Exchange-traded Funds (ETFs) require little effort to manage, are generally considered cost-efficient and accessible,, and come with relatively low fees. These are the main reasons why ETFs are popular among investors who are both risk-averse and those seeking diversified market exposure. However, ETFs are subject to market risk and may fluctuate in value. This is also why the ETF industry globally reached US$19.44 trillion in November 2025.

If you are a newcomer, the one thing you must know is that there are different types of ETFs that you can invest in, and all of them offer different benefits and risks. In this blog, we will understand the different ETF categories of investing in equity markets.

What are ETFs and How Do They Work?

An exchange-traded fund, or ETF, is an investment product that contains a portfolio of assets, including stocks, bonds or commodities, and trades on a stock exchange just like stocks. Just one ETF allows you to invest in different stocks and market segments instead of purchasing each individually. You can buy and sell them during market hours, just as with individual stocks. The value of an ETF may go up or down depending on market conditions and the performance of its underlying assets.

When you purchase one stock, you are investing in the performance of one company. An ETF, on the other hand, diversifies your investment among several securities simultaneously, which is useful in reducing the effect of any single holding on the overall performance. This diversification is among the factors that make ETFs commonly used as portfolio building blocks, not as a standalone bet.

Different Types of ETFs

In a dynamic and volatile market, ETFs are generally considered diversified investment instruments that are easy, adaptable and effective. The level of risk varies depending on the ETF structure, asset class, and market exposure. There are, however, different types of ETFs that have varying benefits and risk-return profiles. Here are the types of ETF categories you can invest in based on your risk-return profile:

• Equity ETFs
• Bond ETFs
• Sector ETFs
• Thematic ETFs

1. Equity ETFs: Wide Stock Market Exposure

Equity ETFs are investment funds that mostly contain a portfolio of stocks. It offers investors exposure to an entire portfolio of stocks with a single ETF instead of purchasing shares of individual companies. It follows stock indices or pre-determined portfolios and reflects the performance of a larger market segment as opposed to the performance of a single company.

There are again different types of equity ETFs that help meet different investment objectives, risk-taking and market expectations. Before investing in equity ETFs, you must understand these different types of equity ETFs:

A. Broad-Market ETFs

These ETFs track the large stock indexes or the whole market segment. These include ETFs tracking global indices or total stock market indices. It provides an investor with significant exposure to a variety of companies. It is ideal for investors who want to follow the general market performance without focusing on a particular sector or style. Returns are linked to overall market movements and may be affected by periods of market downturn.

B. Style-Based ETFs

Style-based ETFs are based on a particular investment strategy, e.g. growth, value or a combination strategy. Style-based ETFs allow investors to identify a specific market philosophy or strategy and invest following it.

• Growth ETFs: These are funds that invest in companies that are likely to grow at a faster rate than the market and may be subject to higher price volatility.
• Value ETFs: Value ETFs are funds that invest in stocks that are undervalued on the basis of fundamentals and may take time to realise potential value.

C. Market-Cap-Based ETFs

These ETFs target companies of a given size. Large-cap ETFs track more established and stable companies, whereas mid-cap and small-cap ETFs track smaller companies that have a higher growth potential but are riskier. It assists investors in customising their portfolios according to the exposure to company size and risk tolerance.

D. Sector ETFs (Equity-Focused)

Some equity ETFs, though discussed in a different section, are sector funds, such as technology, healthcare, or finance. They can be used by investors to overweight or diversify exposure in specific market sectors. Concentration in a single sector may increase volatility and risk.

E. Dividend and Income-Oriented ETFs

There are equity ETFs that are specifically oriented towards dividend-paying companies, offering a combination of growth and income. These ETFs are ideal for investors who want to have a steady cash flow and engage in equity markets. Dividend payments are not guaranteed and may change over time.

Equity ETFs are favoured due to diversification, reduced charges, and the convenience of investing in equity. Although ETFs make it easier to invest in the stock market, equity ETFs are associated with risks such as market volatility and tracking errors. This is why you must choose a type of equity ETF based on your investment objectives, diversification, and risk profile.

2. Bond ETFs: An Alternative to Fixed-income Investing

Bond ETFs are funds that invest in a portfolio of fixed-income securities, including government bonds, corporate bonds, or municipal bonds. It exposes investors to a diversified basket with one ETF instead of purchasing individual bonds. It allows easy entry into the bond market and offers an easy method of adding fixed-income assets to a portfolio.

Why Investors Invest in Bond ETFs?

Here are the key benefits of bond ETFs that make them popular among different sets of investors:

• Income potential: Bond ETFs pay regular interest on the underlying securities. Income levels may vary depending on interest rate movements and issuer credit quality.
• Portfolio stability: Fixed-income exposure can decrease the overall portfolio volatility and offer balance to equity investments.
• Ease of investing in bond markets: Bond ETFs allow you to easily access a wide variety of bonds without having to buy them separately, which can be complicated and expensive.

Although bond ETFs are convenient and diversified, they might react to interest rate sensitivity and the overall performance of the ETF. Bond ETFs provide a versatile means of adding fixed-income assets to a portfolio, yet they have complex mechanics and risks that need to be understood to make informed investment choices.

3. Sector ETFs: Industry Focus

Sector ETFs are specialised funds that target a particular industry or economic sector, like technology, healthcare, finance, or energy. These ETFs offer a focused exposure to companies in one sector as opposed to investing in the entire stock market. This allows investors to make their portfolio match their perception of industries that have a high growth potential or strategic significance.

Why Investors Invest in Sector ETFs?

Here are all the benefits of sector ETFs that make them popular among investors:

• Targeted Industry Exposure: Sector ETFs allow investors to focus on a specific industry with strong growth potential without selecting individual stocks.
• Diversification within a sector: You can diversify your portfolio within a sector instead of relying on the performance of one company.
• Low-cost and Efficient: It is more cost-efficient than buying multiple individual stocks to gain the same industry exposure.

Sector ETFs provide a more specific exposure, but are riskier than more general market ETFs. Investing in a single industry exposes the company to industry-specific risks. Sector performance may also vary more significantly than the market as a whole because of economic changes, regulatory changes, or market sentiment.

4. Thematic ETFs: Investing in Big Ideas, Long-term Trends

Thematic ETFs are funds that are built on long-term trends or broad concepts as opposed to the traditional sectors or indices. Thematic ETFs may also be based on innovations or societal changes, unlike sector ETFs, which track a particular industry. It offers you an opportunity to match your portfolios to new trends and changing markets in one convenient investment.

Why Investors Invest in Thematic ETFs?

Here are all the benefits of thematic ETFs that make them popular among investors:

• Long-term Exposure: Thematic ETFs are famous due to their exposure to long-term themes that might influence the future economy.
• Innovation-based Strategy: It lets you engage in innovation-based strategies without necessarily selecting companies.

This makes it ideal for investors who are seeking to introduce a forward-looking or growth-oriented component to their portfolios. Although thematic ETFs may be thrilling, the ETF can perform poorly in case the theme does not pick up. New or niche trends may also vary significantly in price and may be subject to higher volatility and lower liquidity.
