What are ETFs and how do they work in real life
Exchange Traded Funds, often called ETFs, have become one of the most talked about investment options in recent years. They are widely used by individual investors, workplace pension schemes and professional fund managers alike.
If you have come across ETFs and wondered what they actually are and how they work, this blog explains the basics in a clear and simple way.

What is an ETF?

An ETF is a type of investment fund that is traded on a stock exchange, much like a company share. Instead of investing in one single company, an ETF usually holds a collection of investments within one fund.
These can include shares, bonds, commodities or a mix of different assets. Many ETFs are designed to track the performance of a specific market index, such as the UK stock market or global equities.
When you invest in an ETF, you are buying a small piece of everything inside that fund rather than betting on one company alone.

How ETFs work in practice ?

ETFs are created by fund providers who build a portfolio that mirrors a chosen index or theme. The fund is then listed on a stock exchange, allowing investors to buy and sell units throughout the trading day.
The price of an ETF moves up and down in line with the value of the underlying investments. This means its value can change frequently, just like shares.
Unlike some traditional funds that are priced once per day, ETFs can be traded whenever markets are open.

What do ETFs invest in?

ETFs can cover a wide range of markets and strategies. Some common examples include:
  • UK or global shares
  • Government or corporate bonds
  • Specific sectors such as technology or healthcare
  • Ethical or sustainability focused investments
  • Commodities such as gold
This variety allows investors to access markets that might otherwise be difficult or costly to invest in directly.

Why people use ETFs?

One of the main reasons ETFs are popular is diversification. By holding many investments within a single fund, ETFs can help spread risk.
They are also known for being cost efficient. Many ETFs have lower ongoing charges compared to actively managed funds, although costs still apply.
Transparency is another benefit. Most ETFs clearly show what they invest in, making it easier for investors to understand where their money is going.

What are the risks of ETFs?

Like all investments, ETFs carry risk. Their value can fall as well as rise, and you could get back less than you invest.
Market risk is the most common risk. If the market or index an ETF tracks falls, the ETF will usually fall too.
Some ETFs focus on specific sectors or regions, which can increase volatility. Currency movements can also affect returns when investing internationally.
It is important to remember that diversification reduces risk but does not remove it entirely.

ETFs versus other investment funds

ETFs are often compared with traditional mutual funds or unit trusts. While both pool investor money together, there are key differences.
ETFs trade on stock exchanges during market hours, while traditional funds are usually priced once per day. ETFs often follow passive strategies, whereas many traditional funds are actively managed.
Neither option is automatically better. The right choice depends on your goals, time horizon and attitude to risk.

Are ETFs suitable for everyone?

ETFs can be suitable for many types of investors, including beginners, but they are not a one size fits all solution.
Some ETFs are simple and broad, while others are complex and higher risk. Understanding what an ETF invests in and how it fits into your overall financial plan is essential.
For long term goals such as retirement, ETFs are often used as part of a diversified portfolio rather than in isolation.

Things to consider before investing in ETFs

Before investing, it is worth thinking about:
  • Your investment goals and time frame
  • Your comfort with market ups and downs
  • Costs including platform fees and fund charges
  • How the ETF fits with your existing investments
Taking time to understand these factors can help you make more confident decisions.

Final thoughts

ETFs offer a flexible and accessible way to invest across a wide range of markets. Their simplicity, transparency and cost efficiency have made them a popular choice for many investors.
However, they are still investments and come with risk. Understanding how they work is an important first step before deciding whether they are right for you.

Alternative investments often engage in leverage and other investment practices that are extremely speculative and involve a high degree of risk. Such practices may increase the volatility of performance and the risk of investment loss, including the loss of the entire amount that is invested. These investments are usually highly illiquid and generally not transferable without the content of the sponsor.

Investing in cryptocurrency is highly speculative and involves significant risk to capital, as its value is extremely volatile and can fluctuate widely in short periods. It is not regulated by the Financial Conduct Authority, meaning investors may not have access to financial protections, including the Financial Services Compensation Scheme (FSCS) or the Financial Ombudsman Service. There is also a risk of loss from fraud, cybersecurity breaches, or operational failures within cryptocurrency platforms. Investors should carefully consider whether they can afford to lose the entirety of their investment.
