Examples and How To

Estimate Efficient Portfolios for Entire Efficient Frontier for Portfolio Object

The most basic way to obtain optimal portfolios is to obtain points over the entire range of the efficient frontier.

Obtaining Endpoints of the Efficient Frontier

Determine the range of returns from minimum to maximum to refine a search for a portfolio with a specific target return.

Obtaining Efficient Portfolios for Target Returns

To obtain efficient portfolios that have targeted portfolio returns, use the estimateFrontierByReturn function.

Obtaining Efficient Portfolios for Target Risks

To obtain efficient portfolios that have targeted portfolio risks, use the estimateFrontierByRisk function.

Efficient Portfolio That Maximizes Sharpe Ratio

Portfolios that maximize the Sharpe ratio are portfolios on the efficient frontier that satisfy several theoretical conditions in finance.

Estimate Efficient Frontiers for Portfolio Object

Given any portfolio, the functions estimatePortReturn, estimatePortRisk, and estimatePortMoments provide estimates for the return and risk.

Plotting the Efficient Frontier for a Portfolio Object

The plotFrontier function creates a plot of the efficient frontier for a given portfolio optimization problem.

Asset Allocation Case Study

This example shows how to set up a basic asset allocation problem that uses mean-variance portfolio optimization with a Portfolio object to estimate efficient portfolios.
