While Indians love to invest in physical gold, even mutual funds offer the option, but in paper format. In India, gold funds are, typically, of two types—gold exchange-traded funds (ETFs) and gold fund of funds (FoFs). Gold ETFs track the price of gold and are backed by actual gold bullion, while gold FoFs invest in gold ETFs. A third type is World Gold FoF. It invests in stocks of companies involved in gold mining and production.
