How It Works

Compute the deflated Sharpe ratio by adjusting for selection bias from testing multiple strategies. DSR = PSR(SR* = E[max Sharpe of N trials]), accounting for skewness, kurtosis, and data snooping

Each component has a specific meaning:

  • Testing multiple strategies — The testing multiple strategies recorded for the scenario being assessed.

Note: Interpret the deflated sharpe result against the thresholds and context described above.

How to Use

Enter the testing multiple strategies for the scenario you are assessing. Compute the deflated Sharpe ratio by adjusting for selection bias from testing multiple strategies. DSR = PSR(SR* = E[max Sharpe of N trials]), accounting for skewness, kurtosis, and data snooping. Use the deflated sharpe result to inform your calculation.
