Portfolio Analysis

Analyze portfolio for returns variance and covariance, simulate correlation of assets, calculate portfolio value at risk (VaR)

Portfolio managers concentrate their efforts on achieving the best possible trade-off between risk and return. For portfolios constructed from a fixed set of assets, the risk/return profile varies with the portfolio composition. Portfolios that maximize the return, given the risk, or, conversely, minimize the risk for the given return, are called optimal. Optimal portfolios define a line in the risk/return plane called the efficient frontier. For information on portfolio optimization, see Portfolio Optimization Functions.
