The fundamental tenet of index funds and other passive investment strategies is that they will deliver returns comparable to those of a benchmark. The stocks that make up benchmark indexes are representative of the market as a whole and their performance relative to it.

Systematic risks can be seen in the way an index reflects its composition. They aren’t at risk of facing any unique or unexpected problems. Therefore, for the ordinary retail investor, just half of the market risk is there. Also read about hedge funds to understand the overall funds in the financial markets.

What is an Index Fund?

Mutual funds and ETFs can be classified as “index funds” if their portfolio is designed to mimic or track a certain financial market index, such as the Standard & Poor’s 500 Index (S&P 500). Mutual funds that track an index are often recommend because of their diversification, minimal fees, and stability. These funds will not deviate from their benchmark index regardless of market conditions.

Individual retirement accounts (IRAs) and 401(k)s are commonly held to benefit most from having these funds as their primary investment. One of the best investors of all time, Warren Buffett, has recommended index funds as a secure retirement savings option. He has argued that the average investor is better off purchasing an index fund that offers cheap exposure to all 500 companies in the S&P 500.

How Does an Index Fund Functions?

Indexing is an example of hands-off financial management. A fund’s portfolio manager may opt to create a portfolio whose holdings are identical to those in a given index rather than actively stock picking and market timing, which involves selecting assets to invest in and deciding when to buy and sell them.

If the fund’s profile is similar to that of the index, which represents the stock market as a whole or a sizable subset of it, then the fund should perform similarly to the index. There is both an index and an index fund for nearly every market in the world’s economy. Most index funds in the United States track the S&P 500.

Many people, however, also rely on other indexes, such as: The whole bond market in the United States is followed by Bloomberg’s U.S. Aggregate Bond Index. The 3,000 Nasdaq-traded equities that make up the Nasdaq Composite Index. The DJIA tracks the performance of thirty of the world’s largest publicly traded firms. The Wilshire 5000 Total Market Index represents the majority of U.S. stocks. Foreign stocks from Europe, Australasia, and the Far East make up the MSCI EAFE Index.

An index fund that mimics the Dow Jones Industrial Average, for instance, would buy shares in the same 30 big public businesses that make up the DJIA. When their corresponding benchmark indexes shift, the only time index funds’ holdings undergo significant alterations. Fund managers may make periodic adjustments to the weights allocated to individual securities if the fund tracks a weighted index.

In order to prevent any one holding from dominating an index or portfolio, weighting is used. Index ETFs, like index mutual funds, generally follow certain market indices. Still, some investors may find them more convenient due to their greater marketability and lower costs.

Example of Index Funds

Index funds have been available to investors since the 1970s. Passive investing’s rising popularity, the allure of low fees, and the prolonged bull market all contributed to a significant increase in the 2010s.

The original fund, launched by Vanguard chair John Bogle in 1976, is currently among the finest options due to its low expense ratio and consistent long-term performance. The composition and performance of the Vanguard 500 Index Fund have closely tracked those of the S&P 500. The average annual return for the S&P 500 as of June 2021 was 7.86%, while the average annual return for Vanguard’s Admiral Shares was 7.84. The minimum investment is $3,000 and the cost is 0.04%.

Factors should you Consider as an Investor?

Except for a marginal differential known as “tracking error,” the results are virtually identical to the benchmark. The objective of the fund manager is to make as few of these mistakes as feasible. When deciding whether or not to invest in index fund, it’s important to consider the following:

Capital Expenditures

Index funds are typically offered at no additional cost over their benchmarks’ expense ratios. This is because the management of an index fund does not need to devise a strategy for making investments. But keep in mind that a fund with a lower expense ratio doesn’t guarantee a higher return.

Comfort with Uncertainty

Index funds are less vulnerable to the hazards and volatility of the stock market because they track a specific market index. When the market is rising, the best gains can be obtain by purchasing these funds. But if the market were to fall, things may get worse because these funds often decline in value along with the market. Because of this, it is recommend that investors include both actively managed and index funds in their portfolios.

Calculating the Returns

Index funds aim to replicate the performance of a market index. In contrast to actively managed funds, these ones don’t aim to outperform a certain index. It’s possible that the returns will deviate from the index they’re suppose to reflect, though, due to tracking issues. If there are fewer mistakes, the index fund will do better.

Duration of an Investment

Index fund can experience substantial volatility over relatively brief periods of time. Long-term, these alterations may eat away at your investment’s profits. As a result, anyone looking to invest over the long term would benefit most from index fund. You need patience if you want to invest in index funds and let them grow to their full potential.

Taxation on Index Funds

You will be subject to capital gains taxation when you sell your investment in an index fund. The longer you keep your money invested, the less tax you will owe. Gains realized in less than a year are consider STCG, and are subject to a 15% tax rate (plus any relevant surcharge and 4% Health & Education cess).

If you make more than 1,00,000 in long-term capital gains (LTCG) from equity-oriented mutual funds or equity shares in a year, you’ll owe tax at the rate of 10% (plus any relevant surcharge + 4% Health & Education cess).


Because investors are skeptical that their mutual fund managers will maximize their returns, there has been a rise in the popularity of passively managed products such as index funds. If you’re considering investing in index funds, you should read this article first.
