Adjusted Sharpe ratio of the return distribution

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.

AdjustedSharpeRatio(R, Rf = 0, ...)

Arguments

R	an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns
Rf	the risk free rate
…	any other passthru parameters

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
