DEFINITION of 'Sterling Ratio'
A ratio used mainly in the context of hedge funds. This riskreward measure determines which hedge funds have the highest returns while enduring the least amount of volatility. The formula is as follows:
This formula uses the average for risk (drawdown) and return over the past three years. Drawdown is calculated at the maximum potential loss in the given year.
BREAKING DOWN 'Sterling Ratio'
Just like the Calmar ratio, a higher Sterling ratio is generally better because it means that the investment(s) are receiving a higher return relative to risk.
The Sterling ratio is similar to the Sharpe ratio and the Sortino ratio, as it also produces a riskadjusted return measurement. The Sterling ratio, along with the Sortino ratio, is primarily used by hedge funds as a way of advertising superior risk management.
