What Is a Good Sharpe Ratio for Trading?

The Sharpe ratio measures how much return you earned for each unit of volatility you took on. As a rough guide, above 1 is considered decent, above 2 is strong, and above 3 is exceptional. Those benchmarks come from the fund world, though, and that is the catch: the Sharpe ratio was built to compare portfolios, not to coach an individual trader. For most people reading this, it is the wrong tool, and a simpler set of numbers will tell you more about whether you have an edge.

What the Sharpe ratio measures

The idea is reasonable. Two strategies can earn the same return, but if one did it with a smooth, steady climb and the other with wild swings, the smooth one is better, because you took less risk to get the same result. The Sharpe ratio puts a number on that by dividing your return, above the risk-free rate, by the volatility of your returns. Higher means more return per unit of bumpiness.

That is genuinely useful information. A high return that came from one lucky, enormous swing is worth less than the same return earned steadily, and the Sharpe ratio is one of the few common numbers that captures the difference. The problem is not the concept. It is what the concept assumes about who is using it.

Why it is usually the wrong tool for a trader

The Sharpe ratio was designed for portfolios that stay invested and can be measured as a continuous stream of returns. An individual trader who moves in and out of positions, holds cash between setups, and takes a handful of trades a week does not produce the kind of clean return series the ratio assumes. Force your trading into a Sharpe number and you get a figure that is sensitive to your timeframe, your position sizing, and how much you happened to sit in cash, none of which is really what you wanted to know.

There is a deeper objection too. The Sharpe ratio treats all volatility as bad, including upside. A month where several trades ran to big winners increases your volatility and can lower your Sharpe ratio, which is backwards for a trader who wants exactly those outlier winners. Punishing your best months is not the feedback you need.

What a good number looks like, if you must

If you or a platform is computing a Sharpe ratio on your trading and you want a rough read: below 1 is weak, around 1 to 2 is solid, and above 2 is very good, over a meaningful sample. But hold those numbers loosely. A Sharpe ratio built from thirty trades is as unreliable as any other metric built from thirty trades, and the smaller and lumpier your trade history, the less the number means. The post on how many trades you need applies here as much as anywhere.

The benchmark is also easy to game in ways that do not help you. Trade tiny, take profits fast, and avoid any position with real upside, and your Sharpe ratio can look great while your actual profit is trivial. A pretty ratio on a strategy that barely makes money is not a win.

Track these instead

For an individual trader, a few plainer numbers do the same job with far less distortion.

Expectancy tells you what you make per trade on average, which is the thing you actually care about. The expectancy formula is the honest core metric, and unlike Sharpe it does not penalize you for big winners.

Profit factor gives you the ratio of what you make to what you lose, a clean health check covered in the post on what a good profit factor is.

Max drawdown covers the risk side that Sharpe was reaching for, but in a way you can feel: the worst drop you actually had to sit through. That is a more useful measure of the ride than a volatility figure that also dings your best months.

The takeaway

A good Sharpe ratio is above 1, and above 2 is strong, but the honest answer for most traders is that it is not the number to chase. It was built for portfolios, it treats your best winners as risk, and it distorts easily on the lumpy return stream a trader produces. Track expectancy, profit factor, and max drawdown instead. They tell you what you make, the ratio behind it, and the worst you had to endure, which is everything the Sharpe ratio was reaching for and easier to act on. The analytics compute those three from your trades, so you can skip the fund math and read the numbers that actually fit how you trade.
