What is the FTSE 100?

The Financial Times Stock Exchange 100 (FTSE 100 for short, sometimes referred to as the “footsie”) is a stock market index comprising the 100 largest companies on the London Stock Exchange (by market capitalisation). This includes companies such as Barclays, BP, HSBC and Sainsbury’s.

Can you invest in the FTSE 100?

Yes, but not directly. Many experts talk about investing in the FTSE 100, but it’s not actually an investment fund, it’s an index. Think of an index as a hypothetical portfolio, designed to monitor the performance of the assets it contains (in this case, large-cap UK stocks). As such, you can’t actually invest directly in the FTSE 100.

However, you can gain exposure to the whole FTSE 100 list and companies in the index by either buying shares in each individual firm or by investing in a fund – such as an exchange-traded fund (ETF) or index fund – that tracks the performance of the FTSE 100 index.

Ways to invest in the FTSE 100

There are a couple of ways to invest in the FTSE 100:

  • Buy FTSE 100 stocks directly. You can buy individual shares from the FTSE 100 index using a brokerage or share trading platform. You could buy one share of each company to create your own portfolio of FTSE 100 stocks, or buy shares in selected companies.
  • Invest in a FTSE 100 index fund or ETF. If you want exposure to all the companies in the FTSE 100 without having to buy each stock (and avoiding trading fees), you could instead invest in a FTSE 100 fund or ETF. These track the performance of all the current stocks in the FTSE 100.

The FTSE 100 is made up of some really interesting companies, including Rolls-Royce, AstraZeneca and Abrdn. Because of its appeal, there are lots of funds and ETFs that track the index.

Investors can also choose to invest in all the individual stocks themselves, but this would take a lot of time, because the index changes regularly. You’d need to keep tabs on which stocks have moved out of the index, which have moved in, and whether any weightings need to be changed. An index fund would be much easier and could save you money on trading commissions too.

How do FTSE 100 ETFs work?

A FTSE 100 ETF is traded on stock exchanges. So unlike funds, the price can fluctuate throughout trading hours. Generally, ETFs are cheaper to run than funds (which is why they have low ongoing fees).

An ETF tracking the FTSE 100 also tends to be cheap because it doesn’t require much oversight. The FTSE 100 index is maintained by FTSE Russell and it’s reviewed each quarter. FTSE 100 ETFs should automatically adjust to reflect any changes.

To invest in an ETF, you’ll generally need to pay a fee of around 0.07% to 0.25% each year, as well as any trading commissions charged by the broker.

The ETF’s performance will track closely with the performance of the stocks in the index. For example, if the FTSE 100 increases in value by 2%, your ETF should also increase close to 2%. Your fund returns may be slightly less than the index price returns after investment charges are deducted.

Types of ETFs

Here’s a quick summary of the main types of FTSE 100 ETFs you’ll come across:

  • Market cap weighted ETFs. Most FTSE 100 ETFs will be market-cap weighted and track the performance of the index, meaning the fund is weighted more towards the companies with higher market capitalisation. However, there are some ETFs organised differently, such as the X-Trackers FTSE 100 Equal Weight UCITS ETF (XFEW). As the name suggests, it invests in all the companies in the FTSE 100 index equally. This means the performance of smaller firms will have as much of an impact as the larger stocks.
  • Short ETFs. There are a number of short FTSE 100 ETFs, which effectively bet against the performance of the index. If the FTSE 100 goes down, the value of a short FTSE ETF should go up.
  • Leveraged ETFs. Leveraged ETFs multiply the gains and losses of the index, meaning you’ll get a higher or lower return relative to the size of your investment. You’re effectively borrowing extra capital to potentially increase your returns. For example, if you invest £1,000 in a FTSE 100 ETF with 10x leverage and it goes up 5%, you’d make £500 instead of £50. However, the same magnification would apply to losses.

FTSE 100 ETFs

Below are some of the most popular FTSE 100 exchange-traded funds available. They’re ranked by ongoing costs (this should be as low as possible considering each one mirrors the same investments). Just search the stock ticker on your share dealing account, keep in mind not every platform will have every FTSE 100 ETF.

Expert comment: Why should you invest in the FTSE 100?

Finder Money Expert

Investing in the FTSE 100 tends to be regarded as a relatively safe and low-risk bet – insofar as investing is ever “safe and low-risk”. No investment is risk-free.

Because it’s made up of the UK’s biggest companies, the FTSE 100 tends to include businesses that have been around a while. Companies that have a track record of solid performance. This might mean they’re not the most exciting (or potentially most rewarding) companies to invest in. But the chances of these firms crashing are also lower than average. All of this makes the FTSE 100 a decent option if you want to manage your risk. Plus, if you opt to buy shares, many FTSE 100 stocks pay dividends.

As we always bang on about, though, it’s essential to have a diverse investment portfolio. So, while a FTSE 100 tracker fund will likely feature in many investors’ portfolios, there’s no need to put all your eggs in one basket. There’s nothing stopping you from investing in the FTSE 100, while also bolstering your portfolio with an even lower-risk investment (such as bonds) and a selection of higher-risk, higher-reward assets (like US tech stocks).

Pros and cons of investing in the FTSE 100

Pros

Cons

  • You can’t beat the market if you’re investing in an index copying market performance
  • Little international diversification — you’re only invested in UK shares
  • Less choice. Choosing top FTSE shares can mean missing out on up-and-coming UK stocks.

Bottom line

The FTSE 100 contains some of the best-known British brands, such as Lloyds, Tesco and Rolls-Royce. You can invest in all 100 stocks individually if you have the time. But it could be more expensive this way.

There are index funds and ETFs that track the FTSE 100, which could be a more cost-effective way to get exposure to these stocks. Now that you know how to invest in the FTSE 100 index, make sure you consider the fees involved and that your broker lets you invest in the London Stock Exchange.
