Patent number: 8751357Abstract: Embodiments of the invention are directed to a system, method, or computer program product for evaluating risk adjusted performance of an investment portfolio. This invention may be applied to any asset which has a value. The invention evaluates risk adjusted performance of an investment portfolio by first determining at least one positive utility concept and at least one negative utility concept describing an asset. Then, the invention normalizes the at least one negative utility concept to an equivalent negative utility concept describing or deriving from a group of assets. Finally, the invention may relate at least one positive utility concept and at least one normalized negative utility concept to determine a performance measure. In this way, the invention normalized negative asset returns such that better investor utility ratings are not falsely provided.Type: GrantFiled: February 16, 2012Date of Patent: June 10, 2014Assignee: University Court of the University of St AndrewsInventor: Andreas G.
