B) The Sharpe ratio is used to measure risk-adjusted performance of either a portfolio or an individual security. The Sharpe ratio uses standard deviation as the denominator in its formula: the higher the Sharpe ratio, the better the portfolio or security has performed on a risk-adjusted basis.

Most finance people understand how to calculate the Sharpe ratio and what it represents. The Sharpe ratio describes how much excess return you receive for the extra volatility you endure for holding a riskier asset. Remember, you need compensation for the additional risk you take for not holding a risk-free asset. We will give you a better understa...
Return
The measured returns can be of any frequency (e.g., daily, weekly, monthly, or annually) if they are normally distributed. Herein lies the underlying weakness of the Sharpe ratio: not all asset returns are normally distributed. Kurtosis—fatter tails and higher peaks—or skewness can be problematic for the Sharpe ratio as standard deviationis not as effective when these problems exist. Sometimes, it can be dangerous to use this formula when returns are not normally distributed.
Risk-Free Rate of Return
The risk-free rate of return is used to see if you are properly compensated for the additional risk assumed with the asset. Traditionally, the risk-free rate of return is the shortest-dated government T-bill(i.e. U.S. T-Bill). While this type of security has the least volatility, some argue that the risk-free security should match the duration of the comparable investment. For example, equities are the longest duration asset available. Should they not be compared with the longest duration ris...
Standard Deviation
Now that we have calculated the excess return by subtracting the risk-free rate of return from the return of the risky asset, we need to divide it by the standard deviationof the measured risky asset. As mentioned above, the higher the number, the better the investment looks from a risk/return perspective. How the returns are distributed is the Achilles heel of the Sharpe ratio. Bell curvesdo not take big moves in the market into account. As Benoit Mandelbrot and Nassim Nicholas Taleb note in...
Understanding the relationship between the Sharpe ratio and risk often comes down to measuring the standard deviation, also known as the total risk. The square of standard deviation is the variance, which was widely used by Nobel Laureate Harry Markowitz, the pioneer of Modern Portfolio Theory. So why did Sharpe choose the standard deviation to adj...
The Sharpe ratio is a measure of return often used to compare the performance of investment managers by making an adjustment for risk. For example, Investment Manager A generates a return of 15%, and Investment Manager B generates a return of 12%. It appears that Manager A is a better performer. However, if Manager A took larger risks than Manager ...
Risk and reward must be evaluated together when considering investment choices; this is the focal point presented in Modern Portfolio Theory.In a common definition of risk, the standard deviation or variance takes rewards away from the investor. As such, always address the risk along with the reward when choosing investments. The Sharpe ratio can h...

Feb 20, 2024 · The steps to calculate the Sharpe ratio are as follows: Step 1 → First, the formula starts by subtracting the risk-free rate from the portfolio return to isolate the excess return. Step 2 → Next, the excess return is divided by the portfolio’s standard deviation (i.e. the proxy for portfolio risk).
