What are Passive Mutual Funds? A Complete Beginner's Guide

Passive mutual funds have become a significant part of India's growing investment landscape, encompassing index funds, exchange-traded funds (ETFs), gold ETFs and overseas fund-of-funds. Unlike actively managed funds, passive funds generally aim to replicate the performance of a specific market index rather than selecting securities with the objective of outperforming it. This approach may offer a relatively simple way to invest in a diversified market segment through a single mutual fund.

Meaning of Passive Mutual Funds: The Simple Explanation

A passive mutual fund is a fund designed to replicate or track a specified market index or benchmark. Its portfolio generally seeks to hold the securities and weights represented by the underlying index, subject to the scheme’s investment strategy and permitted deviations.

For example, an index fund tracking the Nifty 50 aims to hold the constituent stocks of the Nifty 50 in proportions that closely reflect the index. As the index changes, the fund's portfolio is adjusted accordingly.

AMFI classifies index funds and ETFs as passive funds because their portfolios seek to replicate a stated index or benchmark. The fund manager's role is primarily to maintain the portfolio in line with the benchmark while keeping tracking error under control.

The objective is therefore not to identify individual stocks that may outperform the market. Instead, the fund seeks to provide returns that broadly correspond to the performance of its chosen benchmark, before expenses and other tracking differences.

Now that you know the passive fund meaning, let’s see how index linked investing works.

How Index-Linked Investing Actually Works

Passive investing follows a relatively structured process:

1. An index is selected

The fund first identifies a benchmark it intends to track, such as the Nifty 50, Nifty Next 50 or another recognised index.

2. The portfolio is constructed

The fund purchases securities that form part of the selected index. The holdings are generally maintained in proportions that reflect the index methodology.

3. The index changes

When the index changes, the fund updates its portfolio. This may not happen immediately because of transaction timing, liquidity, and corporate actions.

4. Tracking is maintained

The fund attempts to keep its performance close to that of the benchmark. Expenses, transaction costs, cash holdings and other factors can create a difference between the fund's performance and the index.

This difference between a passive fund's return and the return of its benchmark over a period is commonly referred to as tracking difference. Tracking error measures the volatility of this return difference over time. A lower tracking error generally indicates more consistent tracking, while a lower tracking difference indicates that the fund's return has remained closer to the benchmark over the relevant period.

Types of Passive Funds Available in India

Passive funds cover several investment categories. Some of the common types are:

Type of Passive Fund What It Tracks or Represents How It Works
Index Funds Market indices such as Nifty 50 Replicates the selected index
Equity ETFs Equity indices or specific market segments Trades on stock exchanges like shares
Gold ETFs Domestic gold prices Provides exposure to gold through an exchange-traded structure
Silver ETFs Silver prices Tracks the underlying silver-related benchmark or asset exposure
International Index Funds Overseas indices or markets Provides exposure to selected international markets
Overseas Fund of Funds International funds or securities Invests in underlying overseas funds

The structure, liquidity, costs and taxation can differ across these categories. Investors therefore need to examine the specific scheme before investing.

The Real Advantages of Choosing Passive Over Active

Passive investments come with some characteristics that make them suitable for investors who are interested in a systematic index investment.

  • Diversification: A single index investment may provide you with access to many securities in one go.
  • Investment methodology: Investments made in such funds will be based on the index itself.
  • Portfolio turnover: Because a passive index fund does not change frequently, there will be no frequent buying and selling.
  • Expense ratio: Expense ratios in the case of passive investment funds are relatively low since there is no active picking of securities in the portfolio.
  • Transparency: The underlying benchmark and its methodology are generally disclosed, making the investment strategy easier to understand and monitor.
  • Ease of investing: As an investor, you do not need to analyse stocks within the index.

However, these features do not mean passive funds will always perform better than active funds. Their performance remains linked to the underlying index and market conditions.

Limitations and Risks You Should Know Before Investing

Passive investments also carry some limitations that you need to take into account when choosing your fund.

  • Tracking error: Passive funds may not track the exact performance of the index in question due to expenses, transaction costs, cash holdings and other reasons.
  • Market risk: If the index falls in value, the passive fund will fall too.
  • Flexibility limitation: A fund tracking an index generally cannot substantially change its holdings only because the fund manager expects a particular company or sector to underperform.
  • Concentration risk: Some indexes may be heavily weighted toward specific sectors or stocks. Just because the index is diversified does not necessarily mean that it is diversified across every part of the economy.
  • Trading liquidity difference: Exchange-traded funds trade on exchanges; thus, their trading liquidity may differ. Index mutual funds do not trade as stocks but as mutual funds do.

Who is Best Suited for Passive Fund Investing?

Passive funds may be considered by:

  • Beginners looking for diversified market exposure
  • Investors who prefer index-linked investing
  • Individuals seeking a relatively simple long-term portfolio approach
  • Investors who do not want to analyse individual stocks regularly
  • Investors building a diversified allocation across different asset classes
  • Investors who prefer investing periodically through SIPs in eligible index mutual funds.

The suitability of a passive fund depends on the investor's financial goals, time horizon, risk tolerance and the specific index being tracked.

How to Start Investing in Index Funds: A Step-by-Step Guide

Investing in an index fund generally involves a few basic steps.

Step 1: Identify the investment objective

Determine why you are investing and the period for which you expect to remain invested.

Step 2: Choose an appropriate index

Understand whether you want exposure to a broad market index, a specific sector, market segment or another asset class.

Step 3. Compare Relevant Funds

If multiple funds track the same index, compare their expense ratios, tracking error, tracking difference, fund size, portfolio and other relevant scheme details.

Step 4. Check the Scheme Documents

Read the scheme information, investment objective, riskometer, costs, exit load and other applicable terms before investing.

Step 5. Choose the Investment Route

Index funds can generally be accessed through the mutual fund investment route. Investors can also consider whether SIP or lump sum investing fits their circumstances.

Step 6. Review Periodically

Passive investing does not require frequent portfolio decisions, but investors can still review whether the fund, index and investment continue to match their financial objectives.

Tax Treatment of Passive Mutual Fund Returns in India

Taxation of passive funds depends largely on the type of underlying investment and the structure of the scheme. A passive equity index fund and a passive debt-oriented fund, for example, may not receive identical tax treatment.

For equity-oriented mutual funds, capital gains are generally classified as short-term or long-term based on the applicable holding period. The applicable tax rates and exemptions depend on prevailing tax rules.

Other passive funds can be subject to different tax treatment. Therefore, investors should check the scheme's classification and the latest Income Tax rules before calculating the post-tax return.

Tax should also be considered alongside the fund's expenses and investment horizon. The return shown by a fund before taxes does not necessarily represent the amount an investor will retain after applicable taxes and charges.

Conclusion

Passive mutual funds provide a structured way to invest in a market index or other defined benchmark without relying on frequent security selection by a fund manager. Their relatively simple strategy, diversification and index-linked approach can make them useful for investors with different investment objectives and time horizons. However, passive investing still carries market risk, tracking differences and other limitations that need to be understood before investing.

Frequently Asked Questions on Passive Fund Investing


Are passive mutual funds better than active mutual funds?

Who should invest in passive mutual funds?

Passive funds may suit investors seeking simple, index-based market exposure, relatively lower costs and limited dependence on active fund management decisions.

How are passive mutual funds taxed in India?

Tax treatment depends on the fund's underlying assets and classification. Equity-oriented and non-equity passive funds can have different applicable tax rules.

Which fund is better, active or passive?

The choice depends on investment goals, costs, risk tolerance and preference for index tracking or active portfolio management and decision-making.

What is an example of a passive investment?

A Nifty 50 index fund is an example because it aims to replicate the composition and performance of the Nifty 50 Index.
