Sortino Ratio Formula

Excess Return = Return - Risk-free Rate

Downside Deviation = sqrt( sum( min(0, r - Rf)² ) / N )

Sortino (periodic) = Mean Excess Return / Downside Deviation

Sortino (annual) = Sortino (periodic) × √(periods per year)

Where N = total number of periods, only negative deviations count toward downside
