How Exchange-Traded Funds Work and What Indian Investors Should Know
By The Worldonomics Times
For investors entering the US stock market, selecting individual companies can sometimes feel overwhelming. There are thousands of listed stocks across technology, healthcare, finance, energy, consumer goods and other sectors.
One investment vehicle that can simplify this process is the Exchange-Traded Fund, or ETF.
ETFs allow investors to gain exposure to a basket of securities through a single investment. They have become an important part of modern investing because they can offer diversification, flexibility and relatively low costs.
For Indian investors exploring US markets, understanding ETFs is an important step toward building a diversified international portfolio.
What Is an ETF?
An Exchange-Traded Fund (ETF) is an investment fund that holds a collection of securities such as stocks, bonds or other assets.
Instead of buying shares of several individual companies, an investor can purchase units of an ETF that provides exposure to a group of securities.
For example, an ETF could be designed to track:
- A broad US stock-market index
- Technology companies
- Healthcare companies
- Dividend-paying companies
- Government bonds
- Specific investment themes
- International markets
The investor owns units of the ETF, while the ETF itself owns the underlying securities according to its investment strategy.
How Does an ETF Work?
ETFs trade on stock exchanges, much like individual stocks.
During market hours, investors can generally buy and sell ETF units at market prices.
The value of the securities held by the ETF determines its Net Asset Value (NAV). The market price of an ETF can move slightly above or below its NAV because of supply, demand and market conditions.
ETF providers use mechanisms involving creation and redemption of fund units to help keep the market price reasonably close to the underlying value of the portfolio.
This structure combines characteristics of both traditional investment funds and exchange-traded securities.
Major Types of US ETFs
There are many types of ETFs available to investors.
1. Broad-Market ETFs
These provide exposure to a large portion of the US equity market.
They can be useful for investors seeking diversified exposure rather than selecting individual companies.
2. Index ETFs
These are designed to track a particular market index.
For example, an index ETF may track a broad-market benchmark or a specific segment of the market.
3. Sector ETFs
These focus on particular industries such as:
- Technology
- Healthcare
- Financial services
- Energy
- Consumer sectors
Sector ETFs allow investors to take a focused position in an industry without selecting individual companies.
4. Bond ETFs
Bond ETFs invest in fixed-income securities such as government or corporate bonds.
They may be used for income generation, diversification or portfolio stability.
5. Dividend ETFs
These focus on companies with dividend-paying characteristics.
Investors interested in income-oriented strategies may consider this category.
6. Thematic ETFs
Thematic ETFs focus on specific trends or themes such as artificial intelligence, clean energy, cybersecurity or other emerging industries.
However, thematic funds can sometimes be more concentrated and volatile.
7. Leveraged and Inverse ETFs
These are more complex products designed to amplify or reverse the daily performance of an underlying benchmark.
They are generally not suitable as simple long-term investments for beginners and require a strong understanding of their structure and risks.
Why Do Investors Use ETFs?
ETFs offer several potential advantages.
Diversification
Instead of depending on one company, an ETF can provide exposure to dozens or even hundreds of securities.
If one company performs poorly, its impact may be smaller when it represents only a portion of the overall portfolio.
Convenience
Buying one ETF can provide exposure to an entire market segment.
This can simplify portfolio construction.
Potentially Lower Costs
Many index-based ETFs operate with relatively low expense ratios because they follow rules-based strategies rather than relying heavily on active security selection.
However, investors should always compare actual costs before investing.
Flexibility
Because ETFs trade on exchanges, investors can generally buy or sell them during market hours.
Transparency
Many ETFs disclose their holdings regularly, allowing investors to understand what assets the fund owns.
ETF vs Individual Stocks
| Feature | ETF | Individual Stock |
|---|---|---|
| Diversification | Usually higher | Depends on company |
| Company-specific risk | Lower | Higher |
| Research requirement | Focus on fund | Extensive company research |
| Trading | Exchange-traded | Exchange-traded |
| Potential return | Depends on underlying basket | Depends on individual company |
| Volatility | Varies | Can be significantly higher |
| Suitable for beginners | Often easier to diversify | Requires more research |
An ETF does not eliminate investment risk. Its performance depends on the assets it holds.
Important ETF Terms
Indian investors should understand several basic terms before purchasing a US ETF.
Expense Ratio
The expense ratio represents the annual operating expenses charged by the fund as a percentage of assets.
For example, suppose an ETF has an expense ratio of 0.10% and an investor has $10,000 invested.
Ignoring other effects, the annual fund expense would be approximately:
$10,000 × 0.10% = $10
Even small differences in costs can become meaningful over long investment periods.
NAV
NAV represents the value of the ETF’s underlying assets after accounting for liabilities, generally expressed per unit.
Bid-Ask Spread
The difference between the price at which investors can buy and sell an ETF.
Highly liquid ETFs generally tend to have narrower spreads, although this varies by fund and market conditions.
Assets Under Management
AUM indicates the amount of money managed by the ETF.
It can provide useful information about the fund’s scale, although larger AUM does not automatically mean better investment performance.
Tracking Difference
An index ETF may not perfectly match the return of the index it follows.
Expenses, transaction costs, taxes and other factors can create differences between the ETF’s performance and its benchmark.
How Should Beginners Evaluate an ETF?
Before investing, investors should consider:
- What does the ETF invest in?
- Which index or strategy does it follow?
- What are its major holdings?
- What is the expense ratio?
- How liquid is the ETF?
- How closely has it tracked its benchmark?
- Is the portfolio too concentrated in a particular company or sector?
- Does the investment objective match your financial goals?
The name of an ETF should never be the only reason to invest.
An attractive theme can still represent an expensive or highly concentrated investment.
ETFs vs Mutual Funds
ETFs and mutual funds both pool investors’ money into portfolios of securities, but they operate differently.
| ETF | Mutual Fund |
|---|---|
| Trades on an exchange | Usually bought/redeemed through fund structure |
| Market price changes during trading hours | Transactions generally based on NAV |
| Often suitable for exchange-based trading | Traditionally designed for fund-based investing |
| Can have relatively low costs | Costs vary widely |
| Wide range of passive and active strategies | Wide range of active and passive strategies |
The exact tax and regulatory treatment can differ significantly by country and investor status.
What Should Indian Investors Consider?
For an Indian investor buying US-listed ETFs, diversification does not remove currency risk.
Suppose an investment rises in US dollar terms, but the dollar weakens significantly against the Indian rupee. The return measured in rupees could be lower.
Conversely, currency movements can also increase rupee-denominated returns.
Indian investors should also understand:
- Brokerage and transaction charges
- Currency conversion costs
- US withholding taxes where applicable
- Indian tax treatment
- Reporting requirements
- Regulations applicable to overseas investments
- ETF domicile and structure
Tax rules can change, so investors should verify the current rules applicable to their individual circumstances before investing.
A Simple Beginner’s Framework
A practical approach can be:
Step 1: Define your investment objective.
Step 2: Decide whether you need broad-market, sector, bond or thematic exposure.
Step 3: Examine the ETF’s holdings.
Step 4: Compare expense ratios and tracking performance.
Step 5: Check liquidity and bid-ask spreads.
Step 6: Understand currency and tax implications.
Step 7: Consider how the ETF fits into your overall portfolio.
This process can help investors avoid selecting an ETF simply because it has recently performed well.
Conclusion
ETFs have transformed the way investors access financial markets. A single ETF can provide exposure to a diversified collection of stocks or bonds, making ETFs an attractive tool for investors who want a simpler approach to portfolio construction.
For Indian investors exploring the US market, ETFs can provide access to broad market segments without requiring the investor to research every individual company.
However, ETF does not automatically mean low risk. Investors must understand what the fund owns, its costs, concentration, strategy, liquidity, currency exposure and tax implications.
The most important principle is simple:
Do not invest in an ETF merely because it is popular. Understand what is inside it and why it belongs in your portfolio.
