How is investment in a mutual fund different from a bank deposit?
When you deposit money with the bank, the bank promises to pay you a certain rate of interest for the period you specify. On the date of maturity, the bank is supposed to return the principal amount and interest to you. Whereas, in a mutual fund, the money you invest, is in turn invested by the manager, on your behalf, as per the investment strategy specified for the scheme. The profit, if any, less expenses of the manager, is reflected in the NAV or distributed as income. Likewise, loss, if any, with the expenses, is to be borne by you.
