What is an index fund?

An index fund is a mutual fund that aims to match the performance of a specific market index instead of trying to beat it. The fund manager invests in the same securities as the benchmark index and generally in the same proportion.

For example, a Nifty 50 index fund invests in the companies that make up the Nifty 50 Index. If the index changes, the fund portfolio is also updated to reflect those changes.

Since index funds simply follow an index, they usually have lower portfolio turnover than actively managed funds. However, returns are still market-linked and are never guaranteed.

When you invest in an index fund, you receive mutual fund units based on the applicable NAV (Net Asset Value). NAV is calculated once every trading day after market hours.

You can invest in index funds through:

  • SIP (Systematic Investment Plan) 
  • Lumpsum investment 

On the Bajaj Broking website, you can choose from 4,000+ mutual fund schemes across multiple categories after completing your mandatory KYC.

Which types of index funds can you invest in?

India offers different types of index funds for different investment needs. Some focus on the overall market, while others track sectors, bonds or international markets.

Type of index fundWhat it tracksRisk levelSuitable for
Broad market index fundNifty 50, Sensex, Nifty Next 50 and similar indicesModerate to HighLong-term investors seeking market-wide exposure
Equal-weight index fundEqual allocation to every stock in an indexModerate to HighInvestors looking for better diversification
Sectoral index fundBanking, IT, Pharma, FMCG and other sectorsHighInvestors with a positive view on a particular sector

International index fundOverseas market indicesModerate to HighInvestors looking for global diversification
Debt index fundGovernment securities or bond indicesLow to ModerateConservative investors seeking relatively stable returns
ESG index fundCompanies selected using Environmental, Social and Governance criteriaModerate to HighInvestors who prefer responsible investing

1. Broad market index funds

These funds track popular benchmark indices such as the Nifty 50 or Sensex. They provide exposure to large companies across different sectors and are suitable if you want to mirror the overall market.

2. Equal-weight index funds

Unlike traditional market-cap-weighted indices, equal-weight index funds assign the same weight to every stock. This reduces concentration in a few large companies and offers broader diversification.

3. Sectoral index funds

These funds invest only in companies from one industry, such as banking, IT or healthcare. They can deliver higher returns when that sector performs well but may also experience larger losses during downturns.

4. Thematic index funds

Thematic funds track companies connected by a common investment idea, such as infrastructure, manufacturing or digital technology. Since they focus on a single theme, they carry higher risk than diversified index funds.

5. Mid-cap index funds

These funds follow indices made up of medium-sized companies. They may offer higher growth potential than large-cap funds but generally experience greater price fluctuations.

6. Small-cap index funds

Small-cap index funds invest in smaller listed companies through a market index. They can generate strong long-term growth but usually come with higher volatility and risk.

7. International index funds

These funds track foreign stock market indices. They help diversify your portfolio across countries and reduce dependence on the Indian market alone.

8. Debt index funds

Debt index funds invest in bonds and fixed-income securities that form part of a debt index. They generally carry lower risk than equity index funds, although returns remain market-linked.

9. ESG index funds

ESG index funds track companies selected using Environmental, Social and Governance standards. They are suitable if you want your investments to align with responsible business practices while following a passive investment strategy.

Why do investors choose index funds?

Index funds have become popular because they offer a simple way to invest in the stock or bond market. Instead of selecting individual securities, the fund tracks a benchmark index. This makes them suitable if you want long-term market exposure with a passive investment approach.

Before investing, always check the SEBI-mandated riskometer, which classifies schemes as Low, Low to Moderate, Moderate, Moderately High, High, or Very High based on their risk level.

BenefitWhy it matters
Broad diversificationYour investment is spread across multiple securities in the index instead of relying on one company.
Passive investingThe fund follows a benchmark index instead of trying to outperform the market.
Lower portfolio turnoverSince the portfolio changes mainly when the benchmark changes, trading activity is generally lower.
TransparencyYou can easily see which index the fund tracks and understand its investment objective.
Suitable for SIP and lumpsumYou can invest regularly through SIP or make a one-time lumpsum investment.
Easy accessibilityOn the Bajaj Broking website, SIP investments start from Rs. 100, subject to scheme availability.

Remember that index funds aim to match the performance of the benchmark index. Their returns will generally move in line with the market after accounting for fund expenses.

What are the risks associated with index funds?

Although index funds are passive investments, they are not risk-free. Their value rises and falls with the market because they closely track a benchmark index.

Understanding these risks can help you make better investment decisions.

RiskWhat it means
Market riskIf the benchmark index falls, the value of your investment may also decline.
Tracking errorThe fund's return may differ slightly from the benchmark due to expenses and operational factors.
Concentration riskSome indices allocate higher weights to a few large companies, making performance dependent on them.
Sector riskSectoral and thematic index funds depend heavily on the performance of a particular industry or theme.
International market riskGlobal index funds are affected by overseas market movements and currency fluctuations.
Interest rate riskDebt index funds may be affected when interest rates change.

Index funds do not protect you from market volatility. Past performance should not be used as a guarantee of future returns.

Who should invest in index funds?

Index funds can suit many investors, but they are not the right choice for everyone. Your investment goals, time horizon and ability to handle market fluctuations should guide your decision.

Index funds may be suitable if you:

  • Want long-term wealth creation. 
  • Prefer a passive investment strategy. 
  • Want exposure to a broad market index. 
  • Plan to invest regularly through SIP. 
  • Are comfortable with market-linked returns. 
  • Want a diversified portfolio without selecting individual stocks. 

They may be less suitable if you:

  • Expect guaranteed returns. 
  • Need your money within a short period. 
  • Cannot tolerate market fluctuations. 
  • Prefer actively managed investment strategies. 

On the Bajaj Broking website, you can choose from 4,000+ mutual fund schemes across equity, debt, hybrid, ELSS and thematic categories after completing your mandatory KYC.

How do you choose an index fund in India?

Choosing an index fund is a straightforward process when you compare the right factors. You can complete the process online on the Bajaj Broking website after completing your KYC.

  1. Define your financial goal and investment horizon before selecting an index fund. 
  2. Choose the benchmark index that matches your objective, such as a broad market, sectoral or international index. 
  3. Compare the fund's tracking error to understand how closely it follows its benchmark. 
  4. Review the expense ratio, which is deducted from the NAV by the AMC and affects overall returns. 
  5. Check the SEBI riskometer to understand the scheme's risk level before investing. 
  6. Complete your KYC, as it is mandatory under SEBI regulations before investing in any mutual fund. 
  7. Invest through SIP or lumpsum. On the Bajaj Broking website, SIP investments start from Rs. 100 per month for eligible schemes.

Frequently asked questions

Do I need a Demat account to invest in index funds?

No. You do not need a Demat account to invest in index mutual funds. You can invest directly in index fund schemes using your PAN, bank account and completed KYC. On the Bajaj Broking website, you can invest in eligible index funds through SIP or lumpsum after completing the mandatory KYC process required under SEBI regulations.

Are index funds a safe investment option?

Index funds are generally considered a simple investment option because they track a benchmark index instead of relying on active stock selection. However, they are not risk-free. Their value changes with market movements, and returns are not guaranteed. Before investing, check the SEBI-mandated riskometer, which ranges from Low to Very High, to understand the scheme's risk level.

What is the difference between an index fund and an ETF?

Both index funds and Exchange Traded Funds (ETFs) track a benchmark index. However, an index fund is bought and redeemed through the mutual fund at the day's applicable NAV, while an ETF is bought and sold on a stock exchange during market hours like a listed security. ETFs generally require a Demat and trading account, whereas index mutual funds do not. The Bajaj Broking website allows you to invest in index mutual funds through SIP or lumpsum.
