What is the Sharpe Ratio?
Two funds can post the same return while one took a much bumpier ride to get there. Sharpe Ratio answers “was the extra risk worth it?” by dividing excess return by volatility.
Sharpe = (Rp − Rf) / σp
Higher is better - more return earned per unit of volatility taken.

CHART
3Y Sharpe Ratio - 6 real funds
Same 3-year window, computed against each fund's own benchmark.
Funds compared: Parag Parikh Flexi Cap · DSP Value · ICICI Prudential Value · SBI Focused · Parag Parikh ELSS Tax Saver · SBI Multicap
Reading the spread
Across these 6 funds, 3-year Sharpe Ratio runs from 0.39 (Parag Parikh ELSS Tax Saver) to 1.02 (DSP Value), a gap of 0.64. The middle value is 0.71, with 3 of 6 above it. The highest reading is 2.7 times the lowest, so the choice of fund changes this number a lot. Taking higher as better, DSP Value leads and Parag Parikh ELSS Tax Saver trails on this measure alone.
How to use it in practice
Use Sharpe to compare funds in the same category over the same window. Put two flexi cap funds side by side and the one with the higher ratio earned more return for each unit of volatility it carried. It is most useful when two funds have similar returns, because the ratio then tells you which one got there with fewer sleepless nights. Pair it with standard deviation to see the risk behind the ratio and with Sortino when you care about downside only.
Common mistakes
The most common mistake is comparing Sharpe across categories: a debt fund and a small cap fund have very different volatility, so their ratios are not on the same footing. A second is reading a high ratio as safety. Sharpe measures return per unit of volatility, not the chance of loss, and a fund can score well and still fall hard in a bad year. Finally, a ratio from a short or unusually calm window flatters a fund, so look at the same measure over more than one period.
Frequently asked questions
What is a good Sharpe Ratio?
There is no single threshold, because the figure depends on the category, the window and the risk-free rate used. A useful approach is to compare a fund with the median of its own category over the same period: a Sharpe above the category median means better return per unit of risk than the typical peer. A ratio above 1 is often described as good, but a calm market can lift every fund’s ratio.
Can the Sharpe Ratio be negative?
Yes. If a fund’s return is below the risk-free rate, the excess return is negative and so is the ratio. It means investors were not paid for the volatility they took on, compared with a risk-free deposit.
Which is better, Sharpe or Sortino?
Neither is better in general. Sharpe counts all volatility, so it penalises sharp rises as well as falls. Sortino counts only downside volatility, which matches how most investors feel about risk. When the two rank funds differently, it usually means one fund’s volatility came mostly from rising prices.
WHAT THIS MEANS FOR YOU A fund with a lower headline return but a higher Sharpe Ratio delivered a smoother ride per unit of return - don’t compare two funds on CAGR alone without checking this.
