What is the step-by-step calculation?

Let's go through the calculation of the annualized return step-by-step for a symphony backtest. Here's how we do it:

  • Compute the cumulative percent return of the symphony for the time between the first and last date in the backtest

  • Add one to that value

  • Raise that result to the (252/N) power, where N is the number of trading days in the backtest

  • Subtract 1 from that result
