Since then, in addition to eventually earning Markowitz the 1990 Nobel Prize in Economics , modern portfolio theory would come to be one of the most popular investment strategies in use today—more than 67 years later.

The Modern Portfolio Theory is based on following assumptions: i. The traditional theory of portfolio postulates that selection of assets should be based on lowest risk, as measured by its standard deviation from the mean of expected returns. This is because the securities are potentially correlated. In the second, the Shapley value is used to build a unique approach to portfolio selection using what the author calls an optimization game. Markowitz' Portfolio Selection Theory 3. The traditional portfolio selection model seriously overestimates its theoretic optimal return. In that case, we have all the inputs for the above equation, except for the correlation coefficient.
