A Tracker is the name given to a Fund which invests in the shares of one or more Stockmarket indices. The shares are often bought and managed through a computer program. The aim of such a fund is to track (follow) the Index or indices( Stockmarket/s) as closely as possible. Such Funds have no one managing the fund and the process is largely automated.
