Minimum variance portfolio

PrepNuggets

The portfolio with the minimum variance for each given level of expected return. For example, if an investor has a required return of 8%, he would choose a portfolio which has the lowest risk amongst all the other portfolios with expected returns of 8%.  We call these the minimum-variance portfolios, and together at various levels of portfolio returns, they make up the minimum variance frontier.
