MSquaredExcess: M squared excess of the return distribution

Description Usage Arguments Details Author(s) References Examples

Description

M squared excess is the quantity above the standard M. There is a geometric excess return which is better for Bacon and an arithmetic excess return

Usage

1
MSquaredExcess(Ra, Rb, Rf = 0, Method = c("geometric", "arithmetic"), ...)

Arguments

Ra

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

Rb

return vector of the benchmark asset

Rf

risk free rate, in same period as your returns

Method

one of "geometric" or "arithmetic" indicating the method to use to calculate MSquareExcess

...

any other passthru parameters

Details

MSquared excess (geometric) = (1+M^2)/(1+b) - 1

MSquared excess (arithmetic) = M^2 - b

where M^2 is MSquared and b is the benchmark annualised return.
