If Cole successfully analyzes an opportunity for the hedge fund and it invests slightly more effectively, that will be a win for the fund’s managers and its investors. But there will very likely be an equivalent loss on the other side of the investment (whoever sold it to them makes out slightly less well for having undervalued the asset). It’s not clear what the macroeconomic benefit is, unless you either favor the hedge fund’s investors over others or have a very abstract view toward capital markets working efficiently.
