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

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
