AdjustedSharpeRatio {JFE}

Adjusted Sharpe ratio of the return distribution

Description

Adjusted Sharpe ratio was introduced by Pezier and White (2006) to adjusts for skewness and kurtosis by incorporating a penalty factor for negative skewness and excess kurtosis.

Usage

AdjustedSharpeRatio(R, Rf = 0, FUN = "StdDev")

Arguments

R

an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns

Rf

the risk free rate

FUN

one of "StdDev" or "VaR" or "ES" to use as the denominator for unadjusted Sharpe ratio, default="StdDev"

Details

Adjusted Sharpe Ratio = SR * [1 + (\frac{S}{6}) * SR - (\frac{K - 3}{24}) * SR^2]

where SR is the sharpe ratio with data annualized, S is the skewness and K is the kurtosis
