CFA Institute Level I curriculum — 10 topic areas: Ethics, Quantitative Methods, Economics, Financial Statement Analysis, Corporate Issuers, Equity Investments, Fixed Income, Derivatives, Alternative Investments, Portfolio Management
CoStudy's CFA Level I bank holds 702 items organised into 10 chapters that follow the published blueprint. Every multiple-choice question carries a written rationale explaining why the correct answer is correct and why each distractor is tempting but wrong, and the bank includes 10 scenario-based simulations.
Each chapter follows a domain of the published exam outline. Practise one on its own:
A sample of 24 multiple-choice questions from the bank, with the full rationale shown.
An investment doubles in 9 years. Approximate annualized return using the Rule of 72?
Answer: C — 8.0%
A) Wrong divisor — 72/14.4 ~ 5. B) Uses 65/9 or dividing years by 9 — off. C) Correct — 72 / 9 = 8%. D) Confuses years with the rate itself.
For a normal distribution, approximately what percentage of observations fall within ±2 standard deviations of the mean?
Answer: D — 95 percent, the empirical-rule interval bounded by roughly ±2 standard deviations on each side
A) That figure describes the ±1σ interval, not ±2σ. B) The 50% figure describes the interquartile range instead. C) That figure describes the ±3σ interval. D) Correct — the 68/95/99.7 empirical rule places 95.4% within ±2σ.
Algorithmic trading is best defined as trading that is characterized by which of the following operational features?
Answer: A — Executed by computer programs following predefined rules on timing, price, and quantity of orders sent to the market
A) Correct — algorithmic trading is rule-based computer execution. B) Algorithmic trading spans all liquid markets. C) Manual chart-based trading is the opposite of algorithmic.
Demand-pull inflation MOST often results from:
Answer: A — Aggregate demand exceeding the productive capacity
A) Correct — AD above full-employment AS pulls prices upward. B) Describes cost-push, not demand-pull, inflation. C) Money contraction is disinflationary, not inflationary. D) Higher productivity typically eases price pressures.
The Mundell-Fleming framework suggests that a country with free capital mobility CANNOT simultaneously maintain:
Answer: C — A fixed exchange rate and independent monetary policy
A) Stable prices are not part of the trilemma constraint. B) Balanced budgets belong to fiscal policy, not the trilemma. C) Correct — the impossible trinity forbids fixed FX, free capital, and independent policy together. D) Both are consistent components, not incompatible.
Nominal GDP grew 5% and the GDP deflator rose 3%. Real GDP growth was approximately:
Answer: C — 2% from subtracting inflation from nominal growth
A) Adding the two inflates real growth artificially. B) Multiplication of percentages has no economic meaning here. C) Correct — real growth ≈ nominal growth − inflation ≈ 5% − 3% = 2%. D) Halving has no economic basis in the deflator identity.
Working capital is:
Answer: D — Current assets minus current liabilities
A) Confuses long-term with short-term measures. B) Working capital is a balance-sheet figure, not profit. D) Correct — standard net working capital formula. C) Inventory is only one component, not the total.
A 'poison pill' is a corporate-governance device that:
Answer: D — Lets shareholders buy discounted shares if threatened
D) Correct — shareholder rights plans dilute hostile bidders crossing a threshold. B) Describes proxy access, not a poison pill. C) Say-on-pay and clawbacks address compensation. A) Insider-trading rules address executive share sales.
A firm's degree of operating leverage (DOL) measures sensitivity of:
Answer: D — Operating income to a change in unit sales
A) Tax sensitivity is not what DOL captures. B) That is degree of financial leverage (DFL). C) Stock-price sensitivity relates to beta and required return. D) Correct — DOL = %ΔEBIT / %ΔSales, driven by fixed operating costs.
Commercial mortgage-backed securities (CMBS) differ from residential MBS in that CMBS typically exhibit which of the following contractual and structural features?
Answer: B — Restrict prepayment through lockouts, defeasance requirements, prepayment penalties, and yield-maintenance provisions in the underlying loan documentation
A) Residential MBS carries more prepayment risk than CMBS. B) Correct — CMBS contractually reduces prepayment optionality. C) CMBS is not federally guaranteed.
Under IFRS 16, a lessee's right-of-use asset is amortized over the:
Answer: C — Shorter of lease term or asset useful life
A) Ignores lease-term limit. B) Includes uncommitted renewal options. C) Correct — IFRS 16 uses the shorter of the two periods. D) Reverses the correct rule.
Return on equity (ROE) under DuPont decomposition equals:
Answer: D — Profit margin times turnover times leverage
A) Wrong denominator entirely. B) Not a standard ratio. C) Correct as simple ROE, but not the DuPont decomposition. D) Correct — three-factor DuPont identity.
Private equity investments are MOST likely characterized by:
Answer: D — Long lockups, J-curve returns, and use of fund leverage
A) Public equities, not PE, have daily liquidity and low fees. B) Illiquid holdings are valued periodically, not continuously. D) Correct — PE features illiquidity, J-curve, leverage, and 2/20 fee economics. C) Passive index tracking is a public-market strategy.
A firm with sustainable ROE of 15% and a retention ratio of 60% has a sustainable growth rate of:
Answer: C — 9% sustainable growth rate per year
A) Uses ROE × payout instead of ROE × retention. B) Uses ROE alone with no retention adjustment. C) Correct — g = ROE × b = 0.15 × 0.60 = 9%. D) Uses ROE/retention ratio incorrectly.
A yield curve that slopes downward (long-term yields below short-term) is BEST associated with:
Answer: C — Falling future short rates preceding an economic slowdown
A) Describes a normal upward-sloping curve. B) Describes concurrent policy action, not curve shape. C) Correct — inverted curves signal expected rate cuts and often precede recessions. D) Flat, not inverted, curves imply stability.
A bond's credit spread reflects compensation for:
Answer: D — Default risk, loss given default, and risk premium
A) The risk-free rate is the benchmark subtracted, not the spread. B) Currency risk applies to FX-denominated bonds, distinct from credit spread. C) Inflation is embedded in the benchmark rate, not the spread. D) Correct — credit spread compensates for default probability, LGD, liquidity, and risk premium.
A call option gives the holder the right, but not the obligation, to:
Answer: C — Buy an asset at the specified strike price
A) That describes a put option. B) That describes an FX spot transaction. C) Correct — call gives the right to buy at strike. D) Options don't carry dividend rights.
In a one-period binomial option model, the call is priced using:
Answer: C — Risk-neutral probabilities and the risk-free rate
A) The real-world probability is not the pricing measure. B) Preferences vanish under no-arbitrage pricing. C) Correct — π = (R−d)/(u−d), discount at Rf. D) That is the discounted expected value under CAPM instead.
A private-equity fund's 'J-curve' return pattern reflects:
Answer: A — Early negative returns then later exit gains
A) Correct — fees and early markdowns depress NAV first. B) Constant returns are not the J-curve pattern. C) That inverts the actual timing of distributions. D) That would be an inverted or failed-fund pattern.
A commodity futures investor experiences 'contango' when:
Answer: A — Futures prices exceed spot, creating negative roll yield
A) Correct — an upward-sloping curve where futures > spot; rolling into more expensive contracts drags returns. B) The reverse pattern is backwardation, which produces positive roll yield. C) Zero basis is a coincidence, not the definition of contango. D) Flat curves reflect equal storage and convenience yield.
Sharpe ratio:
Answer: D — Excess return per unit of total risk
A) Ignores the risk denominator. B) Ignores the return numerator. C) Ignores both risk and Rf. D) Correct — (Rp − Rf) / sigma, higher is better.
Representativeness bias leads investors to make which of the following systematic errors when they judge probabilities of outcomes?
Answer: A — Judge probabilities by how closely a specific case matches a familiar stereotype, systematically neglecting the underlying base-rate information
A) Correct — representativeness relies on stereotypes and neglects base rates. B) That describes anchoring bias. C) Infrequent trading is unrelated to representativeness.
A research analyst issues a 'Buy' recommendation on a stock. Her firm makes a market in the same security and earned investment-banking fees from the issuer last year. Under Standard VI(A), the published report must:
Answer: B — Prominently disclose the market-making and banking relationships so that readers can assess any potential bias
A) Independent judgment does not eliminate the firm-level conflict-disclosure duty. B) Correct — prominent disclosure allows a reasonable investor to weigh potential bias. C) VI(A) requires disclosure, not suppression.

6 sample cards from the 291 in the bank.
What is Standard III(A) 'Loyalty, Prudence, and Care'?
Members must act for the benefit of clients and place client interests before employer or personal interests.
What are the three main financial statements?
Income Statement (profitability), Balance Sheet (financial position), Cash Flow Statement (cash inflows/outflows).
What is the degree of financial leverage (DFL)?
% Change in EPS / % Change in EBIT. Measures how sensitive EPS is to changes in operating income.
What is the bid-ask spread?
The difference between the highest price a buyer will pay (bid) and the lowest price a seller will accept (ask). A measure of liquidity — narrower is more liquid.
What is deferred revenue?
Cash received before earning it (a liability). As the service/product is delivered, deferred revenue is recognized as earned revenue.

These samples are a small slice. The full bank runs flashcards, multiple choice and timed mock exams with per-chapter progress tracking, on the web and in the iOS app.
The CFA Level I bank holds 702 items: 401 multiple-choice questions, 291 flashcards and 10 scenario-based simulations. 30 of them are on this page to read free, with no signup.
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.
It is organised into 10 chapters that follow the published exam blueprint: Quantitative Methods; Economics; Corporate Issuers; Financial Statement Analysis; Equity Investments; Fixed Income; Derivatives; Alternative Investments; Portfolio Management; Ethical and Professional Standards. 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.

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.
This bank is written against CFA Institute's published exam material. Check the CFA Program curriculum for the current outline, fees and eligibility rules — those change, and the certifying body is the only authority on them. CoStudy is not affiliated with CFA Institute.
