For example, assume Mutual Fund X has an annualized return of 12% and a downside deviation of 10%. Mutual Fund Z has an annualized return of 10% and a downside deviation of 7%. The risk-free rate is 2.5%. The Sortino ratios for both funds would be calculated as:
Mutual Fund X Sortino = (12% - 2.5%) / 10% = 0.95
Mutual Fund Z Sortino = (10% - 2.5%) / 7% = 1.07
