Passive investing aims to replicate the performance of a chosen benchmark index through a transparent, rules-based portfolio. It is a relatively low-cost investment strategy where you construct a portfolio that mirrors an existing market index (think the Nifty 50 or the BSE Sensex) instead of trying to outperform it.

Let's break down what passive investing is, how it actually functions, and whether you should consider investing in passive funds in India.

What is Passive Investing?

Passive investing means building a portfolio that aims to mirror a market index or commodity, say, the Nifty 50 or gold, instead of trying to outperform it. At the investor level, it involves choosing passive funds like index funds and ETFs that seek to copy an underlying index's constituents and potential returns. Indices, whether broad-market or sectoral, typically follow a clear, rule-based structure, offering transparency into their methodology and holdings.

How Does Passive Investing Work?

1. The index gets built first. A benchmark like the Nifty 50 picks its companies based on fixed methodology based on market cap, liquidity, sector weight etc.

2. A fund is launched to track it. Fund houses roll out passive funds, index funds, ETFs, built specifically to mirror that index.

3. The portfolio aims to replicate the index. The fund manager buys roughly the same stocks in roughly the same proportions.

4. The fund adjusts as the index changes. As the index undergoes periodic reviews, the fund is rebalanced to stay aligned with it .

5. Potential returns close to the benchmark. The fund seeks to generate returns close to those of the benchmark. However, its returns may differ because of the expense ratio, transaction costs, cash holdings, rebalancing costs and other operational factors.

Please note: Tracking difference measures the return gap, while tracking error shows how consistently the fund tracks the benchmark.

What Are the Benefits of Passive Investing?

Relatively Lower Costs: Passive funds usually come with lower expense ratios than actively managed ones as they make fewer tactical portfolio changes. Even a modest annual difference in expenses can materially affect the final value of an investment over a long period.

Diversification: Some indices are built to represent a broad slice of the market while others may represent a specific segment or sector. A broad-market index fund can spread exposure across several companies and sectors. The level of diversification depends on the index being tracked.

Transparency: Passive funds generally offer high transparency because the benchmark methodology and constituents are publicly available.

Rules-Based Investment Approach: At the fund management level, investment is made based on a fixed, published methodology. However, investors must still avoid emotionally driven investment decisions.

What Investment Options Are Available for Passive Investing?

Picking a suitable passive investment strategy depends on your unique risk appetite and objectives:

Index Funds - These are mutual funds that aim to copy a chosen index. You buy and sell them just like any other mutual fund, no demat account needed, which makes them a convenient entry point if you're new to passive investing.

ETFs (Exchange Traded Funds) - These trade on the stock exchange, just like shares do. You'll need a demat and trading account for these. They may be suitable if you are familiar with liquidity, spread and price–NAV considerations, and want the flexibility of buying or selling during market hours.

Gold ETFs – Offer gold exposure without the hassle of storage or purity issues and aim to track the price of physical gold.

Other index-tracking products – Debt index funds, or international index funds and ETFs track global benchmarks like the S&P 500. These offer passive investment options if you're looking to diversify beyond Indian equities.

Passive Investing vs Active Investing

Before deciding where to invest, it helps to know the difference between active and passive investment styles. Here's how passive investing vs active investing stack up side by side.

Parameter	Passive Investing	Active Investing
Investment Objective	Aim to match the benchmark's returns	Try to beat the benchmark
Cost	Relatively lower expense ratio	Higher expense ratio
Role of Fund Manager	Tracks and rebalances with the index	Actively selects securities and makes portfolio decisions
Flexibility	Low, sticks close to the index	High, manager has more flexibility to shift holdings depending on scheme mandate
Diversification	Depends on underlying index being tracked	Depends entirely on the manager and scheme mandate
Investment Approach	Rules-based and mechanical	Discretionary, driven by research

Depending on their risk appetite and objectives, some investors may consider a core passive fund strategy for low-cost market exposure, along with an active fund strategy for tactical satellite allocations.

Who Should Choose Passive Investing?

Beginners - If you're just starting out on your investment journey, passive investing can offer a relatively low-cost and diversified path to investing when a suitable index is chosen.

Long-term investors - The lower costs and potential compounding effect can make a material difference over a long horizon.

Cost-conscious investors - Lower costs can allow a greater proportion of the investment to remain invested.

Investors seeking diversified market exposure - One product offers exposure to a broad basket of companies or specific segments (depending on the underlying index). No active stock-picking skills are required for portfolio construction.

How Can You Invest in Index Funds and ETFs?

Index fund units can be purchased directly through an AMC's website or app, or through a mutual fund distributor or advisor, subject to completion of KYC and the applicable transaction process. It's the same process as any other mutual fund––complete your KYC, then invest via SIP or a lump sum. No demat account needed for this path into passive investing.

ETFs work a bit differently. They trade on the stock exchange like regular shares, so you'll need a demat and trading account, and you'll place buy or sell orders through your broker during market hours.

Passive fund investment can be part of a balanced portfolio, whether you want to keep things simple with index mutual funds, or want the flexibility that comes with exchange-traded products.

Conclusion

Passive investing follows a simple idea: track the market instead of trying to outperform it, and let time allow for potential compounding. It can offer relatively low-cost access to different markets and asset classes depending on the index being tracked. However, before considering index funds and ETFs, investors should evaluate the underlying index, expense ratio, tracking record, and suitability for their goals and risk tolerance. These products remain subject to market risk and tracking difference.
