Index Fund Investing: A Passive Approach ToLong-Term Wealth

Index Fund Investing

Diversification, a key element in building a resilient investment portfolio, is crucial for mitigating risks. Investors strive to spread their money across different asset classes, including debt, equity, real estate, and gold, to reduce the impact of any single investment’s performance. Within every asset class, further diversification is pursued to minimise exposure to specific risks. A popular strategy for risk reduction in equity investing involves diversifying your equity portfolio by investments in company shares spanning various sectors and market capitalisations. That is where Index Funds come into the picture, offering a significant role in diversification. This article explores Index Funds, their working, and more.

Understanding Index Funds

Index Funds, as their name suggests, invest in stocks resembling a distinct stock market index, like the BSE Sensex or NSE Nifty. These funds are managed passively, where the fund manager replicates the index’s composition without altering the portfolio’s makeup. The primary objective behind these funds is to provide returns that nearly resemble their tracked index’s performance.

How is an Index Fund Different from an SIP?

What is SIP? It is a disciplined approach to investing in mutual funds, where investors contribute a fixed amount regularly. An index fund is a type of mutual fund that aims to replicate the performance of a specific stock market index.

Working of Index Funds

Let’s take a closer look at how an Index Fund operates. Imagine an Index Fund that is designed to replicate the NSE Nifty Index. In this scenario, the fund will hold 50 stocks in its portfolio, with proportions similar to those of the index. On the other hand, a broader market index, such as the Nifty Total Market Index, may include approximately 750 stocks across various market caps and sectors.

It’s important to note that an index can comprise equity and related instruments and bonds. The index fund ensures investing in all the securities included in the index it tracks, maintaining a balance that mirrors the index’s composition. While an active mutual fund aims to outperform its respective benchmarks, a passively managed index fund seeks to match the underlying index’s returns.

Things To Consider Before You Invest in Index Funds

Several factors should be carefully considered before you invest in Index Funds in India.

Objective and Risk Tolerance

Determine your risk tolerance and investment objectives. Index funds offer diversification and are typically less volatile compared to actively managed funds but still carry market risk.

Index Selection

Choose the index that aligns with your investment goals. Various indices are available in India, such as the NSE Nifty, BSE Sensex, and broader market indices like the Nifty 500. Select the index that best reflects the market segment you want exposure to.

Expense Ratio

Find and compare various index funds’ expense ratios. Since index funds are passively managed, their expense ratios are generally lower than those of actively managed funds. A lower expense ratio can significantly impact your long-term returns.

Tracking Error

Assess the index fund’s tracking error. It measures how closely the fund’s performance matches its underlying index’s performance. Choose funds with lower tracking errors, as they closely mimic the index’s returns.

Size of Fund and Liquidity

Consider the liquidity and fund size. Larger funds possibly have lower expense ratios and better liquidity, which can benefit investors.

Past Performance

As past performance does not indicate future results, reviewing the index fund’s historical performance may help with insights into its ability to track the index effectively.

Exit Load and Minimum Investment

Check for any exit loads or minimum investment requirements associated with the index fund. Understand the fund’s redemption process and associated costs.

Tax Implications

Realise the tax implications related to investing in index funds. Long-term capital gains on equity-oriented funds are tax-free up to a certain limit, but short-term gains are taxed flatly.


Assess the diversification benefits offered by the index fund. Index funds provide exposure to a basket of stocks within the index, offering diversification across sectors and companies.

Investment Horizon

Determine your investment horizon. Index funds are ideal for long-term investors looking for steady returns and diversification. Assess whether the investment horizon of the index fund aligns with your financial goals.


Index fund investing offers a straightforward and cost-effective way for Indian investors to participate in the equity markets while minimising the complexities and risks associated with active management. As with any investment decision, thorough research and careful consideration of individual circumstances are paramount.
