  • System and method for providing optimization of a financial portfolio using a parametric leptokurtic distribution
    Patent number: 7711617
    Abstract: A system and method for providing optimization of a financial portfolio using a parametric leptokurtic distribution is presented. One or more risk factors associated with a plurality of financial assets maintained in a portfolio and applicable over at least one time horizon are provided. A subordinated parametric distribution model having leptokurtic behaviors is specified for the risk factors with a measurement of risk expressed as a function of expected tail loss for a significance level or quantile. The subordinated distribution model is applied at each such time horizon to determine a distribution of the risk factors for the financial assets. Portfolio weights providing a substantially maximum risk adjusted return for the portfolio are determined.
