A mutual fund that targets pension funds, endowments, and other high net worth entities and individuals. Institutional funds usually have lower operating costs and higher minimum investments than retail funds. Often their main objective is to reduce risk, so they invest in hundreds of different securities, which makes them among the most diversified funds available. They also do not tend to trade securities very often, so they are able to keep operating costs to a minimum. Although in the past investors typically needed at least $1 million in order to invest in an institutional fund, nowadays some discount brokers offer access to these funds for smaller amounts.
