## Efficient portfolio

A portfolio that provides the greatest expected return for a given level of risk (i.e., standard deviation), or, equivalently, the lowest risk for a given expected return.

## Markowitz Efficient Portfolio

In Markowitz Portfolio Theory, a portfolio with the highest level of return at a given level of risk. One who carries such a portfolio cannot further diversify to increase the expected rate of return without accepting a greater amount of risk. Likewise one cannot decrease his/her exposure to risk without proportionately decreasing the expected return. A Markowitz efficient portfolio is determined mathematically and plotted on a chart with risk as the x-axis and expected return as the y-axis. See also: Markowitz efficient set of portfolios, Homogeneous expectations assumption.
