Informal; a mutual fund that invests predominantly or exclusively in high growth companies. Because many of these companies will eventually go bankrupt, a go-go fund carries high risk. However, it has the possibility of a high return if some of the companies establish themselves and become highly profitable.
An investment company that concentrates on short-term investment performance through frequent trading of highly speculative securities. Such funds were very popular during the late 1960s but lost favor following the market decline of the early 1970s that produced large price drops in the types of stock held by the go-go funds.
