How to Invest in Index Funds in India

26 July 2022

An important component of a successful investment portfolio is diversification. Investors try to spread their money among a variety of asset classes, including gold, real estate, debt, and equity. To reduce risks, they work to further diversify even within each asset class.

By purchasing shares of companies with various market capitalizations and sectors, you can diversify your equity portfolio, a well-known strategy for lowering risks in equity investing. Index Funds come into play here.

In this blog, we'll discuss Index Funds, how to invest in Index Funds, and how to buy Index Funds.

Index Fund Meaning

An Index Mutual Fund, as its name implies, makes investments in stocks that mimic stock market indices like the NSE Nifty, BSE Sensex, etc.

These funds are passively managed, which means the manager doesn't alter the portfolio's composition and instead invests in the same securities that are present in the underlying index in the same proportion. These funds aim to provide returns that are comparable to the index they follow.

How Do Index Funds Work? 

Let's say that an Index Fund is tracking the NSE Nifty Index. This fund will, therefore, have 50 stocks in its portfolio in similar proportions. An index can include equity and equity-related instruments along with bonds.

The Index Fund ensures that it invests in all the securities that the index tracks. While an actively managed mutual fund endeavours to outperform its underlying benchmark, an Index Fund, being passively managed, tries to match the returns offered by the underlying index.

Benefits of Investing in Index Funds

When it comes to Index Funds in India, there are numerous benefits of Index Funds that you need to know about. Some of the advantages of investing in Index Funds, India are:

  • Lower Expense Ratio and Low Fees

Index funds typically have lower expense ratios than actively managed mutual funds, which means that you can invest more of your money where it will do the best for your portfolio.

  • Tax Benefits

Since Index Funds are passively managed, they don't buy and sell individual securities as frequently as actively managed mutual funds do. This reduces their tax liabilities and increases your after-tax returns over time. 

  • Easy to Manage

Index Funds are also easier to manage than actively managed mutual funds because they don't change their asset allocation easily.

This means that once you invest in an Index Fund, its asset allocation remains the same until the time when you decide to change it yourself or until another manager takes over from your current one.

  • Impartial Investing

Index Funds invest using an automated, law-based process. The amount to be invested in index funds of different securities is specified in the fund manager's mandate. By doing this, human discretionary bias in investment decisions is eliminated.

Things Investors Should Consider Before Investing in Index Funds

Here are a few things an investor must consider while finding answers for how to invest in index funds India- 

  1. Risks and Returns

Since index funds track a market index and are passively managed, they are less volatile than actively managed equity funds. Hence, the risks are lower. During a market rally, index funds India returns are usually good.

However, it is usually recommended to switch your investments to actively managed equity funds during a market slump. Ideally, you should have a healthy mix of index funds and actively managed funds in your equity portfolio.

Further, since the index funds endeavour to replicate the performance of the index, returns are similar to those of the index. However, one component that needs your attention is Tracking Error. Therefore, before investing in an index fund, you must look for one with the lowest tracking error.

  1. Expense Ratio

The Expense Ratio is a small percentage of the total assets of the fund charged by the fund house toward fund management services.

One of the biggest USPs of an index fund is its low expense ratio. Since the fund is passively managed, there is no need to create an investment strategy or research and find stocks for investing. This brings the fund management costs down leading to a lower expense ratio.

  1. Invest According to Your Investment Plan

Index funds are recommended to investors with an investment horizon of 7 years or more. It has been observed that these funds experience fluctuations in the short term but they average out over the longer term.

With an investment window of at least seven years, you can expect to earn returns in the range of 10-12%. You can align your long-term investment goals with these investments and stay invested for as long as you can.

On redeeming the units of an index fund, you earn capital gains - which are taxable. The rate of capital gains tax depends on the holding period - the period for which you were invested in the fund.

  • The capital gains earned by you for a holding period of up to one year = Short Term Capital Gain (STCG) which is taxed at 15%.
  • The capital gains earned by you for a holding period of more than one year = Long Term Capital Gain (LTCG). LTCG up to Rs. 1 lakh is not taxable. Any LTCG above this amount is taxed at the rate of 10% without indexation benefits.

Additionally, it is simple to be drawn into the volatile world of day trading, where you buy and sell stocks every day in an effort to make large profits by betting on swift price changes.

How to Invest Smartly in Index Funds?

Cost is often the deciding factor in the selection of an Index Fund. One of the biggest benefits of index funds is their low costs. They are inexpensive to run because they are automated to track changes in an index's value.

But don't automatically assume that all index mutual funds are affordable. They incur administrative costs even though they aren't actively managed by a group of highly compensated analysts. The returns to each fund shareholder are deducted as a percentage of their total investment for these expenses.

The last step is to choose an index fund that fits your financial objectives.

How Many Index Funds Should You Own?

It is recommended to have one fund in each of the three categories: large, mid, and small-cap. As a general rule, you should not have more than two funds in the same theme/market cap. You'll do fantastic things with just one fund. If necessary, extend it to two but not beyond that.

Is It a Good Time to Invest in Index Funds?

If you intend to invest for the long term, market lows and highs become less important. If you're concerned about buying an index fund at a high, remember that if you hold it for a long time, that high will appear much smaller.

Is It Possible to Lose Money in An Index Fund?

An index fund, like any other investment, can lose money, but if you invest in one and hold it for a long period of time, your investment is much more likely to grow in value. You may then be able to recoup your investment.

Can Index Funds be Considered a Good Investment?

The majority of experts concur that index funds make excellent long-term investments. They are affordable options for getting a portfolio that passively tracks an index and is well-diversified.

To ensure that you are tracking the best index for your objectives at the most affordable price, make sure to compare various index funds or ETFs.
