Quantitative Methods, Statistics, and Risk Foundations flashcards for Chartered Alternative Investment Analyst (CAIA)

24 of 51 cards from the Quantitative Methods, Statistics, and Risk Foundations deck — real questions with worked answers.

1. What is the formula for a simple (holding period) return over a single period?

   R = (P_end - P_begin + CashFlow) / P_begin. It expresses the gain/loss plus income as a fraction of the beginning value.

2. How does a log (continuously compounded) return differ from a simple return, and what is its formula?

   Log return = ln(P_end / P_begin). Unlike simple returns, log returns are additive across time (sum of log returns = total log return) but not across assets in a portfolio.

3. What is a gross return versus a net return?

   Gross return is the total return including the original principal (e.g., 1 + R, or value relative). Net return is the gain only, excluding the principal (R itself, often after fees).

4. Distinguish nominal return from real return.

   Nominal return is the stated return unadjusted for inflation. Real return adjusts for inflation: (1 + real) = (1 + nominal)/(1 + inflation), approximately real ≈ nominal − inflation.

5. What is the difference between an arithmetic mean return and a geometric mean return?

   Arithmetic mean is the simple average of periodic returns; geometric mean is the compounded average: [(1+R1)...(1+Rn)]^(1/n) − 1. Geometric is always ≤ arithmetic and reflects actual multi-period growth.

6. What does a money-weighted return (IRR) measure?

   The money-weighted return is the internal rate of return that sets the present value of all cash inflows and outflows (including contributions and withdrawals) equal to zero. It reflects the actual dollar-weighted experience of the investor.

7. What does a time-weighted return measure?

   The time-weighted return measures the compound growth of one unit of currency invested over the period, neutralizing the effect of the timing and size of external cash flows by linking sub-period returns geometrically.

8. When does the money-weighted return exceed the time-weighted return?

   When the investor adds capital before a period of strong performance (good timing) or withdraws before poor performance. Larger amounts invested during high-return periods raise the money-weighted return above the time-weighted return.

9. Why is the time-weighted return preferred for evaluating a portfolio manager?

   Because the manager usually does not control the timing or size of client cash flows; the time-weighted return removes that distortion, isolating the manager's investment skill.

10. How is a time-weighted return computed when there are interim cash flows?

    Break the total period into sub-periods at each cash flow, compute each sub-period's holding period return, then geometrically link them: TWR = (1+R1)(1+R2)...(1+Rn) − 1.

11. What is a probability density function (PDF) of returns?

    A function f(r) describing the relative likelihood of a continuous return taking a given value; the area under f(r) over an interval gives the probability the return falls in that interval, and the total area equals 1.

12. In return notation, what do E[R] and σ(R) represent?

    E[R] is the expected (mean) return of the distribution; σ(R) is the standard deviation of returns, a measure of dispersion/volatility around the mean.

13. What is an ex ante versus ex post return distribution?

    Ex ante is the forward-looking, anticipated distribution based on expectations/probabilities. Ex post is the realized, historical distribution observed from past data.

14. What are the four central moments of a return distribution?

    1st: mean (location). 2nd: variance/standard deviation (dispersion). 3rd: skewness (asymmetry). 4th: kurtosis (tail thickness/peakedness).

15. What does positive (right) skewness imply about returns?

    A long right tail: frequent small losses or modest returns with occasional large positive outliers. Mean > median. Investors generally prefer positive skewness.

16. What does negative (left) skewness imply, and why is it concerning for alternatives?

    A long left tail: frequent small gains with occasional large losses. Mean < median. Many alternative strategies (e.g., selling options, carry, credit) exhibit negative skew, hiding large downside risk.

17. What is kurtosis, and what is excess kurtosis?

    Kurtosis measures the thickness of the tails (4th standardized moment). Excess kurtosis = kurtosis − 3 (since a normal distribution has kurtosis of 3). Positive excess kurtosis = leptokurtic = fat tails.

18. What is a leptokurtic distribution and why does it matter for alternatives?

    A leptokurtic distribution has excess kurtosis > 0, meaning fatter tails and a higher peak than normal. Alternative investments often display fat tails, so extreme outcomes occur more often than a normal model predicts.

19. How is variance of returns calculated from a sample?

    Sample variance = Σ(Ri − R̄)² / (n − 1), where R̄ is the sample mean. Standard deviation is its square root. The (n−1) denominator gives an unbiased estimate.

20. Why is normality often a poor assumption for alternative investment returns?

    Alternative returns frequently exhibit non-normality: skewness, excess kurtosis (fat tails), serial correlation, and illiquidity-driven smoothing, so mean-variance metrics understate true risk.

21. How can return smoothing (stale pricing) distort reported alternative-asset statistics?

    Infrequent or appraisal-based valuations smooth returns, artificially lowering reported volatility and correlations and inducing positive autocorrelation, making the asset look less risky and more diversifying than it is.

22. What is the formula for covariance between two assets' returns?

    Cov(X,Y) = E[(X − E[X])(Y − E[Y])], estimated as Σ(Xi − X̄)(Yi − Ȳ)/(n − 1). It measures how two return series move together; units are squared returns.

23. How is the correlation coefficient defined in terms of covariance?

    ρ(X,Y) = Cov(X,Y) / (σX · σY). It is a standardized, unitless measure of linear co-movement bounded between −1 and +1.

24. What is autocorrelation (serial correlation) of returns?

    The correlation of a return series with its own lagged values. Positive first-order autocorrelation means high returns tend to follow high returns; it often signals illiquidity or return smoothing in alternatives.
