Portfolio Analysis and Modern Portfolio Theory

Square of correlation coefficient

A portfolio is a collection of investment vehicles assembled to meet one or more investment goals. Primary objectives include growth-oriented, income-oriented, and capital preserving portfolios.

An efficient portfolio is one that provides the highest return for a given level of risk. Investors will choose the investment with the highest potential return for a given level of risk or the one with the least risk for a given return.
