Which of the following are characteristics of the Sharpe ratio?

• A. I. It adjusts the return for variability by using standard deviation as the measure of risk.
• B. II. It assumes that the portfolio being evaluated is well diversified.
• C. III. Both alpha and beta appear in the ratio formula.
• D. IV. It indicates by how much the realized return differs from the return required by the capital asset pricing model.

Answer: (C)

The Sharpe ratio is a key measure of risk-adjusted return that helps investors understand how much excess return they are receiving for the additional volatility they endure for holding a riskier asset. The correct characteristics of the Sharpe ratio include using standard deviation as a measure of risk, which adjusts the average return of the investment by the volatility experienced over a period of time, allowing for a clearer comparison between various investments. In examining the distinct elements of the Sharpe ratio, it is important to note that it does not incorporate both alpha and beta within its formula. The Sharpe ratio is primarily focused on excess return relative to standard deviation, and while these terms relate to investment performance—alpha being a measure of an investment's performance on a risk-adjusted basis and beta measuring an asset's volatility relative to the market—neither is part of the Sharpe ratio's calculation. In essence, the correct answer relates to characteristics that are foundational to understanding the Sharpe ratio's role in evaluating investment performance, while statements regarding alpha and beta do not align with its definition.
