What is the FTSE 100?

The Financial Times Stock Exchange 100 (FTSE 100 for short, which is pronounced “footsy”) 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?

You may hear investment experts talk about investing in the FTSE 100, so it’s easy to make the assumption that it is an investment fund. But it’s actually an index. Think of an index as a hypothetical portfolio, designed to monitor the performance of the assets it contains (in this case, stocks in large UK companies). As such, you can’t actually invest directly in the FTSE 100.

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

How to invest in the FTSE 100

  1. Open a share dealing platform. Whether you want to invest directly in FTSE 100 stocks or invest in a FTSE 100 ETF, you’ll need to open an account with a trading platform or brokerage.
  2. Fund your account. You need to put money in your account to buy shares or invest in a fund, either by bank transfer or using a debit card.
  3. Choose your investments. Either select an investment fund or, if you want to buy stocks, do some research into the companies you’re considering. Once you know what you want, find the stocks on your platform.
  4. Hit buy. It’s as simple as that.

Our expert says: Why should you invest in the FTSE 100?

"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 them crashing are also lower than average. All of this makes the FTSE 100 a decent bet if you want to manage your risk levels. 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."

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 stocks 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 individual shares (and avoiding trading fees), you could instead invest in a FTSE 100 fund or ETF. These track the performance of the stocks in the FTSE 100.

The FTSE 100 is made up of some really exciting companies, including Burberry, Coca-Cola and Ocado. 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, especially as the index changes regularly. You would 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 a great deal easier and could save you money on commission too.

Pros and cons of investing in the FTSE 100

Pros

  • Get exposure to the largest stocks on the London Stock Exchange
  • A lot of stocks on the FTSE 100 pay dividends
  • Invest easily with an index fund or ETF

Cons

  • You can’t beat the market if you’re investing in the index that the market is based on
  • No diversification — you’re only invested in UK stocks
  • No choice. Choosing the top stocks on a stock exchange could take the excitement out of choosing stocks.

Bottom line

The FTSE 100 contains some of the best-known British brands, such as Lloyds, Rightmove 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 indices, which could be a more cost-effective way to get exposure to these stocks. Make sure you consider the fees involved and that your broker lets you invest in stocks on the London Stock Exchange.
