A special type of fund within equities is the equity-linked savings scheme (ELSS), in which investments qualify for tax deduction under Section 80C of the Income Tax Act. Then there are closed-end funds that have a defined investment time period. In closed-end funds, one can invest only at the time of launch of these funds and withdraw only when the fund is finally closed.In contrast, open-ended schemes are open for investment and redemption on a continuous basis till the scheme is wound up—investors can invest their money at any point of time. Investors can also redeem their money at any point of time subject to applicable exit load, if any, applicable to a scheme. Likewise, there are also funds that are actively managed and those that are passive as they track the constituents of a popular index. Once you know which fund falls under which category, it would help you choose a scheme based on your risk profile and investment needs.
