Sharpe Ratio Limitations

The Sharpe ratio is a common metric used to measure the risk-adjusted return of an investment, calculated by dividing the excess return by the standard deviation of returns. While widely used, it has significant limitations, especially in the context of cryptocurrency.

It assumes that returns follow a normal distribution, which is rarely the case in crypto markets, where extreme moves and fat tails are common. Furthermore, it treats upside volatility as a negative factor, penalizing strategies that have large positive outliers.

The Sharpe ratio also does not account for liquidity risk or the potential for systemic failure in a protocol. Because of these flaws, analysts often supplement it with other metrics like the Sortino ratio or Omega ratio to get a more accurate picture of risk-adjusted performance.

Relying solely on the Sharpe ratio can lead to a false sense of security.
