1. A computer-implemented method for automatically identifying peer securities for a first security based on a degree of analyst coverage overlap, the method comprising: identifying, on a server computer, one or more analysts that cover the first security; determining, on the server computer, any other securities that at least one of the identified analysts cover in addition to the first security; generating, on the server computer, a set of candidate peer securities for the first security, wherein the set of candidate peer securities include each of the other securities that at least one of the identified analysts cover in addition to the first security; determining, on the server computer, the degree of analyst coverage overlap for each of the other securities in the set of candidate peer securities, wherein the degree of analyst coverage overlap for each respective other security in the set of candidate peer securities is based on a number of the identified analysts that cover the respective other security; determining, on the server computer, a set of peer securities for the first security based on the degree of analyst coverage overlap determined for each of the other securities in the set of candidate peer securities, wherein the set of peer securities includes a subset of the other securities in the set of candidate peer securities; and storing the set of peer securities determined for the first security in a database coupled to the server computer.
