FREE SIE Study Guide 2026: A Complete, FINRA-Aligned Walkthrough

This free SIE study guide is the core of your SIE study materials — it walks through every topic on FINRA’s Securities Industry Essentials exam, organized into the same four functions FINRA uses to build the test.^[2]

And it’s interactive, not a wall of text: every module has built-in checkpoint quizzes, flashcards, and practice questions, so you learn by doing — not just reading.

Read it module by module, test yourself at each checkpoint, then round out your free SIE study resources with our practice exam, flashcards. The best part of the SIE: you can sit it without a sponsor, so this is the perfect place to start a securities career.

SIE Exam Snapshot

The exam is weighted heavily toward one function — products and their risks is nearly half the test — so spend your time accordingly:^[2]

Module 1 · Knowledge of Capital Markets

Function 1 — 16% of the exam (about 12 questions). Before you can understand products, you need the stage they trade on: who regulates the markets, who participates, how the primary and secondary markets differ, and how the economy moves prices. This module is the foundation for everything that follows.

1.1 Regulators, SROs & Market Participants

U.S. securities regulation is layered. Federal law sits on top — chiefly the Securities Act of 1933 (the primary market) and the Securities Exchange Act of 1934 (the secondary market and the people in it).^[3] The 1934 Act created the SEC, the federal agency that oversees the entire industry and to which the self-regulatory organizations answer.^[4] Below the SEC sit the SROs:

The participants in the markets include issuers (who sell securities to raise capital), broker-dealers (a broker acts as an agent for a commission; a dealer acts as a principal for its own account and earns a markup), investors (retail and institutional), investment advisers (paid for advice), municipal advisors, transfer agents (track ownership and handle certificates), and clearing/custody firms that settle and hold securities.

1.2 Market Structure & Types of Markets

The single most-tested distinction here is primary vs. secondary market. In the primary market the issuer sells new securities and receives the proceeds; in the secondary market investors trade existing securities with each other and the issuer gets nothing.

Prices in the secondary market are quoted as a bid and ask: investors sell at the bid and buy at the ask, and the gap between them is the spread. An auction market (the exchange) matches the highest bid with the lowest offer; a negotiated market (OTC) sets prices through dealer negotiation.

1.3 Economic Factors

The SIE expects you to know how the broad economy affects securities. The economy moves through a repeating business cycle — expansion, peak, contraction, and trough:

Two recession (contraction) signposts are tested: a recession is commonly defined as two or more consecutive quarters of declining GDP, and a depression is a prolonged, severe contraction (often cited as six or more quarters). The government has two levers to influence the cycle:

The Fed’s main day-to-day tool is open-market operations run by the FOMC: buying Treasuries injects money and lowers rates (easy money); selling them drains money and raises rates (tight money).^[5] Watch the yield curve too — normally upward-sloping (longer maturities pay more); an inverted curve (short rates above long rates) is a classic recession warning. Key indicators include GDP, CPI (inflation), and the unemployment rate.

1.4 The Primary Market & Offerings

The Securities Act of 1933 requires non-exempt issuers to register with the SEC and deliver a prospectus so investors can make an informed decision.^[3] Registration does not mean the SEC approves or guarantees the security — it only confirms that required disclosures were made.

Not everything must register. Exempt securities include U.S. government and municipal securities, and bank issues.

Exempt transactions include the private placement under Regulation D, sold mainly to accredited investors (plus up to 35 non-accredited), and Regulation A offerings.^[6]

A first-time sale to the public is an initial public offering (IPO); a public company selling more shares makes an additional (follow-on) offering.

Module 2 · Understanding Products and Their Risks

Function 2 — 44% of the exam (about 33 questions). This is the heart of the SIE. You need to recognize every major product, what gives each its value, and the risks that come with it. Budget the most study time here by far.

2.1 Equity Securities

Common stock represents ownership. Holders get voting rights, the potential for growth and variable dividends, but stand last in line if the company is liquidated.^[7] Preferred stock trades growth and votes for a fixed dividend and priority over common in dividends and liquidation.

Preferred comes in flavors worth knowing: cumulative (missed dividends accrue and must be paid before common), participating (can receive extra beyond the stated rate), convertible (exchangeable for common), and callable (the issuer can redeem it). Other equity-related products include rights (short-term, let existing holders buy new shares at a discount to avoid dilution), warrants (long-term, often a sweetener attached to a bond), and ADRs (American Depositary Receipts — a way to own foreign shares that carry currency risk).

Dividends follow a four-date timeline. Know the order and which one matters most:

2.2 Debt Securities

A bond is a loan to the issuer. The investor is a creditor, not an owner, and is paid interest (the coupon) plus return of par ($1,000) at maturity.^[8] The most-tested idea is the inverse relationship: when interest rates rise, existing bond prices fall, and vice versa. That sensitivity is greatest for long-maturity, low-coupon bonds.

Bonds carry credit (default) risk, graded by rating agencies — BBB-/Baa3 and above is investment grade; below that is high-yield (junk). Corporate bonds can be secured (backed by collateral — mortgage bonds, equipment trust certificates) or unsecured (debentures, backed only by the issuer’s credit). Money-market instruments (T-bills, commercial paper, CDs, banker’s acceptances) are short-term (≤1 year) debt used for liquidity.

2.3 U.S. Government & Municipal Securities

Treasury securities are direct obligations of the U.S. government and considered free of credit risk.^[9] Their interest is exempt from state and local tax but federally taxable. Know the ladder:

Municipal bonds are issued by states and localities; their interest is generally exempt from federal income tax (and from state tax for in-state residents — the “double exemption”).^[10] The two main types are general obligation (GO) bonds, backed by the issuer’s taxing power (often needing voter approval), and revenue bonds, backed only by the income of a specific project (a toll road, airport, or stadium).

2.4 Investment Companies & Packaged Products

Packaged products bundle many securities so a small investor gets instant diversification and professional management. The Investment Company Act of 1940 defines three types of investment company:^[11]

An open-end fund continuously issues redeemable shares priced at NAV, calculated at least daily; orders receive the next computed NAV (forward pricing). Mutual fund share classes differ by how you pay the sales charge: Class A (front-end load, with breakpoint discounts for larger investments), Class B (back-end / contingent deferred sales charge that declines over time), and Class C (level load — higher ongoing 12b-1 fees). ETFs trade intraday on an exchange like a stock and usually track an index at low cost.

Variable annuities and variable life insurance are insurance products that are also securities, because the value rides on a separate account of subaccounts and the investor bears the market risk — so they require a prospectus and a properly licensed rep.^[12] Contrast that with a fixed annuity (guaranteed rate, insurance product only, not a security).

2.5 Options, DPPs & Alternatives

An option is a contract on 100 shares.^[13] A call gives the buyer the right to buy at the strike price (bullish); a put gives the right to sell at the strike (bearish). The buyer pays a premium and has limited risk; the seller (writer) receives the premium and takes on the obligation.

On the SIE you mainly need the vocabulary and the directional logic, not complex multi-leg math.

Other products you should recognize: direct participation programs (DPPs)— limited partnerships (real estate, oil & gas) that pass income, gains, and losses straight through to investors and are illiquid; REITs, which trade like stock and must pass through at least 90% of income to avoid corporate tax; and hedge funds, lightly regulated private funds for accredited/qualified investors that may use leverage and short selling.

2.6 Investment Risk & Return

Every recommendation balances risk and return. The master distinction: systematic risk is market-wide and cannot be diversified away, while unsystematic risk is specific to one company or sector and can be reduced by diversification.

Return comes from income (dividends, interest) and capital appreciation. Total return combines both; current yield = annual income ÷ current price. Remember the trade-off the exam keeps testing: higher potential return always means higher risk, and products like Treasuries sit at the low-risk/low-return end while small-cap equity and DPPs sit at the high end.

Module 3 · Understanding Trading, Customer Accounts & Prohibited Activities

Function 3 — 31% of the exam (about 23 questions). Now the mechanics: how accounts are opened, how orders work, how trades settle, and — heavily tested — what you’re never allowed to do.

3.1 Opening & Maintaining Accounts

Before any account opens, the firm’s Customer Identification Program (CIP) must verify the customer’s name, date of birth, address, and a taxpayer ID (SSN), and check government watch lists.^[17] The account’s registration controls ownership and what happens at death:

Account types also differ by purpose: a cash account requires payment in full; a margin account lets a customer borrow part of the cost under Regulation T (the Fed’s current initial requirement is 50%), and requires a signed margin agreement. Discretionary accounts (where the rep chooses the security, action, or amount) need prior written authorization and close supervision.

3.2 Orders & Trade Execution

Order types are among the most reliable SIE points. Master the four core orders and when each triggers:

Orders are also tagged by duration: a day order expires at the close, while a good-til-canceled (GTC) order stays in force until executed or canceled. Investors go long (buy expecting a rise) or short (borrow and sell expecting a decline — with theoretically unlimited risk). A market maker’s published quote is a firm quote it must honor for the standard size.

3.3 Settlement, Customer Protection & Records

Since May 2024, regular-way settlement for stocks and most bonds is T+1 — one business day after the trade date.^[16] (Options and government securities also settle T+1; cash settlement is same day.) Every recommendation must meet the suitability standard, and for retail customers Regulation Best Interest (Reg BI) requires the firm to act in the customer’s best interest and deliver a relationship summary (Form CRS).^[14][15] Firms must also keep books and records, send trade confirmations by settlement and account statements at least quarterly.

3.4 Prohibited Activities

This is the most heavily tested part of Module 3 — know the bright lines:

Firms must also fight financial crime. The Bank Secrecy Act and AML rules require a written AML program, a designated compliance officer, a Currency Transaction Report for cash over $10,000 in a day, and Suspicious Activity Reports (SARs) for suspicious transactions.^[17] Recognize the three stages of money laundering:

Module 4 · Overview of the Regulatory Framework

Function 4 — 9% of the exam (about 7 questions). The smallest section, but easy points if you know how the industry is organized and how people get — and keep — their registrations.

4.1 SROs & Registration

The regulatory pyramid: Congress writes the laws, the SEC enforces them at the federal level, and the SROs — FINRA, the MSRB, and the exchanges — write and enforce industry rules under SEC oversight.^[4] To work for a member firm, an associated person must be registered: the firm files a Form U4, the person is fingerprinted, and they pass the required qualification exams (the SIE plus a top-off).^[20]

Some people are statutorily disqualified from registration — for example, those with certain felony convictions or securities-related misdemeanors in the past ten years, or those subject to certain regulatory bars. Registered people must also complete Continuing Education: the Regulatory Element annually, plus the firm-delivered Firm Element.^[21]

4.2 Employee Conduct & Reportable Events

Registered representatives owe their firm and customers a duty of disclosure. Several activities require notice or permission:

The Form U4 must be kept current — registered persons report reportable events (certain criminal charges, customer complaints, liens, bankruptcies) generally within 30 days.^[22][23] When a rep leaves, the firm files a Form U5 within 30 days, and the rep’s registration can be reactivated without re-testing if they return within two years (the CE reinstatement window is longer).

How to Use This Study Guide

A study guide is a map, not the whole territory — use it alongside your prep provider’s materials and our practice tools, not on its own:

SIE Glossary

Quick definitions for the terms you’ll see most on the SIE exam:

Accredited investor

An investor meeting income ($200K / $300K joint), net-worth ($1M excluding home), insider, or professional-credential tests — eligible for private (Reg D) offerings.

Backing away

A prohibited practice in which a market maker fails to honor its firm (published) quote for the standard size. Firm quotes must be honored.

Bid and ask

The bid is the highest price a buyer will pay; the ask (offer) is the lowest price a seller will accept. The difference is the spread.

Closed-end fund

An investment company that issues a fixed number of shares in an IPO, then trades on an exchange at a market price that can be above or below NAV.

Common stock

An equity security representing ownership. Holders get voting rights and variable dividends but stand last in line at liquidation.

Currency Transaction Report (CTR)

A report a firm must file for cash transactions exceeding $10,000 in a day, under the Bank Secrecy Act's anti-money-laundering rules.

Diversification

Spreading investments across many securities/sectors to reduce unsystematic risk — the core idea behind packaged products like mutual funds.

ETF

Exchange-traded fund — a basket of securities (often index-tracking) that trades intraday on an exchange like a stock, usually with low expenses.

Form U4

The Uniform Application for Securities Industry Registration — filed by a firm to register an associated person, disclosing employment, disclosures, and exam history.

Insider trading

Trading on, or tipping, material nonpublic information in breach of a duty. Prohibited under the Insider Trading and Securities Fraud Enforcement Act; penalties up to $3\times$ the profit.

Limit order

An order to buy at or below — or sell at or above — a specified price. It guarantees price (or better) but not execution.

Market order

An order to buy or sell immediately at the best available price. It guarantees execution but not price.

Money laundering

Disguising the origin of illegal funds through three stages — placement, layering, and integration. The Bank Secrecy Act and AML rules require firms to detect and report it.

Municipal bond

Debt issued by a state or local government. Interest is generally exempt from federal income tax (and often state tax for in-state residents).

Net asset value (NAV)

A fund's per-share value $= \frac{\text{assets} - \text{liabilities}}{\text{shares outstanding}}$, calculated at least once daily. Mutual fund orders price at the NEXT NAV (forward pricing).

Nominal yield (coupon)

The fixed annual interest a bond pays, set at issuance as a percentage of par ($1,000). It never changes for the life of the bond.

Open-end fund (mutual fund)

A continuously-offered investment company that issues redeemable shares priced at NAV. Shares are bought from and sold back to the fund itself.

Preferred stock

An equity security with a fixed (stated) dividend and priority over common in dividends and liquidation, but usually no voting rights.

Primary market

Where an issuer sells NEW securities to investors to raise capital (an IPO or additional offering). The proceeds go to the issuer.

Private placement (Reg D)

An exempt offering sold mainly to accredited investors (plus up to 35 non-accredited), using a private placement memorandum and a Form D filing — not registered with the SEC.

Prospectus

The full disclosure document an issuer must give buyers of a new, non-exempt security, no later than at confirmation of the sale.

Regular-way settlement

Standard settlement = T+1 (one business day after the trade date) for stocks and most bonds since May 2024. Cash settlement is same day.

Secondary market

Where investors trade ALREADY-ISSUED securities with one another (e.g., on an exchange or OTC). The issuer receives no proceeds.

Securities Act of 1933

The 'Paper Act' — governs the PRIMARY market (new issues). Requires non-exempt issuers to register with the SEC and deliver a prospectus, ensuring full and fair disclosure.

Securities Exchange Act of 1934

The 'People Act' — governs the SECONDARY market and the people in it. Created the SEC, and requires registration of exchanges, broker-dealers, and associated persons.

SIPC

Securities Investor Protection Corporation — insures customer assets (up to $500,000, including a $250,000 cash limit) if a broker-dealer fails. It is NOT protection against market loss.

SRO

Self-Regulatory Organization — an industry body (FINRA, the MSRB, the exchanges) that writes and enforces rules under SEC oversight.

Stop order

A dormant order that becomes a market order once the stock trades at or through the stop price. Used to protect a position or limit a loss.

Suitability / Reg BI

The duty to have a reasonable basis that a recommendation is in the customer's best interest, based on their profile. Regulation Best Interest raised the standard for retail recommendations.

Systematic risk

Market-wide risk that diversification can't remove — market, interest-rate, inflation (purchasing-power), and reinvestment risk.

Treasury securities

Direct debt of the U.S. government: T-bills ($\le$1 yr, sold at a discount), T-notes (2–10 yr), and T-bonds (10–30 yr). Considered free of credit risk; interest is state-tax exempt.

Unit investment trust (UIT)

An investment company with a fixed, unmanaged portfolio and a set termination date. It issues redeemable units and has no board or investment adviser.

Unsystematic risk

Risk specific to one company or industry (business, credit, regulatory, liquidity risk). It CAN be reduced through diversification.

Variable annuity

An insurance/annuity product whose value depends on a separate account of subaccounts. Because the investor bears market risk, it is a SECURITY and needs a prospectus.

Yield to maturity (YTM)

The total annual return if a bond is held to maturity, accounting for coupon income plus any discount or premium to par.
