Backtesting Sortino Ratio

Calculation

Backtesting Sortino Ratio quantifies risk-adjusted returns of a strategy during a historical period, specifically focusing on downside risk. It differentiates itself from the Sharpe Ratio by only considering negative deviations from the mean, providing a more pertinent measure for strategies where unfavorable volatility is a primary concern, such as those employed in cryptocurrency derivatives. This metric is crucial for evaluating the efficacy of trading algorithms and portfolio construction techniques across diverse financial instruments.
