aa_objective_min_risk: Objective for finding minimum risk portfolio

In rexmacey/TaxAwareAA: Tax Aware Asset Allocation

Description

An asset allocation objective function calculating -100 times pretax risk less penalties. The -100 factor is to turn a minimization problem into a maximization one. Penalties applied to: Non-zero weights below a threshold; risk above a risk.budget threshold; weights outside of box limits; tracking error above a threshold, the number of classes with non-zero weights below a minimum or above a maximum, and turnover above a threshold if the curx is supplied.

Usage

aa_objective_min_risk(x, cma.ta, cma, OptimizationParameters,
  verbose = FALSE)

Arguments

x	vector of initial weights at which objective is calculated
cma.ta	tax-aware cma
cma	cma
OptimizationParameters	optimization parameters
verbose	FALSE (default) indicates only the objective value is returned; TRUE also returns penalties and other information

Value

list - wtdreturn: weighted return (after-tax, pre-tax), penalties: value of penalties, objectivevalue: objective value
