Index Funds and ETFs are two popular methods of passive investing. Passive investing is an approach which generates returns through investing in stock and bond market indices. They are contrasted with active investing of the likes of mutual funds, pension funds and ULIPs. The fund manager of an actively managed fund aims to outperform a chosen index through regular buying and selling of securities. Returns from active funds could be higher or lower than the index. In contrast, a passively managed fund aims to mimic an index. It aims to maintain the same stocks and weights as its index. Returns from these funds are at par with the index or market returns.
