What is the Sortino Ratio?
The Sortino Ratio is a variation of the Sharpe Ratio that only penalizes downside (harmful) volatility, rather than total volatility, giving a more targeted view of risk-adjusted return for risk-averse investors.
The formula
Sortino Ratio = (Portfolio Return − Target Return) / Downside Deviation. Because it ignores upside volatility, the Sortino Ratio is often higher than the Sharpe Ratio for the same investment, and is considered a better fit when returns are not symmetrically distributed.
