The Calmar Ratio evaluates how much return an investment generates relative to its worst-case historical drop. By using Maximum Drawdown as the risk measure rather than standard deviation, it is highly sensitive to tail risk and catastrophic losses.
A high Calmar Ratio (e.g., > 1.0) means the asset recovers its full historical drawdown relatively quickly through consistent growth. A low Calmar Ratio (< 0.5) implies that its worst historical loss was exceptionally severe compared to its average return.
In StressTest.pro, the Calmar Ratio relies on the maximum drawdown historically observed in the testing period. This metric is especially valuable for conservative or timing-sensitive investors looking to protect capital from severe corrections.
