What Are Index Funds And How Do They Work? (2024)

For the majority of investors, being successful means outperforming the market itself. While many investors, especially newer ones, strive to make their portfolios outperform the market, it’s not always the case, nor is it realistic. How do investors stay at least in line with the curve, if not ahead of it? This is where index funds come in.

What Are Index Funds?

Index funds are a portfolio of stocks or bonds that impersonate the performance of a financial market index. They replicate a portion of the stock market or, in some cases, the market itself.

To understand this fully, let’s first understand how an index works. An index is a way to track and analyze the performance of a certain group of securities or assets in the market. Indexes are used to measure data like inflation, interest rates, among others and they’re often used to establish benchmarks or standards of performance for the portion of the market being mimicked.

Think of it as a small, architecture scale model of a full-sized building. This small-scale model is essentially the portion of the market that is being tracked, mimicking the original in proportions.

For example, if an index fund is tracking the NSE Nifty Index, this fund will have a total of 50 stocks in its portfolio and each of these 50 stocks would be given a certain weightage by the stock market, replicating the proportions of the index. As such, the performance of the index fund would be based on the performance of the actual stocks in the market.

Index funds are also known to be key when it comes to portfolio diversification, a strategy where you spread your investments across different types of assets and securities in order to balance out or mitigate the risk an investor takes on. When an investor purchases an index fund, they are exposed to many different kinds of stocks in the market.

Types of Index Funds

Before we dive into which kind of investor/s must invest in Index funds, let’s skim through the different types of Index funds.

  • Broad market index funds: Broad market funds mimic a large section of the stock market. Index funds like this generally have the least expenditure while also being incredibly tax-efficient, making them popular with investors who want a large variety of stocks and bonds.
  • International index funds: Essentially, global index funds are based on indexes that are not limited to any country or stock market, giving the investor exposure to international companies in emerging markets and more.
  • Earnings-based index funds: These are index funds that are based on the profits generated by companies, and these are further broken down into two kinds of indices: growth and value. Growth indexes are made up of companies that will generate profits faster than others in the market while value indexes contain stocks of companies that are trading at a lower cost compared to how much the company is earning.
  • Bond-based index funds: These are index funds that invest solely in a combination of short, intermediate, and long-term bonds. Such a combination not only helps you diversify your investment portfolio but also yields steady and healthy returns month-on-month. Investing in funds like this is popular amongst investors looking to generate a monthly income.

Should You Invest in Index Funds?

Before you decide to invest in index funds, it is important to assess your risk appetite, your pre-decided investing strategies, and the duration of your investment.

For those with low-to-medium risk appetite.

If you’re someone who has a small-to-medium risk appetite and would prefer playing it somewhat safe, then index funds are the right fit for you.

For those who want to invest in the stock market passively.

Since index funds reflect a section of the stock market or the market itself, the returns from these funds basically match the market’s performance, they are passively managed by fund managers rather than the investment being strategically and actively managed by a manager to bring in higher returns.

As a result, they consist of lower expenses and fees when compared to actively managed funds and hence are a great option for new investors.

For those who want to invest less amount of time in investing.

It is important to recognize the amount of time you can or want to dedicate to investing, researching, and keeping up to date with the market. If you’re someone who wants to keep investing with a predictable rate of return and not too much hassle, then index funds may work for you.

Generally, actively managed funds are better for more seasoned investors or those who can dedicate the time to learning the ropes of investment. If you’re someone who doesn’t want predictable returns, seeks to outperform the market, and is comfortable taking on a considerable amount of risk, then actively managed funds are more appropriate for you since these funds are handled by a fund manager who will make predictions on performance, assess risk, and accordingly make changes to your portfolio.

While actively managed funds are associated with fund managers, it does require some back and forth with the manager, tracking market developments, and making decisions on the go. It is also higher in cost compared to index funds.

Factors To Consider Before Purchasing Index Funds

Before diving into the ocean of index funds, it’s important to assess a couple of factors which will hopefully give you a better idea of the kind of index funds you want to invest in.

Risk With steady and consistent returns even over long periods of time, the risk associated with index funds is quite low.

However, it is not wise to have only index funds in your portfolio, especially when the market is in a slump; if anything, during a slump it is advised that you shift to investing in actively managed funds because if the market is slumping then the performance of an index fund would slump right along with it.

It’s a good practice to have a mix of index and actively managed funds as this helps you keep afloat during market slumps or help you grow your wealth faster.

Returns Returns from index funds are pretty much the same as that of the market index. Be mindful though that even the lowest risk investments can have low performance so ensure that you keep the fund’s tracking error in mind.

Tracking errors indicate the variability in the performance of the Index fund against a set benchmark (that of the market index). The tracking error is reported generally as a standard deviation percentage difference between the returns the investor receives versus what the fund was attempting to mimic.

Expense Ratio An expense ratio is a percentage of the total assets of the fund charged by the fund management for their services. With index funds, the biggest advantage is that its expense ratio is very low comparatively; if it’s not, it’s worth enquiring as to why that is.

Tax Since index funds are equity funds, it is important to remember that they are subject to taxes. When a fund house pays dividends, a dividend distribution tax of 10% is deducted at the source before making the payment to investors.

Upon redeeming the units of an index fund, you will earn capital gains, which are subject to capital gains tax. The rate of tax depends on the period for which you invested in the fund, commonly known as a holding period.

Invest based on your goals Index funds perform better over a longer period of time so it is advisable to invest for a minimum of seven years. This allows you to yield maximum returns as per the market index. Therefore, the long-term nature of the investment must be taken into consideration before investing to see if this matches your financial and investment goals.

For example, if you’re looking to generate higher returns over a shorter period of time, this might not be the best strategy for you right now and that’s okay since there are always other options available.

Bottom Line

Index funds are a great way to get a taste of the stock market if you’re new to investing, especially because of the low cost and effort involved. Predictable results and less volatility will serve you well if you are averse to high-risk investing.

It is much easier to invest in general because of the information available online so make sure that you do some in-depth research on index funds and the fund managers associated with them before you jump in.

Take your time to assess the compatibility of this kind of investment with your financial goals. Ultimately, with index funds, it’s best to think about your long-term returns and financial security and go in for the long haul.
