What the Sharpe ratio actually measures

The Sharpe ratio is one number that answers a simple question: how much return did this fund generate for each unit of risk it took? The formula is straightforward. Take the funds return, subtract the risk-free rate (typically the yield on short-term Treasury bills), and divide by the fund’s volatility (the standard deviation of its returns).

Think of it like fuel efficiency. Two cars might both travel 300 miles, but if one does it on 10 gallons and the other on 30 gallons, the first car is more efficient. The Sharpe ratio is the same concept applied to investment returns. Two funds might both return 40%, but if one had 20% annualized volatility and the other had 60%, the first fund was three times more efficient at converting risk into return.

For crypto hedge funds, this matters enormously because volatility is the defining characteristic of the asset class. Bitcoin’s annualized volatility has ranged from 50% to 200% over the last decade. A fund that returns 40% with 40% volatility (Sharpe of roughly 1.0) is doing something fundamentally different from a fund that returns 40% with 80% volatility (Sharpe of roughly 0.5). The first manager is adding value through risk management. The second is just riding the market with no risk reduction.

What counts as a “good” Sharpe ratio in crypto

Context matters. A Sharpe ratio of 1.0 means something very different in crypto than in traditional hedge funds, because the underlying volatility is so much higher. Here is a rough guide:

For comparison: the S&P 500’s long-term Sharpe ratio is approximately 0.4 to 0.5. Traditional hedge funds average around 0.6 to 0.8. The fact that crypto hedge funds averaged 1.6 in 2025 reflects both the strong absolute returns in crypto and the improving risk management practices across the industry. It does not necessarily mean crypto fund managers are more skilled than equity managers. It partly reflects that crypto offers higher returns per unit of risk when markets are trending up. In bear markets, crypto Sharpe ratios collapse.

Sharpe ratios by strategy

This is where the data gets interesting. Different crypto fund strategies produce very different Sharpe profiles, and the ranking by Sharpe is not the same as the ranking by raw returns.

Quant funds lead at 2.51. This is a standout number. Algorithmic and quantitative crypto funds have the highest average Sharpe ratio of any strategy category, and it is not close. The reason: quant strategies are designed to manage volatility. They use systematic risk controls, position sizing, and hedging that dampen the wild swings of crypto while capturing enough of the upside to generate strong returns. The best quant shops in crypto are producing risk-adjusted returns that rival the best systematic traders in traditional markets.

Market-neutral strategies at 2.10. Arbitrage and market-neutral funds generate their returns from structural inefficiencies (price differences across exchanges, basis trades, funding rate arbitrage) rather than from directional crypto exposure. Their returns are lower in absolute terms, but the volatility is dramatically lower too. The result is a strong Sharpe ratio that looks excellent on an allocator’s risk budget.

Long-only at 0.80. Long-only funds have the lowest Sharpe ratios because they take the most directional risk. They go up when the market goes up and down when the market goes down. There is minimal risk management. The Sharpe ratio reflects that: decent returns, but at the cost of very high volatility. For an allocator who can handle the drawdowns and has a long time horizon, long-only can work. For most institutional portfolios, it is too volatile.

The Sortino ratio: a better metric for crypto?

The Sharpe ratio has a well-known flaw. It treats upside volatility the same as downside volatility. If a fund has a month where it goes up 30%, that adds to volatility and actually lowers the Sharpe ratio. But as an investor, you do not mind upside volatility. You mind downside volatility. The Sharpe ratio penalizes you for making money aggressively, which is perverse.

The Sortino ratio fixes this. It uses the same formula as the Sharpe ratio but replaces total volatility with downside deviation: only the volatility of negative returns counts. The result is a measure that focuses exclusively on the risk you actually care about.

In crypto, where returns are highly asymmetric (big up months and big down months), the Sortino ratio often tells a different story than the Sharpe ratio. The average crypto hedge fund Sortino ratio in 2025 was approximately 3.2, well above the average Sharpe of 1.6. The gap between the two numbers indicates that a meaningful portion of crypto fund volatility comes from the upside, not the downside. Funds with strong positive skew (occasional very large gains) look much better on a Sortino basis than on a Sharpe basis.

Our recommendation for allocators: look at both. The Sharpe ratio is the industry standard and is useful for comparing across asset classes. The Sortino ratio is more relevant for understanding how a crypto fund actually behaves from a downside risk perspective. If a fund has a mediocre Sharpe but a strong Sortino, it means the volatility is skewed to the upside. That is usually a good thing.

How crypto Sharpe ratios have changed over time

Crypto fund Sharpe ratios are not stable over time. They move with market conditions, and the swings can be dramatic.

In 2020-2021 (the last big bull run), crypto hedge fund Sharpe ratios were extremely high. Everything was going up. Volatility was high, but returns were even higher. Average Sharpe ratios across the industry exceeded 2.0 in some quarters. This made every fund manager look brilliant.

In 2022 (the bear market), Sharpe ratios collapsed. Many funds had negative Sharpe ratios, meaning they lost money after adjusting for the risk-free rate. The Luna crash, the Three Arrows Capital failure, and the FTX collapse destroyed returns for funds with any directional exposure. Only market-neutral strategies maintained positive Sharpe ratios through the worst of it.

In 2023-2024, Sharpe ratios recovered as the market stabilized and began trending up again. The industry average climbed back above 1.0 and continued improving into 2025.

The lesson: do not evaluate a fund’s Sharpe ratio based on a single calendar year. A fund with a 3.0 Sharpe in 2025 and a -1.0 Sharpe in 2022 has a very different profile from a fund with a consistent 1.2 Sharpe across both years. The second fund is more predictable and more useful in a portfolio. Look at multi-year Sharpe ratios (3-year and since-inception) to get a more stable picture. Our Performance Database calculates Sharpe ratios over multiple time windows for exactly this reason.

Bitcoin’s Sharpe ratio vs. crypto funds

Bitcoin’s own 12-month Sharpe ratio reached approximately 2.4 in 2025, which is remarkable. This happened because Bitcoin’s volatility has been compressing over time (from 200%+ annualized a decade ago to roughly 50% now) while returns remained strong. Bitcoin in 2025 was less volatile than it used to be and still went up a lot. That combination produces a high Sharpe ratio.

This creates an awkward benchmark problem for crypto fund managers. If passive Bitcoin exposure delivers a 2.4 Sharpe, why should an allocator pay 2-and-20 to a hedge fund with a 1.6 Sharpe? The honest answer: in 2025, many crypto hedge funds did not clear the Bitcoin Sharpe bar. The ones that did were mostly quant strategies and market-neutral strategies that delivered their returns with significantly less drawdown risk than Bitcoin.

But Bitcoin’s Sharpe ratio is unstable. In 2022, Bitcoin’s Sharpe was deeply negative. Over a full cycle, Bitcoin’s long-term Sharpe is closer to 0.9 to 1.0. A crypto hedge fund that consistently delivers a 1.5+ Sharpe through bull and bear markets is doing something that Bitcoin alone cannot. The value is in the consistency, not in beating Bitcoin in any single year. For more on this comparison, see our article on crypto hedge funds vs. Bitcoin.

What the Sharpe ratio does not tell you

It does not capture tail risk. The Sharpe ratio uses standard deviation, which assumes returns follow a normal distribution. Crypto returns do not. They have fat tails, meaning extreme events happen more often than a normal distribution predicts. A fund can have a great Sharpe ratio and still blow up in a tail event. Luna-exposed funds had strong Sharpe ratios right up until they did not.

It can be gamed. Managers who sell options (collecting premium in exchange for tail risk) can produce artificially high Sharpe ratios for extended periods. The returns look smooth and consistent until the tail event hits and they give back years of gains in a week. If a Sharpe ratio looks too good to be true, ask what the strategy actually does. If the answer involves selling volatility, the Sharpe is misleading.

It says nothing about liquidity. A fund investing in illiquid tokens can report smooth NAVs (because the tokens do not trade actively and thus do not show volatility) and produce a high Sharpe ratio. The volatility is not absent. It is just hidden. When those tokens eventually trade, the real volatility shows up. Smoothed NAVs are a known source of Sharpe inflation in both crypto and traditional hedge funds.

It changes with the measurement period. A fund’s 1-year Sharpe can look completely different from its 3-year Sharpe. Always check which time period is being cited. A manager showing you their “Sharpe ratio” without specifying the period is probably showing you the most flattering window.

How allocators should use these metrics

Use Sharpe as a filter, not a selection tool. Screen out funds with Sharpe ratios below your minimum threshold (for most institutional allocators, that is somewhere around 0.8 to 1.0 over a 3+ year period). Then evaluate the survivors on qualitative factors: team, process, operational quality, and strategy fit. The Sharpe ratio narrows the field. It does not make the decision for you.

Compare within strategies, not across them. A market-neutral fund with a 2.0 Sharpe and a long/short fund with a 1.3 Sharpe are both doing their jobs well. Comparing them on Sharpe alone is like comparing the fuel efficiency of a motorcycle and a truck. They serve different purposes. Evaluate each fund against its strategy peers.

Look at Sharpe alongside drawdown. Two funds can have identical Sharpe ratios but very different maximum drawdowns. One might have smooth 2% monthly gains. The other might have 30% up months followed by 20% down months. Both paths produce the same Sharpe, but the second one is much harder to sit through. Our article on crypto fund drawdowns covers this in detail.

Verify the calculation. When a fund manager tells you their Sharpe ratio, ask: over what period? Using what risk-free rate? Annualized or not? Gross or net of fees? These details change the number meaningfully. Our Performance Database uses a standardized methodology (monthly returns, annualized, net of fees, T-bill risk-free rate) so that every fund’s Sharpe is calculated the same way. That consistency is what makes comparison possible.
