Discover how to evaluate investment performance using metrics like standard deviation, beta, alpha, and the Sharpe ratio for risk-adjusted returns.
Understanding investment performance measurement is critical for professionals in the financial industry. Grasping the concepts of risk and return helps investment company and variable contracts products representatives make informed decisions. This article will delve into core metrics like standard deviation, beta, alpha, and the Sharpe ratio.
Definition: Standard deviation is a statistical measure of the volatility or dispersion of investment returns. A high standard deviation indicates high volatility, which translates to higher risk.
Explanation: It gives investors insight into the stability of an investment’s returns over a specific period. Typically, a lower standard deviation suggests a more stable investment.
Example: Consider two mutual funds. Fund A has a standard deviation of 5%, while Fund B has a standard deviation of 15%. Fund A is relatively less risky compared to Fund B.
Consider the below Mermaid diagram illustrating the concept of standard deviation in a normal distribution of expected returns:

Definition: Beta measures an investment’s sensitivity to market movements. A beta higher than 1 indicates higher volatility than the market.
Explanation: Beta helps investors understand how an investment moves in relation to broader market indices.
Example: A stock with a beta of 1.2 is 20% more volatile than the market. If the market increases by 10%, theoretically, the stock should increase by 12%.
Definition: Alpha represents the excess return of an investment relative to the return of a benchmark index.
Explanation: Synthesizing various factors, alpha reflects the manager’s skill in generating returns above what the market has predicted.
Example: If a mutual fund earned 7% returns while the benchmark index was at 5%, and given the beta, alpha would be the additional 2% return attributed to the manager’s performance.
Definition: The Sharpe Ratio is a measure for calculating risk-adjusted return, assessing how much excess return you receive for the extra volatility endured holding a riskier asset.
Explanation: A higher Sharpe ratio is desirable; it indicates that returns were not only high but also efficient concerning risk.
Example Formula: \( \text{Sharpe Ratio} = \frac{R_p - R_f}{\sigma_p} \)
