Sortino Ratio Analysis

Calculation

The Sortino Ratio, a modification of the Sharpe Ratio, focuses specifically on downside risk, measuring risk-adjusted returns based on negative volatility. Within cryptocurrency and derivatives markets, this distinction is crucial given the asymmetric return distributions often observed, where substantial negative price movements can disproportionately impact portfolio performance. Its computation involves subtracting the risk-free rate from the portfolio return, then dividing this result by the downside deviation—the standard deviation of negative portfolio returns. This metric provides a more refined assessment of risk-adjusted performance for strategies exposed to significant tail risk, common in volatile asset classes.
