Sharpening Sharpe Ratios [PDF]
SSRN Electronic Journal, 2002 It is now well known that the Sharpe ratio and other related reward-to-risk measures may be manipulated with option-like strategies. In this paper we derive the general conditions for achieving the maximum expected Sharpe ratio. We derive static rules for achieving the maximum Sharpe ratio with two or more options, as well as a continuum of derivative ...

Adjusted Empirical Likelihood Method in the Presence of Nuisance Parameters with Application to the Sharpe Ratio [PDF]
Entropy, 2018 The Sharpe ratio is a widely used risk-adjusted performance measurement in economics and finance. Most of the known statistical inferential methods devoted to the Sharpe ratio are based on the assumption that the data are normally distributed.

A Sharpe-ratio-based measure for currencies [PDF]
European Journal of Government and Economics, 2015 The Sharpe Ratio offers an excellent summary of the excess return required per unit of risk invested. This work presents an adaptation of the ex-ante Sharpe Ratio for currencies where we consider a random walk approach for the currency behavior and ...

Model Comparison with Sharpe Ratios [PDF]
SSRN Electronic Journal, 2017 We show how to conduct asymptotically valid tests of model comparison when the extent of model mispricing is gauged by the squared Sharpe ratio improvement measure. This is equivalent to ranking models on their maximum Sharpe ratios, effectively extending the Gibbons, Ross, and Shanken (1989) test to accommodate the comparison of nonnested models ...

Re-Evaluating Sharpe Ratio in Hedge Fund Performance in Light of Liquidity Risk
Journal of Banking and Financial Economics, 2021 This paper demonstrates how the Sharpe Ratio can be modified by altering the measure of “total risk” in the denominator of the Sharpe Ratio (i.e., the standard deviation) to include liquidity risk, a major risk for investors in hedge funds that is ...

STATISTICAL ANALYSIS OF SHARPE RATIO OF THE SHARPE RATIO OPTIMAL PORTFOLIO
Visnyk Lvivskogo Universytetu Seriya Mekhaniko-Matematychna, 2023 Summary: The paper is dedicated to statistical analysis of a sample estimator of the Sharpe ratio of the Sharpe ratio optimal portfolio. Assuming that the vector of portfolio asset returns is multivariate normally distributed the asymptotic distribution of the Sharpe ratio sample estimator is found.

How to compare market efficiency? The Sharpe ratio based on the ARMA-GARCH forecast
Financial Innovation, 2020 This paper derives a new method for comparing the weak-form efficiency of markets. The author derives the formula of the Sharpe ratio from the ARMA-GARCH model and finds that the Sharpe ratio just depends on the coefficients of the AR and MA terms and is
