Series 66 — FINRA practice for the NASAA Uniform Combined State Law Exam
Series 66 is the NASAA Uniform Combined State Law Exam. FINRA writes the outline; a fail is another sitting fee and a delayed start, not a school-curve disappointment. Related CoStudy banks (finra_sie, series_6, series_7, series_63) test different sittings — using one as a stand-in for Series 66 is how people fail the appointment they paid for.
CoStudy’s Series 66 bank holds 260 multiple-choice questions, 250 flashcards and 22 scenario simulations. Chapters in this bank follow that outline: Economic Factors and Business Information; Investment Vehicle Characteristics; Client Investment Recommendations and Strategies; Laws, Regulations, and Guidelines, Including Prohibition on Unethical Business Practices. The published material this bank is written against begins: NASAA Series 66 (Uniform Combined State Law) public exam content outline — combining Series 63 + 65 topics. Domains: Economic Factors & Business Information (5%), Investment Vehicle Characteristics (20%), Client Recommendations & Strategies (30%), Laws, Regulations & Guidelines… Every multiple-choice item on this page shows the full rationale in the HTML. CoStudy is not FINRA. We do not have live items, and we do not guarantee a result.

How this bank is different
- Series 66 is a registration exam with a job-function outline. Product trivia without a customer file is the wrong sport.
- Distractors are usually legal products that fail one constraint in the profile.
- SIE vocabulary is not a substitute for the qualification exam your firm actually filed.

Study timeline
Most Series 66 candidates have a sponsor clock, not a sabbatical. Plan from the published job functions, not from a product glossary.
Six-week Series 66 block — 10–14 hours/week
Weeks 1–4: walk the chapters in outline order, with a mixed set twice a week. Week 5: only the two weakest chapters. Week 6: two timed sittings in the shape the certifying body describes, then stop adding new outline. Series 66 samples on this page are for judging rationale quality, not for a full mock.
Twelve-week working-hours plan — 6–8 hours/week
Two or three evenings and one weekend block. Keep a written error log keyed to chapters, not to “I was tired.” The last fourteen days are timing and weak-chapter repair only. If you are also sitting a related exam (finra_sie), do not merge the decks.
Free Series 66 practice questions
A sample of 20 multiple-choice questions from the bank, with the full rationale shown.
Economic Factors and Business Information
Which of the following is classified as a LAGGING economic indicator?
- Average duration of unemployment among unemployed workers
- New building permits issued for private housing units

Answer: A — Average duration of unemployment among unemployed workers
A) Correct — average duration of unemployment lags the cycle. B) Leading indicator. C) Leading indicator. D) Leading indicator (yield spread).
A flat yield curve, where short- and long-term yields converge, is BEST interpreted as signaling:
- A rapid economic expansion with substantial near-term investor gains

A) Monetary. B) Monetary (Fed Board). C) Monetary (OMO). D) Correct — fiscal is Congress + Treasury.
Investment Vehicle Characteristics
A key risk of private equity investing that distinguishes it from publicly traded equity is:
- Daily mark-to-market pricing that creates excessive short-term volatility
- Illiquidity, since capital is typically locked up for years with limited exit options
- Mandatory quarterly dividend distributions required under private fund rules
- Guaranteed capital preservation due to the limited partnership structure
Answer: B — Illiquidity, since capital is typically locked up for years with limited exit options
A) Private equity lacks daily mark-to-market pricing — the opposite issue. B) Correct — long lockups and limited secondary markets are defining risks. C) No such mandatory distribution rule exists. D) No capital preservation guarantee exists.
An Exchange-Traded Note (ETN) is best characterized as which of the following instruments?
- Series of derivative contracts settled daily through a central clearing counterparty
- Equity ownership in a portfolio of stocks held by a registered investment company
- Pass-through certificate representing an undivided interest in real estate assets
- Unsecured debt of an issuing bank whose return tracks a specified reference index
Answer: D — Unsecured debt of an issuing bank whose return tracks a specified reference index
A) That's futures/swaps. B) That's an ETF/mutual fund. C) That's a REIT. D) Correct — ETN = senior unsecured note of a bank.
The characteristic that distinguishes preferred stock from common stock is that preferred typically:
- Carries no dividend but a share in unlimited earnings growth of the issuer over time
- Carries voting rights on all matters submitted to the shareholders for a formal vote
- Carries a fixed dividend rate and priority over common stock in liquidation payouts
- Carries a junior claim below common stock in the event of the issuer's liquidation
Answer: C — Carries a fixed dividend rate and priority over common stock in liquidation payouts
A) That's common. B) Preferred usually lacks voting. C) Correct. D) Reverses the priority.
A hedge fund's 'lockup period' refers to:
- The time a fund manager must wait before charging a performance fee
- The interval between a fund's initial offering and its first NAV calculation
- A minimum holding period during which investors cannot redeem their investment
- A regulatory waiting period before the fund may begin trading securities
Answer: C — A minimum holding period during which investors cannot redeem their investment
A) Not related to performance fee timing. C) Correct — lockups restrict early redemption by investors. B) Not what a lockup period means. D) Not a regulatory trading restriction.
A zero-coupon Treasury bond compared to a coupon Treasury with the same maturity typically exhibits:
- Equivalent duration because both securities share the same stated final maturity date
- Lower duration and therefore lower price sensitivity to changes in market yields
- Higher duration and therefore greater price sensitivity to changes in market yields
- Zero duration because there are no interim coupon payments to weight in the calculation
Answer: C — Higher duration and therefore greater price sensitivity to changes in market yields
A) Coupons reduce duration. B) Reverses. C) Correct — zeros have duration equal to maturity, the maximum. D) Duration is not zero; it equals maturity for a zero-coupon.
Client Investment Recommendations and Strategies
A retiree needing steady income, low volatility, AND inflation protection over 20 years should generally receive which allocation approach?
- 100% laddered investment-grade bond portfolio with no equity or inflation-linked component
- 100% money market fund to eliminate volatility and preserve principal for daily needs
- Diversified mix of investment-grade bonds, TIPS, and dividend-paying equities
- 100% growth equity portfolio to maximize long-term real return over the horizon
Answer: C — Diversified mix of investment-grade bonds, TIPS, and dividend-paying equities
A) Half-right — no inflation protection or equity. B) Cash loses to inflation. C) Correct — hits all three goals. D) Too much volatility for a retiree.
The Capital Asset Pricing Model's expected return formula is expressed as:
- Expected return equals the market return divided by the security's beta coefficient value
- Expected return equals the risk-free rate multiplied by the security's beta coefficient
- Expected return equals beta times the market return minus the standard deviation value
- Expected return equals risk-free rate plus beta times the equity risk premium value
Answer: D — Expected return equals risk-free rate plus beta times the equity risk premium value
A) Wrong. B) Wrong operation. C) Wrong. D) Correct — E(R) = Rf + β(Rm − Rf).
The Capital Market Line (CML) is best described as:
- Curve traced by the efficient frontier of all-risky-asset portfolios in mean-variance space
- Straight line connecting individual stock expected returns as a function of each stock's beta
- Straight line from the risk-free rate tangent to the efficient frontier at the market portfolio
- Line showing the total return of the aggregate stock market over the historical measurement period
Answer: C — Straight line from the risk-free rate tangent to the efficient frontier at the market portfolio
A) Efficient frontier is a curve, not the CML. B) That's the Security Market Line. C) Correct. D) Not the CML.
When a client's stated risk tolerance is HIGH but risk capacity is LOW, the adviser should generally construct a portfolio that:
- Reflects the stated tolerance because the client has expressed clear willingness to bear risk
- Averages tolerance and capacity to split the difference between the client's inputs
- Reflects the lower of tolerance and capacity because both must align for suitability
- Reflects the higher of tolerance and capacity to maximize the client's long-run outcome
Answer: C — Reflects the lower of tolerance and capacity because both must align for suitability
A) Ignoring capacity is unsuitable. B) Averaging can still leave the client over-exposed. C) Correct — binding constraint is the lower. D) Reversed.
The Treynor ratio differs from the Sharpe ratio in that Treynor uses which measure in the denominator?
- Total portfolio standard deviation to capture both systematic and unsystematic risk
- Tracking error against a benchmark index to capture active management risk taken
- Portfolio beta to capture only systematic (nondiversifiable) risk of the portfolio
- Downside deviation to capture only losses below the risk-free rate minimum threshold
Answer: C — Portfolio beta to capture only systematic (nondiversifiable) risk of the portfolio
A) That's Sharpe. B) That's information ratio. C) Correct — Treynor uses beta. D) That's Sortino.
Laws, Regulations, and Guidelines, Including Prohibition on Unethical Business Practices
Custody under Investment Advisers Act Rule 206(4)-2 is generally deemed to exist when the adviser has:
- Direct or indirect access to client funds or securities, including the ability to deduct fees

- Any relationship with the client's qualified custodian involving joint bank references
- The right to exercise investment discretion over securities held at a qualified custodian
Answer: A — Direct or indirect access to client funds or securities, including the ability to deduct fees
A) Correct — custody = access. B) Discretion alone isn't custody. C) Wrong. D) Discretion without access ≠ custody.
A broker-dealer's obligation to maintain books and records such as order tickets, trade blotters, and customer account records exists primarily to:
- Provide regulators and the firm with an accurate, auditable record of customer activity
- Allow the firm to calculate its annual bonus pool for registered representatives
- Satisfy a purely voluntary industry best practice with no regulatory requirement
- Replace the need for any customer account statements to be sent periodically
Answer: A — Provide regulators and the firm with an accurate, auditable record of customer activity

An investment adviser may charge a performance-based fee to a retail client only if the client qualifies as a 'qualified client,' which generally requires:
- At least $1.1 million in assets under management with the adviser or $2.2 million net worth
- A minimum of $50,000 in assets under management with no net worth requirement
- Institutional status only, since no individual client may ever pay a performance fee
- A signed waiver of fiduciary duty protections filed with the state Administrator
Answer: A — At least $1.1 million in assets under management with the adviser or $2.2 million net worth
A) Correct — the current qualified-client thresholds, subject to periodic inflation adjustment. B) Understates the required threshold substantially. C) Individual clients CAN pay performance fees if they qualify. D) No such fiduciary-duty waiver mechanism exists.
Under the SEC's Marketing Rule (Rule 206(4)-1), an investment adviser using a client testimonial in its advertising must:
- Never use testimonials under any circumstance, since they remain absolutely prohibited
- Provide required disclosures about compensation and the relationship, and maintain related records
- Obtain testimonials only from clients who have never paid a fee to the adviser
