# A Simplified Model for Portfolio Analysis

@article{Sharpe1963ASM, title={A Simplified Model for Portfolio Analysis}, author={William F. Sharpe}, journal={Management Science}, year={1963}, volume={9}, pages={277-293} }

This paper describes the advantages of using a particular model of the relationships among securities for practical applications of the Markowitz portfolio analysis technique. A computer program has been developed to take full advantage of the model: 2,000 securities can be analyzed at an extremely low cost--as little as 2% of that associated with standard quadratic programming codes. Moreover, preliminary evidence suggests that the relatively few parameters used by the model can lead to very… Expand
