  This paper puts forward that money managers and prospective investors
exchange information and ideas about assets directly through word-of-mouth
communication. This, in turn, affects the performance of the mutual funds and
their respective managers. We develop a novel "Epi-Finance" model that connects
epidemiology and finance to provide a solid explanation behind information
transmission in the fund industry. By considering factors such as location,
race, gender, and education concerning the equity market, several claims and
connections are observed and modeled using an epidemic model. For example,
based on location, a mutual fund manager is likelier to buy (or sell) a
particular equity at any time if other managers in the
{\epsilon}-neighborhoods({\epsilon}>0) are buying (or selling) that same
equity. If the information about that particular equity spreads fast and the
communication network is well connected, the same pattern shows up even when
the fund managers are far apart. Also, a male fund manager is likelier to
relate his investment style to other male managers, which is true otherwise.
The same fashionable results are expected on race education, among others with
special contextual differences.
