Passive Mutual Funds: Meaning, Types, Benefits & How They Work
What if you could invest in the stock market without worrying about selecting individual stocks? That’s the idea behind passive mutual funds. They follow a market index, making investing simpler, transparent, and often more affordable for long-term investors.
In this blog, learn the basics of passive mutual funds and their working.
What are Passive Mutual Funds?
Passive mutual funds are the schemes designed to replicate the performance of a market index instead of trying to outperform it.
Rather than relying on a fund manager to select stocks, these funds automatically invest in the same companies that make up the underlying index and in nearly the same proportion.
For example, if a passive mutual fund tracks the Nifty 50 Index, it invests in the same 50 companies included in the index. When the index changes, the fund updates its portfolio accordingly.
What is Passive Investing?
Passive investing is a long-term investment strategy where investors aim to mirror the performance of a market index instead of trying to beat it.
Unlike active investing, where fund managers regularly buy and sell securities based on research and market predictions, passive investing follows predefined rules. The portfolio changes only when the underlying index changes.
This approach focuses on:
- Matching overall market returns
- Reducing unnecessary trading
- Keeping investment costs low
- Building wealth over the long term
Because there is less buying and selling, passive investing also tends to have lower management costs than actively managed funds.
How Do Passive Mutual Funds Work?
Passive mutual funds follow a simple investment process.
1. The fund selects a benchmark index
Every passive mutual fund is linked to a specific market index, such as the Nifty 50, Sensex, or Nifty Next 50.
2. The fund purchases the same securities
The fund invests in the companies included in the chosen index.
For example, if Reliance Industries accounts for 10% of the Nifty 50, the fund allocates approximately the same percentage of its portfolio to Reliance.
3. Investments remain aligned with the index
The fund manager does not actively pick stocks or predict market movements. Instead, the portfolio simply mirrors the benchmark.
4. The portfolio is rebalanced
Whenever the index provider adds or removes companies, the fund automatically adjusts its holdings to continue tracking the index.
As a result, investors receive returns that closely resemble the performance of the selected benchmark, subject to a small difference known as the tracking error.
Types of Passive Mutual Funds in India
Passive mutual funds in India mainly come in two forms:
- Index Funds: Bought and sold directly through the mutual fund company at the day’s Net Asset Value (NAV).
- Exchange Traded Funds (ETFs): Bought and sold on stock exchanges like shares during market hours. You need a demat and trading account to invest in them.
Based on what they invest in, passive mutual funds can be divided into the following types:
| Type of Passive Mutual Fund | What It Tracks | Examples |
| Large Cap Index Funds | India’s largest companies | Nifty 50, Sensex, Nifty Next 50 |
| Mid Cap & Small Cap Index Funds | Mid-sized and small companies | Nifty Midcap 150, Nifty Smallcap 250, Nifty 500 |
| Smart Beta (Factor-Based) Funds | Stocks selected using specific investment strategies | Momentum Funds, Low Volatility Funds, Equal Weight Funds |
| Sectoral & Thematic Funds | A particular industry or sector | Banking, IT, Healthcare, Auto, Defence, Energy |
| International Index Funds | Overseas stock markets | S&P 500, Nasdaq 100, Global Index Funds |
| Debt Passive Funds | Government securities and fixed-income indices | Target Maturity Funds (TMFs), G-Sec ETFs |
| Commodity Funds | Commodity prices | Gold ETFs, Gold Funds, Silver ETFs |

What are the Benefits of Passive Mutual Funds?
Passive mutual funds offer several advantages for long-term investors looking for a simple and cost-effective way to invest.
- Lower investment costs
Passive mutual funds track a market index instead of relying on active stock selection. This keeps expense ratios lower than most actively managed funds.
- Diversification
These funds invest across all the companies in an index. This reduces the impact of poor performance by any single stock.
- Transparency
Their holdings closely match the benchmark index. This makes it easy to understand where your money is invested.
- Disciplined investment approach
Passive funds follow predefined investment rules. They avoid frequent buying and selling based on market predictions.
- Suitable for long-term wealth creation
Passive investing encourages staying invested for the long term. This helps investors benefit from overall market growth.
Risks of Investing in Passive Mutual Funds
Passive mutual funds also have certain risks that investors should understand before investing.
- Market risk
These funds move with the market. If the benchmark index falls, the fund’s value is also likely to decline.
- Tracking error
A fund’s returns may differ slightly from its benchmark. This can happen due to expenses, cash holdings, or portfolio rebalancing.
- Cannot outperform the market
Passive funds aim to match the benchmark, not beat it. Their returns generally stay close to the index.
- Concentration risk
Some indices are heavily weighted towards a few companies or sectors. This can increase exposure to those areas.
- Limited flexibility
Passive funds follow a fixed strategy. They cannot quickly adjust their portfolio during market volatility.
Who Should Invest in Passive Mutual Funds?
Passive mutual funds can be suitable for a wide range of investors, particularly those who prefer a simple and disciplined investment strategy.
They may be suitable for:
- Beginners who are new to mutual fund investing.
- Long-term investors aiming to build wealth gradually.
- Investors looking for lower investment costs.
- Individuals who do not have the time or expertise to research and select stocks.
- Investors who want returns that broadly match the overall market.
How to Invest in Passive Mutual Funds
Here are the simple steps that you must follow to start investing in passive funds –
Step 1: Open an investment account
You can invest through a mutual fund app, an Asset Management Company (AMC), or a registered investment platform. If you plan to invest in Exchange-Traded Funds (ETFs), you will also need a demat and trading account.
Step 2: Choose an appropriate benchmark
Select a passive mutual fund that tracks an index aligned with your investment goals and risk tolerance. Broad market indices, such as the Nifty 50 or Sensex, are common choices for long-term investors.
Step 3: Compare different funds
Before investing, compare factors such as the expense ratio, tracking error, assets under management (AUM), and the fund’s historical ability to closely follow its benchmark.
Step 4: Decide your investment method
You can invest through a lump sum or start a Systematic Investment Plan (SIP), which allows you to invest a fixed amount at regular intervals.
Step 5: Stay invested
Passive investing works best over the long term. Instead of reacting to short-term market fluctuations, review your investments periodically and remain focused on your financial goals.
Things to Consider Before Investing in Passive Mutual Funds
Before choosing a passive mutual fund, keep the following factors in mind.
- Expense ratio
Although passive funds generally have lower costs than active funds, comparing expense ratios can help maximise long-term returns.
- Tracking error
A lower tracking error indicates that the fund is more closely replicating the performance of its benchmark index.
- Investment horizon
Passive mutual funds are generally more suitable for long-term investment goals, allowing sufficient time to benefit from market growth.
- Risk tolerance
Although passive funds reduce stock selection risk, they are still exposed to market movements. Ensure the investment aligns with your financial objectives and ability to manage market fluctuations.
- Underlying index
Understand the benchmark the fund tracks. Different indices have varying levels of diversification, sector exposure, and risk.
Conclusion
Passive mutual funds offer a simple and low-cost way to participate in the market without actively selecting stocks. If you’re a long-term investor looking for diversified, market-linked returns, they can be a practical addition to your investment portfolio.
