The Securities and Exchange Commission (SEC) was created by which piece of federal legislation?
- The Securities Exchange Act of 1934
- The Investment Company Act of 1940
- The Securities Act of 1933
- The Securities Investor Protection Act of 1970
Show answer and explanation
Answer: The Securities Exchange Act of 1934
The SEC — a federal government agency, not a self-regulatory organization — was established by the Securities Exchange Act of 1934, the same law that regulates secondary-market trading, exchanges, and broker-dealers. A useful frame: 1933 is the "paper act" (registration and prospectus rules for new issues), while 1934 is the "people and places act" (it created the SEC to police the markets where that paper trades). The Investment Company Act of 1940 covers mutual funds and other investment companies, and the Securities Investor Protection Act of 1970 created SIPC, not the SEC.
The Trap: Believing the SEC was created by the Securities Act of 1933 (1933 vs. 1934 Act confusion)
- The Investment Company Act of 1940: Act-mapping confusion: the Investment Company Act of 1940 regulates mutual funds and other investment companies; the SEC already existed and administers it.
- The Securities Act of 1933: Classic 1933-vs-1934 confusion: students associate the SEC with the first major federal securities law. The 1933 Act governs new-issue registration and prospectuses but did not create the SEC.
- The Securities Investor Protection Act of 1970: SEC-vs-SIPC confusion: SIPA created SIPC, the nonprofit that protects customer assets when a broker-dealer fails — it did not create the SEC.

An issuer's registration statement for a new stock offering has just been declared effective by the SEC. Which statement accurately describes what this means?
- The SEC has endorsed the offering price as fair to investors
- The SEC has approved the offering as a suitable investment
- The issuer may now sell the securities to the public; the SEC has neither approved the securities nor passed on the accuracy of the disclosures
- The SEC has verified that the information in the prospectus is accurate
Show answer and explanation
Answer: The issuer may now sell the securities to the public; the SEC has neither approved the securities nor passed on the accuracy of the disclosures
Under the Securities Act of 1933, the SEC enforces full and fair disclosure — it never performs merit review. When a registration statement becomes effective, the issuer is cleared to sell, but every prospectus must carry a disclaimer stating that the SEC has not approved or disapproved the securities and has not passed upon the accuracy or adequacy of the disclosures. Telling a customer a new issue is "SEC-approved" is a misrepresentation. The traps here are all versions of the same error: treating registration effectiveness as approval, verification, or endorsement of quality.
The Trap: SEC "approves" a new issue (registration effective mistaken for approval/endorsement)
- The SEC has endorsed the offering price as fair to investors: Merit-review misconception: the SEC does not evaluate or endorse pricing, quality, or fairness of any offering.
- The SEC has approved the offering as a suitable investment: The heavily tested "SEC approval" myth: the SEC uses a disclosure standard, not a merit standard, and does not judge whether a security is a good investment.
- The SEC has verified that the information in the prospectus is accurate: Verification misconception: the SEC reviews the filing for completeness of disclosure but does not certify or guarantee the accuracy or adequacy of the information.
Verified against: disclosure not merit)

Which statement BEST describes FINRA?
- The organization that registers and examines investment advisers
- A self-regulatory organization that, under SEC oversight, regulates broker-dealers and their associated persons
- A federal government agency that oversees all U.S. securities markets
- A nonprofit corporation that protects customer cash and securities when a brokerage firm fails
Show answer and explanation
Answer: A self-regulatory organization that, under SEC oversight, regulates broker-dealers and their associated persons
FINRA is a self-regulatory organization (SRO): a private-sector membership body funded by member fees that operates under SEC oversight, and its rules generally require SEC approval before they take effect. Its four core jobs are writing rules for broker-dealers, examining member firms, enforcing those rules (it can fine, suspend, bar, or expel — but it cannot imprison anyone; criminal cases are handled by the Department of Justice), and running arbitration for industry disputes; it also administers qualification exams such as the SIE. Investment advisers fall under the SEC or the states, and SIPC — not FINRA — protects customer assets if a broker-dealer fails.
The Trap: FINRA mistaken for a government agency (SRO vs. federal agency)
- The organization that registers and examines investment advisers: Jurisdiction misconception: investment advisers register with the SEC or state regulators, not FINRA — FINRA has no authority over firms that are purely advisers.
- A federal government agency that oversees all U.S. securities markets: SRO-vs-government confusion: FINRA is a private-sector membership organization funded by member fees, not a government agency — that description fits the SEC.
- A nonprofit corporation that protects customer cash and securities when a brokerage firm fails: FINRA-vs-SIPC confusion: custody protection in a broker-dealer liquidation is SIPC's role, not FINRA's.

Which statement accurately describes the Municipal Securities Rulemaking Board (MSRB)?
- It maintains its own examination staff that inspects and disciplines municipal securities dealers
- It writes rules for municipal securities dealers and municipal advisors but does not examine firms or enforce those rules itself
- It is a federal government agency with the power to prosecute municipal bond fraud
- It regulates municipal issuers, including reviewing the disclosures in their bond offerings
Show answer and explanation
Answer: It writes rules for municipal securities dealers and municipal advisors but does not examine firms or enforce those rules itself
Think of the MSRB, established by Congress in 1975, as a legislature with no police force. It writes the rules that govern municipal securities dealers, bank dealers, and municipal advisors, but it has no examination or enforcement staff — compliance is enforced by FINRA (for member broker-dealers), the SEC, or federal bank regulators (for bank dealers). Just as important: the MSRB does not regulate municipal issuers themselves, whose securities are exempt from 1933 Act registration. And as a self-regulatory organization, it is not a government agency and has no criminal prosecution power.
The Trap: MSRB enforces its own rules (it writes rules but does not examine or enforce)
- It maintains its own examination staff that inspects and disciplines municipal securities dealers: The classic MSRB trap: students assume a rulemaker also polices its rules. The MSRB has no examination or enforcement staff.
- It is a federal government agency with the power to prosecute municipal bond fraud: SRO-vs-government confusion plus enforcement overreach: the MSRB is an SRO, and no SRO — or even the SEC — can criminally prosecute; criminal cases go to the Department of Justice.
- It regulates municipal issuers, including reviewing the disclosures in their bond offerings: Issuer misconception: municipal issuers (states, cities) are outside the MSRB's reach — the MSRB regulates the dealers and advisors in the market, not the governments issuing the bonds.
Verified against: does not regulate issuers)

A technology company preparing its initial public offering must file a registration statement with the SEC and deliver a prospectus to purchasers. These requirements are imposed by the:
- Investment Advisers Act of 1940
- Uniform Securities Act
- Securities Act of 1933
- Securities Exchange Act of 1934
Show answer and explanation
Answer: Securities Act of 1933
New issues live under the Securities Act of 1933, often called the "paper act": it requires issuers to register offerings with the SEC and deliver a prospectus so investors receive full and fair disclosure. The Securities Exchange Act of 1934 is the "people and places act" — it created the SEC and governs secondary-market trading, exchanges, and broker-dealers. The Investment Advisers Act of 1940 covers advisers, and the Uniform Securities Act is the template for state-level blue-sky laws, which operate alongside — not in place of — federal registration.
The Trap: Assigning new-issue registration to the 1934 Act (primary vs. secondary market acts)
- Investment Advisers Act of 1940: Act-name confusion: the Advisers Act governs the registration and conduct of investment advisers, not securities offerings.
- Uniform Securities Act: Federal-vs-state confusion: the Uniform Securities Act is the model for state blue-sky laws. State registration is a separate, parallel layer — it is not the source of the federal registration-statement and prospectus requirements.
- Securities Exchange Act of 1934: The 1933-vs-1934 flip: the 1934 Act governs the secondary market — exchanges, broker-dealers, and trading — not the registration of new issues.

Which regulator is correctly paired with one of its responsibilities?
- MSRB — conducting compliance examinations of municipal securities dealers
- FINRA — administering qualification examinations and maintaining registration records of broker-dealer personnel
- Department of the Treasury — setting initial margin requirements on securities purchases
- SEC — reimbursing customers for cash and securities missing when a broker-dealer fails
Show answer and explanation
Answer: FINRA — administering qualification examinations and maintaining registration records of broker-dealer personnel
FINRA is the registration and testing hub for broker-dealer personnel: it administers qualification examinations such as the SIE and maintains registration and disciplinary records through the Central Registration Depository (CRD), which also feeds BrokerCheck. The wrong pairings each embody a common mix-up: the MSRB writes municipal rules but never examines or enforces (FINRA, the SEC, and bank regulators do that); initial margin comes from the Federal Reserve Board under Regulation T, not the Treasury; and reimbursing customers of a failed broker-dealer is SIPC's job under the Securities Investor Protection Act of 1970 — the SEC oversees markets but does not pay claims.
The Trap: Who-regulates-what mapping errors (MSRB examines / Treasury sets margin / SEC reimburses)
- MSRB — conducting compliance examinations of municipal securities dealers: MSRB-enforces misconception: the MSRB writes rules for municipal dealers but has no examination staff; FINRA, the SEC, and bank regulators examine and enforce.
- Department of the Treasury — setting initial margin requirements on securities purchases: Treasury-vs-Fed confusion: initial margin is set by the Federal Reserve Board under Regulation T; the Treasury issues federal government debt.
- SEC — reimbursing customers for cash and securities missing when a broker-dealer fails: SEC-vs-SIPC confusion: custody protection in a broker-dealer liquidation comes from SIPC, a nonprofit membership corporation — regulators do not reimburse customers.

A firm's only business is providing investment advice to clients for an annual fee based on a percentage of assets under management, and it manages approximately $500 million. With which regulator does this firm register?
- The SEC, as an investment adviser under the Investment Advisers Act of 1940
- The MSRB
- FINRA, because any firm in the securities business must become a FINRA member
- The securities administrator of its home state
Show answer and explanation
Answer: The SEC, as an investment adviser under the Investment Advisers Act of 1940
A firm paid for advice — typically a fee based on assets under management — is an investment adviser governed by the Investment Advisers Act of 1940, owing clients a fiduciary duty. Advisers generally register with the SEC once assets under management reach about $100 million; smaller advisers register with state securities regulators. FINRA regulates broker-dealers, which earn commissions and markups on transactions — it has no jurisdiction over a firm that only gives advice. The adviser-vs-broker-dealer split (fee/fiduciary/SEC-or-state versus commission/FINRA) is one of the most reliable regulator-mapping distinctions on the exam.
The Trap: FINRA regulates investment advisers (it regulates broker-dealers only)
- The MSRB: Jurisdiction mapping error: the MSRB writes rules for municipal securities dealers and municipal advisors to issuers — it has nothing to do with registering investment advisers.
- FINRA, because any firm in the securities business must become a FINRA member: The FINRA-regulates-everyone misconception: FINRA's jurisdiction covers broker-dealers and their associated persons, not firms engaged purely in investment advice.
- The securities administrator of its home state: SEC-vs-state split error: smaller advisers generally register with states, but at roughly $100 million or more under management an adviser registers with the SEC — $500 million is well past that line.

A customer buys $20,000 of listed stock in a margin account and is required to deposit at least 50% of the purchase price. Which regulator sets this initial margin requirement?
- The SEC
- The Department of the Treasury
- FINRA
- The Federal Reserve Board, under Regulation T
Show answer and explanation
Answer: The Federal Reserve Board, under Regulation T
Margin is fundamentally about credit, so Congress handed it to the nation's central bank: the Federal Reserve Board's Regulation T sets the initial margin requirement — currently 50% of the purchase price — for securities bought on credit through broker-dealers. FINRA layers its own maintenance requirements on top for ongoing positions, which is why students often misattribute the initial deposit to FINRA. The SEC polices markets and disclosure rather than credit, and the Treasury borrows for the government — neither sets margin. Remember the pairing: Regulation T = Federal Reserve = 50% initial.
The Trap: Attributing Regulation T initial margin to the SEC or FINRA instead of the Federal Reserve Board
- The SEC: The everything-is-the-SEC misconception: although the SEC oversees securities markets broadly, credit on securities purchases is controlled by the Federal Reserve, not the SEC.
- The Department of the Treasury: Treasury-vs-Fed confusion: the Treasury issues federal government debt and houses the IRS; it does not regulate credit extended for securities purchases.
- FINRA: Initial-vs-maintenance confusion: FINRA imposes ongoing maintenance-margin rules on member firms, but the initial 50% deposit requirement comes from the Federal Reserve Board under Regulation T.

A registered representative has passed the SIE and the Series 7. Before she may solicit securities business from residents of her state, her firm requires her to pass the Series 63. This additional requirement exists because:
- The MSRB requires the exam before anyone may sell municipal bonds
- State blue-sky laws require agents to register at the state level, a system separate from federal and FINRA registration
- The SEC requires agents to register federally in each state where they conduct business
- FINRA rules require every registered representative to pass an additional state-law examination
Show answer and explanation
Answer: State blue-sky laws require agents to register at the state level, a system separate from federal and FINRA registration
U.S. securities regulation runs on two parallel tracks: federal (the SEC, plus FINRA for broker-dealers) and state "blue-sky" laws modeled on the Uniform Securities Act, which generally require agents and many securities to be registered in each state where business is done. NASAA — the North American Securities Administrators Association, the organization of state regulators — creates the content of the state-law exams (Series 63, 65, and 66). Passing federal-track exams does not by itself satisfy the state layer, and state antifraud authority applies even to securities that are exempt from registration.
The Trap: Treating state blue-sky registration as a FINRA or SEC requirement (dual federal/state system)
- The MSRB requires the exam before anyone may sell municipal bonds: Exam-mapping error: the Series 63 is a state-law exam; it is not an MSRB municipal-securities qualification.
- The SEC requires agents to register federally in each state where they conduct business: Dual-system confusion: the SEC operates the federal layer; it does not run state-by-state registration of agents — the states themselves do.
- FINRA rules require every registered representative to pass an additional state-law examination: Misattributing the state layer to FINRA: the Series 63 obligation flows from state law, not from FINRA registration requirements.

Which statement correctly describes the division of responsibilities between the U.S. Treasury and the Federal Reserve?
- The Federal Reserve both issues government securities and conducts monetary policy
- The Treasury issues bills, notes, and bonds to finance the federal government; the Federal Reserve conducts monetary policy, including buying and selling Treasury securities in the open market
- The Federal Reserve issues Treasury bills, notes, and bonds; the Treasury sets interest-rate policy
- The Treasury conducts monetary policy through the FOMC; the Federal Reserve collects federal taxes
Show answer and explanation
Answer: The Treasury issues bills, notes, and bonds to finance the federal government; the Federal Reserve conducts monetary policy, including buying and selling Treasury securities in the open market
Keep the two roles straight: the Treasury borrows, the Fed steers. The Department of the Treasury issues bills, notes, and bonds to finance the federal government (and houses the IRS, which enforces the tax code). The Federal Reserve is the central bank: through the FOMC it conducts monetary policy, most visibly by buying and selling already-issued Treasury securities in open market operations — buying injects money into the banking system, selling drains it. The Fed does not issue Treasury securities, and the Treasury does not set monetary policy — flipping those roles is the classic error tested here.
The Trap: Believing the Federal Reserve issues Treasury securities (Treasury vs. Fed role reversal)
- The Federal Reserve both issues government securities and conducts monetary policy: The documented "Fed issues Treasuries" misconception: the Fed trades existing government securities in open market operations (and acts as auction agent) but does not issue them — the Treasury does.
- The Federal Reserve issues Treasury bills, notes, and bonds; the Treasury sets interest-rate policy: A complete role reversal — the flip version of the correct answer that catches students who memorized the pairing without the direction.
- The Treasury conducts monetary policy through the FOMC; the Federal Reserve collects federal taxes: Monetary-vs-fiscal scramble: the FOMC is a Federal Reserve body, and tax collection belongs to the IRS, a bureau of the Treasury — not to the Fed.
Verified against: Fed conducts monetary policy; Fed does not issue Treasuries)
What the SIE tests here
This topic sits in Section 1: Knowledge of Capital Markets, 16% of the exam, 12 of the 75 scored questions. The testable material is a pyramid. At the top: the SEC, a federal government agency created by the Securities Exchange Act of 1934. Below it: the self-regulatory organizations it oversees: FINRA, the MSRB, CBOE, and the exchanges. Below them: member firms and their associated persons. Most questions hand you a job description (“writes rules for municipal securities dealers”) and ask who owns it.
The three traps that do the damage
“The SEC approved the new issue.” It never does. The SEC clears a registration under the Securities Act of 1933. It forces full and fair disclosure and never judges investment merit. The mandatory prospectus disclaimer says exactly this, and it’s a near-guaranteed distractor.
“The MSRB enforces its rules.” It doesn’t. The MSRB writes rules for municipal securities dealers and municipal advisors but has no examination or enforcement staff: FINRA, the SEC, and bank regulators do the policing. Think of it as a legislature with no police force. Related trap: the MSRB does not regulate municipal issuers at all.
“FINRA is a government agency.” It’s a membership SRO operating under SEC oversight. It can fine, suspend, bar, or expel; it cannot imprison anyone (criminal matters go to the Department of Justice). And it regulates broker-dealers, not investment advisers; advisers register with the SEC or the states.
How these questions teach
Each explanation restates the concept in plain English, names the trap you were steered toward, and ends with the source it was verified against: the 1933 Act, the 1934 Act, or the specific FINRA or MSRB rule (all 29 items current as of July 2026).
