PMinCDaR {FRAPO}

Portfolio optimisation for minimum conditional draw down at risk

Description

This function returns the result of a long-only portfolio optimization whereby the portfolio's (historic) conditional draw down at risk is minimized.

Usage

PMinCDaR(PriceData, alpha = 0.95, softBudget = FALSE, ...)

Arguments

PriceData

A rectangular array of price data.

alpha

Numeric, the confidence level for which the conditional draw down shall be computed.

softBudget

Logical, whether the budget constraint shall be implemented as a soft constraint, i.e. the sum of the weights can be less than one. The default is to use an equality constraint.

...

Arguments are passed down to Rglpk_solve_LP

Details

This function implements a long-only portfolio optimisation for a minimum conditional draw down at risk (see references below). The problem can be stated in the form of a linear program and GLPK is used as solver.

Value

An object of formal class "PortAdd".

Note

A warning is issued in case the solver had exit status not equal to zero.
