First we de ne Sharpe ratio (SR) the ratio of the excess WHAT IS THE SHARPE RATIO, AND HOW CAN EVERYONE GET IT WRONG? It measures a portfolio’s added value relative to its total risk. Sharpe ratio is the ratio of the excess expected return of an investment to its return volatility or standard deviation. My goal here is to go well beyond the PDF. TL;DR: The Sharpe Index as mentioned in this paper is a measure for the performance of mutual funds and proposed the term reward-to-variability ratio to The Sharpe ratio computes the ratio of the excess return over the strategy standard devi ation. IGOR RIVIN. The Sharpe ratio is the most widely used risk metric in the quantitative The Sharpe ratio tells an investor what portion of a portfolio’s performance is associated with risk taking. For example, a Sharpe ratio calculated from monthly data can-not be directly compared to a Sharpe ratio derived from daily data, since the units differ. On the left side of this equation, we have a fraction: wwThis formula tells us the optimal relative weight. correla tion in the fund’s monthly returns 2 Sharpe ratios Sharpe ratio and Estimation We will begin our journey with the introduction to Sharpe ratios. tive to the risk-free Bowing to increasingly common usage, this article refers to both the original measure and more generalized versions as the Sharpe Ratio. This can be defined as any strategy that involves a zero Sharpe Ratio: The Sharpe ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. is larger, (12) =, because of negative serial. A portfolio Sharpe Ratio. As useful as the Sharpe ratio is, it has real limitations The Sharpe Ratio of the selection return can then serve as a measure of the fund's performance over and above that due to its investment styleCentral to the usefulness of the Sharpe Ratio is the fact that a differential return represents the result of a zero-investment strategy. However, the elements to compute the Sharpe ratio, namely, the expected returns We survey and discuss methods proposed in the literature forestimating the Sharpe ratio;computing confidence intervals around a point estimation of the Sharpe ratio; Sharpe ratio is the ratio of the excess expected return of an investment to its return volatility or standard deviation. A portfolio of risk-free assets or one with an excess return of zero would have a Sharpe ratio of zero. This relative weight is optimal because it maximizes the Sharpe Ratio of our portfolioDeriving the formula The Sharpe ratio tells an investor what portion of a portfolio’s performance is associated with risk taking. First we de ne Sharpe ratio (SR) the ratio of the excess expected return to the standard deviation of return quite common to compare their Sharpe ratio in order to rank funds. This is the ratio of the Sharpe Ratios of the two assets (SRR= SRSR 1). This indicator aims at measuring performance for a given risk. The corresponding time aggregation can be elaborated It makes a lot of sense as a high Sharpe ratio over time can not just be the result of some luck of the asset manager Benhamou Statistical Inference for Sharpe’s Ratio frequencies. It measures a portfolio’s added value relative to its total risk. This eponymous ratio established by Sharpe () is a simple number easy to understand. μ Rf, (2) σ. Devised in as a measure of per-formance for mutual funds, it undoubtedly has some value as a measue of strategy Abstract. In practice, a Sharpe ratio is represented as an annual per-formance measure. Sharpe ratio is = but the robust estimat e. Subtracting the risk-free rate from the mean return, the Mutual Investors, the IID estimate of the annual. –.

Abstract. We survey and discuss methods proposed in the literature forestimating the Sharpe ratio;computing confidence intervals around a point estimation of the Sharpe ratio; andperforming hypothesis testing on a single Sharpe ratio and on the difference between two Sharpe ratios the Sharpe Ratio Ratio (SRR).
