ActivePremium: Active Premium or Active Return

In tsungwu/JFE: Tools and GUI for Analyzing Time Series Data of Just Finance and Econometrics

Active Premium or Active Return

Description

The return on an investment's annualized return minus the benchmark's annualized return.

Usage

ActivePremium(Ra, Rb, scale = NA, ...)

Arguments

Ra	return vector of the portfolio
Rb	return vector of the benchmark asset
scale	number of periods in a year (daily scale = 252, monthly scale = 12, quarterly scale = 4)
...	any other passthru parameters to Return.annualized (e.g., geometric=FALSE)

Details

Active Premium = Investment's annualized return - Benchmark's annualized return. With a view to speeding computation. I re-write the code of some ratios of the package PerformanceAnalytics, and use the same name for comparing the performance enhancing. Interested readers may compare speed improvement with the use of system.time().
