What is an Index fund?
An index fund is a type of mutual fund whose objective is to track and mimic the composition and performance of an underlying index of securities, at as low tracking error as possible. An index is a basket of securities – can be stocks or debt instruments, that represent a specific theme or category of the market.
Different indices are drawn up by the stock exchanges from time to time to represent different market segments and to serve as benchmarks for several financial analysis. For example – the NIFTY 50 Index represents the top large cap companies on the market, on the other hand the NIFTY Small Cap 50 Index represents the top 50 companies in the small cap segment. An index fund follows a passive investing strategy so as to provide investors with returns that align with returns earned by the underlying index being tracked.
How do index funds work?
Index funds follow a passive investing model. The fund manager invests the fund’s corpus in the same securities and in the same proportion as are found in the underlying index.
Indices are re-balanced and re-constituted periodically. In line with this the fund manager also re-aligns the fund’s portfolio composition by selling outgoing securities and buying incoming securities of the index.
Through this strategy, index funds look to earn returns similar to those returned by the underlying index, subject to tracking errors.
Why can index funds be a good investment choice?
Index funds offer several benefits to its investors, which include:
- Single access point to diversified securities of a specific theme
Index funds give portfolio exposure to a diversified cross-section of securities that are found in the index through a single investment tool.
- Periodic rebalancing - Follows ‘principle of natural selection’
By tracking a market-driven index, these funds allow market behaviour to govern stock selection. This keeps you invested in top movers of the market through a passive investing model.
- Reduced active stock selection risk
By simply tracking the index, these funds eliminate the element of human bias in stock selection, thus it is not susceptible to ‘active stock selection risk’
- Liquidity
With no entry load and generally no exit load (typically nil after 90 days), investments in index funds offer investors liquidity throughout the tenure of the fund. Their units can in fact be bought and sold through both regular and direct plans.
- Low minimums
Like most mutual funds, index funds give wide portfolio access at low minimum investments – as low as Rs.500.
- Reduced investing costs
A passive investing strategy allows index funds to have a low total expense ratio, reducing the cost of investing.
Who are index funds best suited for?
Index funds are suitable for:
- Investors looking to minimise active stock selection risk and incur lower costs than actively managed mutual funds
- Investors, especially novice investors looking to earn market-linked returns that are more or less at par with those earned by the index
- Investors looking to invest in a specific segment or theme without taking on the hassle of active stock selection
