Abstract: A system for forming and managing online investment clubs utilizes the features of an online social network to provide advantages in the operation of such online investment clubs. The system permits users to follow and assess the investment skill of other investors in their own or other investment clubs and to follow such individuals' future investment decisions and those of other investment clubs. Unlike in existing investment clubs, the system maintains a constant real time evaluation of each user's investment decisions whether or not they were followed by the club, and ranks that valuation against all other users. The evaluation of each user's investment decision also provides the necessary information for the platform to compile various performance metrics of the individuals.
