Efficient set Efficient setGraph representing a set of portfolios that maximize expected return at each level of portfolio risk.Markowitz Efficient FrontierA graphical representation of the set of portfolios giving the highest level of expected return at different levels of risk. Harry Markowitz theorized that each level of risk contains one combination of assets giving the highest expected return. An efficient set of portfolios is represented as a line on a graph with risk as the x-axis and expected return as the y-axis; this representation is the Markowitz efficient frontier.
