Series 65 Risk and Return Practice Questions

Correct answer: A. Default (credit) risk

High-yield bonds carry lower credit ratings, reflecting a greater likelihood that the issuer could default on interest or principal payments. The additional yield offered is compensation for this elevated default (credit) risk, not for interest rate movements or inflation.

• A. Correct. Junk bonds carry a higher risk of issuer default, so investors demand a higher yield (credit spread) to compensate for that added default risk.
• B. Interest rate risk affects all bonds similarly based on duration and is not the primary driver of the yield spread between junk and investment-grade bonds.
• C. Purchasing power (inflation) risk applies broadly across fixed income and isn't what distinguishes junk from investment-grade yields.
• D. Reinvestment risk relates to reinvesting coupon payments at prevailing rates and isn't the reason junk bonds carry higher yields than investment-grade bonds.

Correct answer: C. Unsystematic risk

Unsystematic risk (also called diversifiable or company/industry-specific risk) arises from factors unique to a single issuer or industry — a lawsuit, a product recall, a labor strike. Because these events are not correlated across all holdings, adding enough uncorrelated securities to a portfolio averages out these idiosyncratic shocks. Systematic risk and market risk (which are essentially the same thing — the risk inherent to the entire market, driven by factors like interest rates, inflation, and macroeconomic cycles) cannot be diversified away because they affect all securities simultaneously. Purchasing power risk is a subset of systematic risk and is similarly non-diversifiable.

• A. Systematic (market-wide) risk affects all securities and cannot be diversified away by adding more holdings — that's the risk diversification does not reduce.
• B. Purchasing power risk stems from inflation eroding real returns across the board; it is a systematic risk and is not reduced by spreading investments across companies and industries.
• C. Correct. Diversification across unrelated companies and industries primarily reduces unsystematic (company/industry-specific) risk, since those idiosyncratic risks tend to offset each other in a broad portfolio.
• D. Market risk is a form of systematic risk tied to overall market movements and is not reduced through diversification across securities.

Correct answer: D. Only about 20% of the fund's price movement is explained by movements in the S&P 500, so the fund's beta is not a meaningful indicator of its risk relative to that benchmark

R-squared measures the percentage of a fund's price movements that can be explained by movements in a given benchmark index, ranging from 0 to 1 (or 0% to 100%). An R-squared of 0.20 means only 20% of the fund's movement correlates with the S&P 500 — the fund behaves very differently from that benchmark, likely due to different holdings, sector weightings, or asset classes. Because beta is only meaningful when R-squared is reasonably high (commonly cited as above 0.70–0.80), a low R-squared like 0.20 means the fund's beta relative to the S&P 500 cannot be relied upon as an accurate risk measure. R-squared says nothing about outperformance (that's alpha) and is not itself alpha.

• A. A low R-squared of 0.20 means the S&P 500 explains little of the fund's movement, so beta is unreliable here and does not support meaningful comparisons with peer funds.
• B. R-squared is not alpha; it says nothing about excess risk-adjusted return, so this conflates two different statistics.
• C. R-squared measures the strength of the statistical relationship between two return series, not relative performance or outperformance.
• D. R-squared of 0.20 means only ~20% of the fund's return variability is explained by the benchmark, so beta versus the S&P 500 isn't a meaningful risk measure for this fund — this is the correct interpretation.

Correct answer: B. Beta measures a security's volatility relative to the overall market, while standard deviation measures the total dispersion of returns around the mean.

Beta measures systematic (market) risk — how a security's returns move relative to the overall market — and is used mainly for diversified portfolios. Standard deviation measures total risk (systematic plus unsystematic), reflecting the full dispersion of a security's returns around its average. Choice B correctly separates these two roles.

• A. Reversed: beta captures systematic risk relative to the market, not total risk; standard deviation captures total risk, not just systematic risk.
• B. Correct. Beta = relative market sensitivity; standard deviation = total return dispersion.
• C. Standard deviation reflects total risk (systematic + unsystematic), not just diversifiable risk, and beta does not restate diversifiable risk — it captures non-diversifiable (systematic) risk.
• D. Beta is a systematic-risk measure and standard deviation captures total risk; neither isolates unsystematic risk, and systematic risk cannot be diversified away.
