The risk-free rate was initially used in the formula to denote an investor's hypothetical minimal borrowing costs. standarddeviationoftheportfoliosexcessreturn Another variation of the Sharpe is the Treynor ratio, which divides excess return over a risk-free rate or benchmark by the beta of a security, fund, or portfolio as a measure of its systematic risk exposure. In addition of evaluating the risk-free rate, it revolves around returns maximization and volatility reduction. . Whether it's right or wrong really has to do with your assumption of how stock returns are really distributed. Sp= Standard Deviation of the Portfolio/Investment.

Though practically impossible, the investment with a 10% annual return and zero volatility has an infinite Sharpe index. S&P 500 performance is 10%. The second calculation in the utility block is based on a piecewise linear utility function. So the "risk-free rate" applied to each month may vary over time. Named after American economist, William Sharpe, the Sharpe Ratio (or Sharpe Index or Modified Sharpe Ratio) is commonly used to gauge the performance of an investment by adjusting for its risk. Solution: Excess Return is calculated as: Similarly, calculated as below. @AndreTerra - The "risk free" rate should be as close to "risk free" as possible. For example, the numerator of a 10-year Sharpe ratio might be the average of 120 monthly return differentials for a fund versus an industry benchmark. For 2 and 3 year normalization, you'd want to substitute the numerator "1 year" with "2 years" and "3 years". It demonstrates the excess return the investor gains after taking excess risk.

The result can be raised by adding assets to a portfolio to improve its diversification. Ratio If you assume that your capital $C$ can be described as a Geometric Brownian Motion (GBM) with annualized drift $\mu$ and annualized standard deviation $\sigma$, then a correct way to calculate Sharpe Ratio ($\frac{\mu}{\sigma}$, disregarding risk free rate) would be as follows: Find mean ($\bar{\mu}$) and standard deviation ($\bar{\sigma}$) of the daily log returns, $$\frac{\mu}{\sigma} = \left(\frac{\bar{\mu}}{\bar{\sigma}} + 0.5 \bar{\sigma}\right) \times \sqrt{DaysPerYear}$$.

The higher the ratio, the greater the investment return relative to the amount of risk taken, and thus, the better the investment.

The excess rate of return of the portfolio is calculated by deducting the risk free rate of return from the actual rate of return of the portfolio.
