# Sharpe Ratio: Formula, Calculation, Importance And Limitations

A beta of less than 1.0 indicates that the fund NAV will be less volatile than the benchmark index. By computing with above formula, we will get alpha as 0.44 for this fund. The Sharpe Ratio assumes that the returns are normally distributed and that the risk-free rate is constant. Therefore, even if the positive deviations are higher, the SD of the fund could be higher, which may portray the fund to be risky while actually, that may not be the case. The following table shows the Sharpe ratio of different Mutual Fund categories and contains the funds with the highest Sharpe ratio in various categories. Volatility is a measure of the value fluctuations of an asset or portfolio.

When investors must select from a broad universe of possible investments securities, it helps to explicitly consider risk and return as factors of overall investment success.

Because the denominator can by no means be unfavorable, Sharpe ratio is negative when the numerator is negative, which is when the return on the funding is smaller than the risk-free fee.

After the addition, the portfolio return turns into 25 per cent and normal deviation stays at 10 per cent. If the danger-free rate is taken as 5 per cent, the brand new Sharpe ratio might be 2 [(25%-5%)/10%]. A zero-beta portfolio is a portfolio constructed to have zero systematic danger, or in other phrases, a beta of zero. A zero-beta portfolio would have the identical anticipated return as the chance-free fee. Mutual Fund investments are subject to market risks, read all scheme related documents carefully before investing. Thus, while Investing, investors should choose a fund that shows a higher Sharpe ratio.

The Sharpe ratio may be recalculated on the finish of the 12 months to examine the actual return rather than the anticipated return. Roy’s ratio is also related to the Sortino ratio, which also uses MAR within the numerator, but uses a different standard deviation (semi/downside deviation) within the denominator. Portfolio diversification with belongings having low to adverse correlation tends to cut back the overall portfolio risk and consequently will increase the Sharpe ratio. Standard deviation is used to measure variation from arithmetic mean generally. But in finance, standard deviation refers to a statistical measure or tool that represents the volatility or risk in a market instrument such as stocks, mutual funds etc. Portfolio return can be daily, weekly or monthly but it is important to not take these figures during unrealistic situations as the result would not depict an accurate figure.

## How to calculate the Sharpe ratio of a portfolio?

It enables the investor to understand incentives that a portfolio offers at a given risk level compared to that of the benchmark portfolio and risk-free rate.

The Modigliani-Modigliani measure or the M2 measure evaluates the investment’s risk-adjusted return. It indicates the risk-adjusted return of an investment in comparison with a benchmark. But, as the SD of Fund B is higher than Fund A, the Sharpe ratio of B is lower. Even Fund C is delivering 10 percentage points higher than Fund A. But due to a higher standard deviation, the Sharpe ratio is the same for both funds. If thought of in isolation, it doesn’t present a lot information about the fund’s efficiency.

It is usually measured as the return offered by Government securities. These returns are the benchmark returns that your money can get without taking on any risks. The Sharpe ratio measures how the asset is performing against the benchmark. The Sharpe ratio assumes that returns are normally distributed, but in actual market conditions, this is not the case. The returns are unevenly distributed which might depict an inaccurate result at times.

Treynor ratio is a version of the sharpe ratio that is calculated using a portfolio’s beta . If the value is one, then the fund’s response is equivalent to the markets or the shift in the price of the mutual fund is the same as the benchmark movements.

If two funds offer similar returns, the one with higher standard deviation will have a lower Sharpe ratio. In order to compensate for the higher standard deviation, the fund needs to generate a higher return to maintain a higher Sharpe ratio.

See more detailed explanation of negative Sharpe ratio interpretation. He or she assumes that the chance-free fee will remain the same over the coming 12 months. Using the same formula, with the estimated future numbers, the investor finds the portfolio has the expected Sharpe ratio of 107%, or (11% – three.5%) divided by 7%.

• Returns can be for any time period, but it is always better to take a long-term period.
• Let’s add another asset class to the portfolio, namely a hedge fund, and tweak the portfolio allocation to 50 per cent in equity, 40 per cent in bonds and 10 per cent in the hedge fund.
• The ratio is the common return earned in extra of the chance-free fee per unit of volatility or complete threat.
• A fund with a larger standard deviation should achieve higher returns to maintain a higher Sharpe ratio.

A negative Sharpe ratio means the portfolio has beneath-performed its benchmark. All other things being equal, an investor desires to extend a constructive Sharpe ratio, by growing returns and reducing volatility. It is a historical measure used to evaluate the investment portfolio’s returns over a period of time.
