What is Sharpe Ratio? 

A principle of investing is that there is a connected relationship between generating returns (profit) and taking risk. Sharpe Ratio is a formula that measures whether your returns are large enough to compensate for the amount of risk you are taking.

Sharpe Ratio determines those who are making money due to a few lucky decisions, or if there is a consistent pattern for generating returns (profit).

Formula:

Sharpe Ratio = (Rx – Rf) / StdDev Rx

Where:

  • Rx = Expected portfolio return
  • Rf = Risk free rate of return
  • StdDev Rx = Standard deviation of portfolio return  (volatility)

Why are we using Sharpe Ratio?

When you’re only thinking about returns, it can be easy to get lucky and score big wins. But when it comes to maximizing your Sharpe ratio, luck doesn't cut it. Sharpe Ratio helps us determine those who are making money due to a few lucky decisions, or if there is a consistent pattern for generating returns (profit).
