What are indices?

Indices are a measurement of the price performance of a group of shares from an exchange. For example, the FTSE 100 tracks the 100 largest companies on the London Stock Exchange. Trading indices enables you to get exposure to an entire economy or sector at once, while only having to open a single position.

You can speculate on the price of indices rising or falling without taking ownership of the underlying asset with CFDs. Indices are a highly liquid market to trade, and with more trading hours than most other markets, you can receive longer exposure to potential opportunities.

How are stock market indices calculated?

Most stock market indices are calculated according to the market capitalisation of their component companies. This method gives greater weighting to larger cap companies, which means their performance will affect an index’s value more than lower cap companies.

However, some popular indices – including the Dow Jones Industrial Average (DJIA) – are price-weighted. This method gives greater weighting to companies with higher share prices, meaning that changes in their values will have a greater effect on the current price of an index.

What are the most traded indices?

  1. DJIA (Wall Street) – measures the value of the 30 largest blue-chip stocks in the US
  2. DAX (Germany 40) – tracks the performance of the 30 largest companies listed on the Frankfurt Stock Exchange
  3. NASDAQ 100 (US Tech 100) – reports the market value of the 100 largest non-financial companies in the US
  4. FTSE 100 – measures the performance of 100 blue-chip companies listed on the London Stock Exchange
  5. S&P 500 (US 500) – tracks the value of 500 large cap companies in the US

How to identify what moves an index’s price

An index’s price can be affected by a range of factors, including:

  • Economic news – investor sentiment, central bank announcements, payroll reports or other economic events can affect underlying volatility, which can cause an index’s price to move
  • Company financial results – individual company profits and losses will cause share prices to increase or decrease, which can affect an index’s price
  • Company announcements – changes to company leadership or possible mergers will likely affect share prices, which can have either a positive or negative effect on an index’s price
  • Changes to an index’s composition – weighted indices can see their prices shift when companies are added or removed, as traders adjust their positions to account for the new composition
  • Commodity prices – various commodities will affect different indices’ prices. For example, 15% of the shares listed on the FTSE 100 are commodity stocks, which means any fluctuations in the commodity market could affect the index’s price

Go long or short

When index trading with CFDs, you can go long or short. Going long means you are buying a market because you expect the price to rise. Going short means you are selling a market because you expect the price to fall.

With CFDs, your profit or loss is determined by the accuracy of your prediction, and the overall size of the market movement.

Indices trading

Trade with leverage

CFDs are leveraged products. This means you only need to commit a small initial deposit – known as margin – to open a position that gives you much larger market exposure.

When trading with leverage, you should remember that your profit or loss is calculated using the entire position size, not just the initial margin used to open it.

Indices trading: trade with leverage

Hedge your existing positions

An investor with a collection of different shares might short an index to protect themselves from losses in their portfolio. If the market enters a downturn and their shares start to lose value, the short position on the index will increase in value – offsetting the losses from the stocks. However, if the stocks increased in value, the short index position would offset a proportion of the profits which had been made.

Alternatively, if you had a current short position on several individual stocks which feature on an index, you can hedge against the risk of any price increases with a long position on that index. If the index rises, your index position will earn a profit, counteracting a proportion of the losses on your short stock positions.

Choose how to trade indices

With IG Bank, you can use CFDs to trade indices. These products are financial derivatives, which means you can use them to speculate on indices that are rising in value, as well as falling.

CFDs are a contract between two parties to exchange the difference in price from the point at which the contract is opened, to the point at which it is closed.

Decide whether to trade cash indices or index futures

When you trade with IG Bank, there are two ways to get exposure to an index’s price: by trading cash indices or index futures.

Cash indices

Cash indices are favoured by traders with a short-term outlook – such as day traders – because they have tighter spreads than index futures. Cash indices are traded at the spot price – which is the current price of the underlying market.

Many traders will close their cash indices positions at the end of the trading day and open new positions the following morning to avoid paying overnight funding charges.

Index futures

Index futures are often preferred by traders with a long-term market outlook. This is because, while they have wider spreads than cash indices, the overnight funding charge is included. Index futures are traded at the futures price – the price that futures traders agree in the present for delivery in the future.

If you plan on holding on to an index position for a long time, trading index futures will mean that you don’t incur frequent overnight funding charges.

CFDs

Min. cash spread Min. futures spread
Wall Street 2.4 6
Germany 40 1.2 6
US Tech 100 1 3
FTSE 100 1 4
US 500 0.4 1

Aside from cash indices and index futures, you can also trade index ETFs and individual shares with IG Bank. Again, you can open these positions with CFDs.

To start trading indices with CFDs today, open an account with IG Bank. IG is a FTSE 250 company with over 45 years’ experience, present in Switzerland since 2014. Our spreads are among the lowest in the industry, and we have a larger offering of weekend index markets than any other Swiss provider.

Select the index you want to trade

It’s important to choose an index that’s best-suited to your trading style. This will depend on your individual appetite for risk, available capital and whether you prefer taking short-term or long-term positions.

For example, the Germany 40 is usually a volatile index which is favoured by traders with high risk appetites and who prefer short-term trading. On the other hand, the US 500 is largely known for its steady returns over time, making it a favourite with traders with lower appetites for risk and a long-term outlook.

IG offers over 80 index markets on both major and minor global indices1, meaning that you’re more likely to find a market that fits your individual trading style.

Decide whether to go long or short

Going long means that you are speculating on the value of an index increasing, and going short means that you are speculating on its value decreasing.

If the economic outlook for an economy or sector looks good based on the performance of the companies on an index, a long position could help you realise a profit if the index increased in value.

If the outlook is poor – possibly because large companies on a capitalisation-weighted index are underperforming – you might want to go short on the expectation that the index will fall in value.

Set your stops and limits

Stops and limits are essential tools for managing your risk while trading indices. A stop order will close your position automatically if it goes to a less favourable level than the current market price, while a limit order will close your position automatically if it goes to a more favourable market price.

Open and monitor your trade

When you think you’re ready to start indices trading, it’s time to open your trade. To do this, go to the market you want to trade on the IG trading platform – Wall Street for example.

Next, decide whether you want to deal at the cash price or the futures price – and select buy if you think the price will rise, or sell if you think the price will fall. Enter your position size, and click ‘place deal’ to open your trade.

Monitor your position, and close your trade when you want to take a profit or cut a loss.

FAQs

What does indices trading mean?

Indices trading means that you are taking a position on a stock index – which is measure of the performance of several different companies. Indices trading can be a way to get exposure to an entire sector or economy at once, without having to open positions on lots of different shares.

Can I profit from index trading?

You can profit from index trading by accurately predicting an index’s price movements. For example, if you think the FTSE 100 will rise, you would open a long position. But, if you think it will fall, you would open a short position. Your profit or loss is determined by the extent to which your forecast is correct.

What does it mean to buy index futures?

To buy index futures means that you are opening a long position on an index because you think the price will increase. If you are correct in your forecast, you will profit, but if you are incorrect, you will incur a loss.

Are index futures derivatives?

Index futures are a financial derivative. Their price is based on the price in an underlying market, which is influenced by supply, demand and volatility. You can speculate on index futures with CFDs, and they will be traded at the futures price – meaning that you won’t incur overnight funding charges.

How can risk be hedged with stock index futures?

You can hedge risk with index futures by taking a position that will turn to profit if one or more of your existing positions starts to lose money. For example, if you held long positions on a selection of US tech stocks, you could open a short position on the US Tech 100 to offset any losses you might incur from the shares declining in value.

Alternatively, if you held short positions on a collection of large-cap UK shares, you could open a long position on a FTSE 100 index future to protect yourself against any possible increases in the price of the underlying shares.

Can I sell futures before expiry?

You can sell futures before expiry, and many traders will exit their positions before the expiry date arrives. To do so, you can sell your contract outright or purchase an opposing contract which cancels out your current position.
