Converts output of optimize.portfolio to a list of the portfolio weights, mean, volatility and Sharpe Ratio.

opt.outputMvoPCRA(
  opt,
  returns,
  digits = NULL,
  itemNames = NULL,
  annualize = TRUE,
  frequency = "monthly",
  rf = 0
)

Arguments

• opt: List output of optimize.portfolio
• returns: Multivariate xts object of portfolio assets returns
• digits: Integer number of significant digits with default NULL
• itemNames: character vector of use-supplied names for portfolio weights, mean, standard deviation and Sharpe Ratio
• annualize: Logical with default TRUE
• frequency: Returns frequency: "monthly", "weekly" or "daily", with default "monthly"
• rf: Numeric value of risk-free rate with default 0.0

Returns

A list containing the portfolio numeric weights, mean value, standard deviation and Sharpe Ratio, with default names Wgts, Mean, StdDev, and SR, or user-supplied names as a character vector value for the argument itemNames.

Details

This function uses the weights returned by optimize.portfolio, along with the portfolio monthly, weekly or daily assets returns, and a risk-free rate, to compute the portfolio mean return, volatility, and Sharpe Ratio. By default the latter three are annualized, but the user may choose to return non-annualized performance values.
