Economic Factors and Business Information

Which of the following is classified as a LAGGING economic indicator?

  1. Average duration of unemployment among unemployed workers
  2. New building permits issued for private housing units
  3. Average weekly hours worked in manufacturing industries
  4. The spread between long-term and short-term Treasury yields

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:

  1. A rapid economic expansion with substantial near-term investor gains
  2. A likely transition point where the economic outlook is uncertain
  3. A confirmed recession that has already begun across all sectors
  4. No relationship at all between economic activity and interest rates

Answer: B — A likely transition point where the economic outlook is uncertain

A) More consistent with a steep, normal curve. B) Correct — flat curves often mark a transition point. C) 'Confirmed' overstates the signal — it's not a confirmed recession. D) Yield curve shape does relate to growth expectations.

Investment Vehicle Characteristics

A key risk of private equity investing that distinguishes it from publicly traded equity is:

  1. Daily mark-to-market pricing that creates excessive short-term volatility
  2. Illiquidity, since capital is typically locked up for years with limited exit options
  3. Mandatory quarterly dividend distributions required under private fund rules
  4. 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?

  1. Series of derivative contracts settled daily through a central clearing counterparty
  2. Equity ownership in a portfolio of stocks held by a registered investment company
  3. Pass-through certificate representing an undivided interest in real estate assets
  4. 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:

  1. Carries no dividend but a share in unlimited earnings growth of the issuer over time
  2. Carries voting rights on all matters submitted to the shareholders for a formal vote
  3. Carries a fixed dividend rate and priority over common stock in liquidation payouts
  4. 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:

  1. The time a fund manager must wait before charging a performance fee
  2. The interval between a fund's initial offering and its first NAV calculation
  3. A minimum holding period during which investors cannot redeem their investment
  4. 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:

  1. Equivalent duration because both securities share the same stated final maturity date
  2. Lower duration and therefore lower price sensitivity to changes in market yields
  3. Higher duration and therefore greater price sensitivity to changes in market yields
  4. 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?

  1. 100% laddered investment-grade bond portfolio with no equity or inflation-linked component
  2. 100% money market fund to eliminate volatility and preserve principal for daily needs
  3. Diversified mix of investment-grade bonds, TIPS, and dividend-paying equities
  4. 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:

  1. Expected return equals the market return divided by the security's beta coefficient value
  2. Expected return equals the risk-free rate multiplied by the security's beta coefficient
  3. Expected return equals beta times the market return minus the standard deviation value
  4. 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:

  1. Curve traced by the efficient frontier of all-risky-asset portfolios in mean-variance space
  2. Straight line connecting individual stock expected returns as a function of each stock's beta
  3. Straight line from the risk-free rate tangent to the efficient frontier at the market portfolio
  4. 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:

  1. Reflects the stated tolerance because the client has expressed clear willingness to bear risk
  2. Averages tolerance and capacity to split the difference between the client's inputs
  3. Reflects the lower of tolerance and capacity because both must align for suitability
  4. 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?

  1. Total portfolio standard deviation to capture both systematic and unsystematic risk
  2. Tracking error against a benchmark index to capture active management risk taken
  3. Portfolio beta to capture only systematic (nondiversifiable) risk of the portfolio
  4. 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:

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:

Series 66 flashcards

6 sample cards from the 250 in the bank.

What is tactical asset allocation?

Short-term active deviations from strategic targets to exploit perceived opportunities. Requires market-timing skill; higher costs.

Series 66 — frequently asked

How many Series 66 practice questions does CoStudy have?

The Series 66 bank holds 532 items: 260 multiple-choice questions, 250 flashcards and 22 scenario-based simulations. 26 of them are on this page to read free, with no signup.

Do the Series 66 questions come with explanations?

Yes. Every multiple-choice item carries a written rationale that states the controlling principle behind the correct answer and then addresses each wrong option in turn — why it tempts and precisely where it fails. Knowing why the plausible answer was wrong is worth more than knowing which letter was right.

What topics does the Series 66 bank cover?

It is organised into 4 chapters that follow the published exam blueprint: Economic Factors and Business Information; Investment Vehicle Characteristics; Client Investment Recommendations and Strategies; Laws, Regulations, and Guidelines, Including Prohibition on Unethical Business Practices. The number of questions in each chapter is proportional to that domain's published weight, so working through the bank exposes you to roughly the mix the real exam uses.

How current is the Series 66 content?

Last reviewed 2026-08-22. Banks are written against the certifying body's published exam outline and re-checked when that outline changes — exams get renumbered, retired and reweighted, and a bank written to a superseded outline teaches the wrong proportions. Figures that are re-indexed annually are deliberately not asserted as rules; the questions test the governing principle instead.
