An index fund is a mutual fund that imitates the portfolio of an index. These funds are also known as index-tied or index-tracked mutual funds. Let us explore index funds in detail through the following topics.

1. What is an Index Fund?

Many investors are aware of the benefits of diversifying their portfolio across assets. Index funds often catch their eyes in this search as they refer to funds that invest in a broader market index – like the Sensex or the Nifty. All the stocks in these indices will find some representation in their investment portfolio. This theoretically ensures a performance identical to that of the index which is being tracked. Low expense ratio is its main USP.

2. How do Index Funds Work?

When an index fund tracks a benchmark like the Nifty, its portfolio will have the 50 stocks that comprise Nifty, in the same proportions. An index is a group of securities defining a market segment. These securities can be bond market instruments or equity-oriented instruments like stocks. Some of the most popular indices in India are BSE Sensex and NSE Nifty. Since index funds track a particular index, they fall under passive fund management. The fund manager decides which stocks have to be bought and sold according to the composition of the underlying benchmark. Unlike actively-managed funds, there isn’t a standalone team of research analysts to identify opportunities and select stocks.

While an actively-managed fund strives to beat its benchmark, an index fund’s role is to match its performance to that of its index. Index funds typically deliver returns more or less equal to the benchmark. However, there can be a small difference between fund performance and the index. This is referred to as the tracking error. The fund manager must work towards bringing down the tracking error as much as possible.

3. Who should Invest in Index Funds?

The investment decision in a mutual fund solely depends upon your risk preferences and investment goals. Index funds are ideal for investors who are risk-averse and expect predictable returns. These funds do not require extensive tracking. For example, if you wish to participate in equities but don’t wish to take risks associated with actively-managed equity funds, you can choose a Sensex or Nifty index fund. These funds will give you returns matching the upside that the particular index sees. However, if you wish to earn market-beating returns, then you can opt for actively-managed funds.
The returns of index funds may match the returns of actively-managed funds in the short run. However, the actively-managed fund tends to perform better in the long term.

4. Things to Consider as an Investor

Risk tolerance

Since index funds map an index, they are less prone to equity-related volatility and risks. Investing in index funds is an excellent option if you wish to generate high returns amid a rallying market. However, you will have to switch to actively-managed funds during a market slump. Index funds tend to lose their value during a market downturn. Hence, it is advised to have a mix of actively-managed funds and index funds in your portfolio.

Return factor

Unlike actively-managed funds, Index funds track the performance of the underlying benchmark passively. These funds do not aim to beat the benchmark but just to replicate the performance of the index. However, the returns generated may not be at par with that of the index due to tracking errors. There can be deviations from actual index returns.

Hence, it is advised to shortlist funds with minimum tracking error before investing in an index fund. The lower the errors, the better the performance of the fund.

Cost of investment

Index funds usually have an expense ratio of 0.5% or even less. In comparison, actively-managed funds have an expense ratio of 1% to 2.5%. The portfolio of the index funds need not be passively managed, and the fund manager is not required to formulate any investment strategy. Hence, the difference in the expense ratio.

If two index funds are tracking the Nifty, both will generate similar returns. The only difference will be the expense ratio. The fund which has a lower expense ratio will generate comparatively higher returns on investment.

Investment horizon

Index funds, generally, suits individuals with a long-term investment horizon. Usually, the fund experiences many fluctuations during the short-run, which averages out in the long-run, say, more than seven years to generate returns in the range of 10%-12%. Those who choose index funds must be patient enough to stick around for at least that long. Only then can the fund perform at its full potential.

Financial goals

Equity funds can be ideal for achieving long-term financial goals like wealth creation or retirement planning. Being a high risk-high return haven, these funds are capable of generating enough wealth, which may help you retire early and pursue your passion in life.

Tax on gains

When you redeem units of index funds, you earn capital gains, which is taxable. The rate of taxation depends on how long you stayed invested in index funds, i.e., the holding period.

Capital gains you make during the holding period of up to one year are called short-term capital gains (STCG). STCG is taxed at a rate of 15%. Similarly, capital gains you earn after a holding period of more than one year are called long-term capital gains (LTCG). LTCG over Rs 1 lakh is taxed at 10% without the benefit of indexation.
