Trading the FTSE 100

Trading is the only way to get direct exposure to the FTSE 100’s price movements. If you want to gain exposure to the FTSE 100, you can use CFDs to speculate on price movements.

When trading, you can gain full exposure with only a small deposit (called margin) and you do not take ownership of any assets. That means both profit and losses can be hugely magnified compared to your outlay, and that losses can exceed deposits.

Investing in the FTSE 100

If you want to invest in the FTSE 100, you can buy shares in ETFs that track the price of the index or shares of individual constituents. The aim is to make a profit when you sell the shares at a later date. You could also receive dividend payments if made.

When investing, you need the full value of the position upfront, and you’ll take ownership of the shares. You can buy UK shares with no commission charge.1

Ways to trade the FTSE 100 with IG

When trading with IG, you can get exposure to an index’s price by trading the following:

Cash index CFDs

Trading cash index CFDs means dealing at the current price of the underlying market. Cash indices are popular with short-term traders because they offer some of our tightest spreads. However, if you keep cash index positions open overnight, an additional funding charge will apply.

Index futures CFDs

Trading index futures CFDs means you agree to trade the index at a specific price on a specific date (i.e. the expiry date). Index futures are popular among longer-term traders because the overnight funding charge is included in the spread – enabling you to hold positions for a long time without this additional cost.

Get round-the-clock exposure to thousands of global markets, including indices, forex and shares.

Ways to invest in the FTSE 100 with IG

With a share trading account, you can get exposure to the FTSE 100 by investing in:


When you invest in a FTSE 100 ETF, you are essentially spreading your capital out across the top 100 companies in the UK. The most common form of FTSE 100 ETF is a weighted tracker, which mirrors the make-up of the FTSE 100 directly. Examples of weighted trackers include the Vanguard FTSE 100 UCTIS ETF and the iShares Core FTSE 100 UCITS ETF.


You can invest directly in constituents of the FTSE 100 with the aim of selling them for a profit later. FTSE 100 stocks are popular among investors, partly because they often pay healthy dividends. Some examples of FTSE 100 stocks include Ocado, which has risen over 400% since Q4 2017, Barclays – with its healthy dividend yield, and defensive stocks such as AstraZeneca.

With IG, you can enjoy flexible access to more than 13,000 markets, including ETFs and individual shares.

What moves the FTSE 100’s price?

The FTSE 100’s price is moved by factors including:

  • Economic events - Events such as Brexit, can have a significant impact on the price of an index. Since the 2016 referendum, the FTSE 100 has tended to move inversely with the pound.
  • Exchange rates - Fluctuating exchange rates can affect the FTSE 100’s price because its constituents earn a lot of their income in other countries.
  • News releases - Certain news releases are generally followed by a period of volatility in the market. If the news pertains to any of the industries or constituents of the FTSE 100, its price may be affected.
  • Earnings reports - Changes to FTSE constituents’ valuations can have a substantial impact on the index price, depending on the weight of the stock.
  • Commodity prices - Because around 15% of companies on the FTSE 100 are commodity stocks, commodity price fluctuations can influence the index’s price quite heavily.

Traders should always use a combination of fundamental analysis and technical analysis before trading the FTSE 100, and follow their trading plan and risk management strategy.

FTSE 100 calculation and trading hours

The FTSE 100 is an index of the UK’s largest 100 public companies by market capitalisation. It has become a popular way to gain exposure to the UK stock market and track the performance of the country’s economic health.

The market capitalisation of the index has grown significantly since its inception in 1984, as its constituents have experienced success and growth.

How is the FTSE 100 calculated?

The FTSE 100 is calculated by weighing all stocks listed on the London Stock Exchange (LSE) by market capitalisation. The 100 companies with the highest market cap make it onto the index. Companies with a higher market capitalisation will represent a higher weight in the index and stocks with higher weightings have a bigger effect on the FTSE 100’s price.

What are the FTSE 100’s trading hours?

The FTSE 100’s trading hours are 8am to 4.30pm UK time (5pm to 1.30am AEST). IG also offers exclusive weekend trading hours for the FTSE 100, from 4am on Saturday to 10.40pm on Sunday (1pm Saturday to 7.40am Sunday AEST).


What are the ways you can trade or invest the FTSE 100?

You can trade the FTSE 100 via CFDs on cash indices or index futures. While you cannot invest directly in the FTSE 100, you can invest in FTSE 100 ETFs or in individual company shares listed on the index via our share trading service.

What should you know before trading the FTSE 100?

Before trading the FTSE 100, make sure you do your research and understand how the index works. Then, decide whether you want to trade or invest.

How do companies get onto the FTSE 100?

To get onto the FTSE 100, a company must be listed on the London Stock Exchange (LSE) and it must be one of the top 100 companies by market capitalisation on the exchange. If its market capitalisation drops drastically, a company might lose its listing on the FTSE 100.
