What is Sharpe ratio in hedge fund strategy?
The Sharpe ratio is a metric used in finance to evaluate the risk-adjusted performance of an investment. It's calculated as the ratio of the difference between the investment's return and the risk-free rate to the standard deviation of its returns.
The Sharpe ratio indicates the amount of additional return obtained for each level of risk taken. A Sharpe ratio greater than 1 is good, while ratios below 1 can be judged based on the asset class or investment strategy used.
A Sharpe ratio less than 1 is considered bad. From 1 to 1.99 is considered adequate/good, from 2 to 2.99 is considered very good, and greater than 3 is considered excellent. The higher a fund's Sharpe ratio, the better its returns have been relative to the amount of investment risk taken.
What is Sharpe Ratio? The Sharpe Ratio is the difference between the risk-free return and the return of an investment divided by the investment's standard deviation. In simple words, the Sharpe Ratio adjusts the performance for the excess risk taken by an investor.
This tells us that with a Sharpe ratio of 2, Portfolio B provides a superior return on a risk-adjusted basis. Generally speaking, a Sharpe ratio between 1 and 2 is considered good. A ratio between 2 and 3 is very good, and any result higher than 3 is excellent.
It's better to have a higher Sharpe ratio. In general, less than 1 is considered not ideal, 1 to 1.99 is adequate to good, and 2 or greater is very good or excellent, according to the Corporate Finance Institute.
A Sharpe ratio of 0.7 would be considered average at best, as a ratio of 1 and above is considered good.
Typically, the higher the Sharpe ratio, the more attractive the return and the better the investment. However, if the calculation results in a negative Sharpe ratio, it means one of two things: either the risk-free rate is greater than the portfolio's return, or the portfolio should anticipate a negative return.
The current S&P 500 Portfolio Sharpe ratio is 2.52. A Sharpe ratio higher than 2.0 is considered very good.
Two Other Factors Boosted Buffett's Performance
The AQR researchers found that Berkshire Hathaway's Sharpe Ratio (a measure of returns after adjusting for risk) is 0.79 from 1976-2017. That's about twice that of the broad market, but it's not spectacular.
What does a Sharpe ratio of 0.2 mean?
A Sharpe Ratio of 0.2 means volatility of the returns is 5x the average return. Some investors may not want investments that are up 10% one month and down 15% the next month, etc., even if the investment offers a higher overall average return.
The Sharpe ratio measures a portfolio's risk-adjusted returns. In other words: for every unit of risk I am taking, I am getting x in returns for that risk. A Sharpe ratio of 5 means that the specific risk you take on in your portfolio yields 5 units of return, in excess of the risk-free rate.
The Sharpe ratio is calculated by subtracted the risk-free rate from the holdings' rate of return, frequently utilizing U.S. Treasury bond returns as a proxy for the risk-free return rate. Subsequently, the result is divided by the standard deviation of the portfolio's excess return.
The Sharpe ratio indicates how well an equity investment is performing compared to a risk-free investment, taking into consideration the additional risk level involved with holding the equity investment. The Sortino ratio is a variation of the Sharpe ratio that only factors in downside risk.
Beta is a statistical tool, which gives you an idea of how a fund will move in relation to the market. In other words, it is a statistical measure that shows how sensitive a fund is to market moves. Sharpe Ratio: The Sharpe ratio is a single number which represents both the risk, and return inherent in a fund.
The Sharpe ratio is adequate for evaluating investment funds when the returns of those funds are normally distributed and the investor intends to place all his risky assets into just one investment fund. Hedge fund returns differ significantly from a normal distribution.
What rate of return do most hedge funds give initial investors? Most hedge and private equity funds target a net IRR of 15% for their investors (after fees). This provides their investors with a meaningful premium over historical average stock market returns of 8%.
| Rank | Firm Name | ADV Filing Date |

From the diagram it is evident that the market portfolio has the greatest Sharpe Ratio since the capital market line (efficient frontier with risk-free asset) is steeper than all other combination lines.
The problem with the Sharpe ratio is that it is accentuated by investments that don't have a normal distribution of returns. The best example of this is hedge funds. Many of them use dynamic trading strategies and options that give way to skewness and kurtosis in their distribution of returns.
Does Sharpe ratio account for leverage?
Since the risk free rate is a minor factor, Sharpe ratio can be approximately expressed as: nE(X) / STDEV(X). Leveraging just multiplies each value of the random variable X by a constant, which can be pulled out and cancelled from the numerator and denominator. Thus Sharpe ratio is independent of leverage.
A negative Sharpe ratio means the portfolio has underperformed its benchmark. All other things being equal, an investor typically prefers a higher positive Sharpe ratio as it has either higher returns or lower volatility.
However, a Sharpe ratio greater than zero is typically considered good. A zero Sharpe ratio means that your returns are matching the "risk-free" version of your investment, typically a Treasury security. While that's not necessarily bad, you also don't want to be taking on risk just to match that benchmark.
The Sharpe ratio compares an investment's excess return over a benchmark to the standard deviation of returns. The higher the Sharpe ratio, the better the investment's historical risk-adjusted performance.
“US mortgage-backed securities have the highest Sharpe ratios of all US asset classes, stock or bond. Bonds in general have a higher Sharpe ratio than stocks going back ten years.
