What Is an ETF?

An ETF, or Exchange-Traded Fund, is a pooled investment vehicle traded on stock exchanges. When we define ETF, it means a fund that can hold various assets like stocks, bonds, or commodities. This lets investors buy shares like they would a regular stock.

With ETFs, diversification and ease of trading go hand in hand. If you’ve wondered “whats an eft,” or want an accurate ETF definition, think of a single fund sharing similar features with both stocks and mutual funds.

How Do ETFs Work? Understanding the Basics

ETFs work by pooling money from many investors to buy a basket of assets. Each ETF aims to track a specific benchmark, such as the S&P 500 or FTSE 100, offering easy access to broad markets.

ETFs are quoted on stock exchanges, so you can buy or sell them just like company stocks throughout the trading day. This makes them accessible and flexible compared to some other funds.

Authorised participants keep ETF prices in line with the value of underlying assets via a “creation and redemption” process. They add or remove assets from the ETF as demand fluctuates.

Key Features and Benefits of ETFs

Diversification and risk management

ETFs provide investors with instant diversification by pooling a range of assets within a single fund, such as stocks, bonds, or commodities. By including just one ETF in your portfolio, you reduce exposure to individual company risk and spread your investments across an entire market or sector. This approach supports better portfolio risk management and smoother returns over time.

Liquidity and flexibility

One major advantage of ETFs is their liquidity. As they trade on stock exchanges, ETFs can be bought or sold throughout the trading day at real-time market prices. This gives investors greater flexibility than mutual funds, which can only be traded at the end of the trading day. You can respond to market movements swiftly, take advantage of opportunities, or adjust your portfolio on demand, enhancing overall investment control.

Cost-effectiveness

ETFs are known for their cost-effectiveness. Most are passively managed, tracking a specific index, which helps maintain lower management fees compared to actively managed funds. The savings on costs mean more of your money remains invested, supporting stronger long-term returns. In addition, ETFs typically have lower transaction costs due to efficient structures and straightforward trading.

Transparency and accessibility

Transparency is a hallmark of ETFs. Most funds publicly disclose their holdings daily, allowing investors to see exactly what assets their money is exposed to. This clarity builds trust and makes it easier to track your investment’s performance. ETFs are also highly accessible, available on major exchanges and easily added to individual portfolios, enabling investors of all experience levels to participate.

Popular Types of ETFs

There are several varieties of ETFs:

  • Equity (stock) ETFs: Track groups of company shares
  • Bond ETFs: Track government or corporate debt instruments
  • Commodity ETFs: Hold assets like gold or oil
  • Currency ETFs: Track foreign exchange rates
  • Sector and thematic ETFs: Focus on specific industries or trends
  • Crypto ETFs: Track digital assets like Bitcoin or Ethereum

Passive ETFs mirror an index, while active ETFs have managers picking investments. Passive ETFs aim to replicate the performance of an index by automatically tracking its underlying assets. They are cost-effective and transparent. Active ETFs, by contrast, have professional managers selecting securities with the goal to outperform a benchmark, offering potential for higher returns but often at a higher cost.

Equity (Stock) ETFs

Equity ETFs are designed to track the performance of a group of company shares. They offer exposure to broad markets, like the S&P 500, or specific regions and sectors. Equity ETFs allow investors to diversify across many companies with just a single investment, reducing the risk linked to holding individual stocks.

Bond ETFs

Bond ETFs invest in various fixed-income instruments, such as government, municipal, or corporate bonds. They provide a convenient way to access income-producing assets and manage portfolio risk. Bond ETFs enable investors to diversify their holdings while benefitting from regular interest payments and potential capital stability.

Commodity ETFs

Commodity ETFs give investors access to physical assets like gold, silver, oil, or agricultural products. Instead of buying the commodity itself, you can invest through an ETF, which is simpler and more cost-effective. These funds help hedge against inflation and diversify portfolios with assets less correlated to stocks and bonds.

Currency ETFs

Currency ETFs track the value of foreign currencies against the British Pound, US Dollar, or other benchmarks. These funds allow investors to gain exposure to changes in exchange rates without directly trading on the forex market. Currency ETFs can be useful for hedging international investments or speculating on currency movements.

Sector and Thematic ETFs

Sector ETFs focus on specific industries like technology, healthcare, or energy, while thematic ETFs target long-term trends such as clean energy or artificial intelligence. These ETFs enable investors to concentrate their portfolio on particular market segments, providing a strategy to benefit from sectoral or thematic growth opportunities.

Crypto ETFs

Crypto ETFs provide exposure to digital assets like Bitcoin or Ethereum without the need to hold or manage cryptocurrencies directly. These funds track the price of underlying crypto assets, offering an accessible route into the digital asset market. Crypto ETFs simplify access, provide institutional-grade security, and make portfolio diversification more efficient.

ETFs vs. Mutual Funds vs. Stocks: Key Differences

ETFs, mutual funds, and stocks each serve different purposes and suit investors in different ways. Understanding the distinctions is crucial when building a strong portfolio.

ETFs trade on stock exchanges throughout the day, just like shares, giving you flexibility to buy or sell any time markets are open. Mutual funds, by contrast, are only traded once per day after the market closes, at a price based on the fund’s net asset value. This timing can limit immediate access and flexibility.

Costs are another key difference. ETFs generally come with lower management fees and operating costs compared to mutual funds, especially when passively managed. While ETFs may carry transaction or brokerage fees, their overall cost structure is typically more competitive.

Mutual funds often impose minimum investment amounts and potentially higher annual fees due to active management. In contrast, ETFs have no such entry barriers, making them highly accessible.

Stocks represent direct ownership in a single company and carry higher individual company risk. An ETF, however, pools together many assets, providing instant diversification. This can reduce the impact of any single company’s poor performance and help manage overall portfolio risk.

When it comes to tax efficiency, ETFs can offer advantages thanks to their unique creation and redemption process, minimising capital gains distributions compared to many mutual funds. Stock trading can also be tax-efficient, but diversification is limited by individual positions.

Table suggestion: Compare ETFs, mutual funds, and stocks on cost, flexibility, diversification, minimum investment, tax treatment, and trading method.

What Is a Crypto ETF? (Including Bitcoin ETFs)

A crypto ETF is a type of exchange-traded fund that tracks the price of cryptocurrencies. Crypto ETFs let investors gain exposure to digital assets like Bitcoin or Ethereum without directly owning the underlying coins.

These funds trade like traditional ETFs but track crypto markets. Spot crypto ETFs hold the actual cryptocurrency, while futures-based crypto ETFs use derivatives. Bitcoin ETFs and Ether ETFs are the most prominent examples.

Recent approvals by the SEC in the US for spot Bitcoin and Ethereum ETFs marked a milestone. In many countries, like the UK, crypto ETF offerings remain limited due to regulatory restrictions, though global interest is rising.

Opting for a crypto ETF means avoiding the hassle of wallet management, private keys, or direct exchange risk. However, pricing may not perfectly match the crypto market due to management and structure.

Pros and Cons of ETFs and Crypto ETFs

Advantages

ETFs offer instant diversification, transparency, trading flexibility, and lower fees. Crypto ETFs provide exposure to digital assets without security risks or complicated setups, fitting easily within traditional broker platforms.

Disadvantages/risks

Market volatility still exists, and ETFs can be subject to tracking errors. Crypto ETFs face regulatory uncertainty and potential liquidity issues. Investors may not capture all the benefits of direct crypto holdings, such as use within decentralised finance.

How to Start Investing in ETFs and Crypto ETFs

To get started, open a brokerage account or investment platform registered in your region, like the UK. For tax-efficient investing, consider ISAs or SIPPs for eligible ETFs. Research the fund’s holdings, costs, and performance before purchasing shares.

For crypto ETFs, check market availability. Do also assess platform fees and regulatory status before investing.
