Sharpe Ratio

The Sharpe ratio measures return earned per unit of total risk, above the risk-free rate. A higher Sharpe means better risk-adjusted returns; it lets you compare funds that took different amounts of volatility.

sharpe = (mean(r_m - rf_m) / stddev(r_m)) * sqrt(12), with rf_m = 0.07/12

What the Sharpe ratio tells you

Raw returns can flatter a fund that simply took big risks. The Sharpe ratio fixes this by dividing excess return (return above a safe rate) by total volatility. It rewards funds that earned their returns smoothly.

How to read it

How FindMF computes it

We resample each fund's NAV (from AMFI data) to month-end and take monthly returns over completed months only. We subtract a monthly risk-free rate (7% annualised G-Sec, or 0.07/12 per month), divide the mean excess return by the standard deviation of monthly returns, then annualise by multiplying by sqrt(12). We require at least 12 months of history; below that, Sharpe is suppressed rather than computed on thin data. We earn no commission — see methodology.
