Sharpe Ratio

The Sharpe Ratio is a measure used to understand the performance of an investment by adjusting for its risk. It is calculated by subtracting the risk-free rate from the portfolio return and dividing the result by the standard deviation of the portfolio returns.

A higher Sharpe Ratio indicates that an investment is providing better returns per unit of risk taken. In cryptocurrency markets, where volatility is often extreme, this ratio helps investors distinguish between high returns generated by skill and those resulting from excessive risk-taking.

It is particularly useful when comparing different crypto-asset strategies or protocols. By normalizing for volatility, it allows for a more accurate comparison of diverse assets.

The ratio assumes that risk is represented by volatility, which may not capture all risks in crypto, such as smart contract failure. Despite this limitation, it remains a cornerstone of quantitative finance.

It provides a standardized way to evaluate if the added volatility of a strategy is justified.
