What is indices trading? A complete guide

Trading indices is a common way to gain access to the stock market without directly trading individual shares or their price movements. Learn all about the potential benefits and risks of indices trading, and why Capital.com is the right place for it.

What are indices?

Indices are groups of exchange-listed stocks compiled to give insight into the performance of companies, wider sectors, and economies in general. The price of indices will rise and fall depending on the performance of the constituent stocks included on each index. Those that trade indices can gain exposure to a wide range of stocks, rather than just one or two. Consequently, indices trading is often seen as a way of diversifying a portfolio. 

When it comes to how to trade indices, financial derivatives such as CFDs give leveraged exposure to the price movements of the underlying market, such as the US 500 (S&P 500), US 30 (US Wall Street 30), Australia 200 (ASX 200) or the Japan 225 (Nikkei 225). It’s these movements that traders attempt to profit on when taking a position. 

Why are indices important?

Indices are important because they act as indicators for key factors such as stock-market confidence, business confidence, the health of the wider economy, and the health of shares investments. When learning how to trade indices, it’s important to understand how these factors can both influence and be influenced by the movement of a given index.

Market analysts will often cite the impact fundamental events such as interest-rate decisions or GDP releases had or are expected to have on the price of certain indices. When trading indices, you should consider following such macroeconomic developments and inform your indices trading decisions by studying the economic calendar for the latest market-moving events.

Trading indices with leverage

Trading indices with CFDs enables you to trade with leverage, meaning you can control large positions with a relatively small amount of capital (known as margin). However, leverage can also amplify losses, so it's important to use it with caution and have a solid risk-management plan in place. 

Major indices on Capital.com have a margin of 0.5%, meaning you only have to put down 0.5% of the total value of the trade, while being exposed to the price movements of the full position. The remaining 99.5% of the value of the trade is effectively advanced to you by us.

Let’s say you’re trading one US Tech 100 CFD contract at a price of 18,000. The total value of the trade is $18,000, but you’ll only have to put down $90 (0.5%) as margin. If the price increases by 30 points to 18,030, you'll earn the full $30 profit. Similarly, if the price fell by 30 points to 17,970, you'll incur the full $30 loss. 

Overall, how to trade indices with leverage will depend on your trading strategy, risk tolerance and market conditions, so ensure you have a comprehensive trading plan in place that explores each of these crucial factors.

Why traders trade indices

Traders may choose to speculate on indices for a number of reasons, ranging from diversification to liquidity to pure speculation. Here are a few of the more common ones. 

Speculation

You may trade an index purely to speculate on the direction of the overall market. This can be done using technical or fundamental analysis to make predictions about market movements and trade indices accordingly.

Diversification

Indices represent a broad range of stocks or assets from a particular market or sector. Trading indices allows you to diversify your portfolio and reduce individual stock risk. Instead of trading individual stocks, you can gain exposure to the overall market.

Liquidity

Major indices like the US 500, US 30, and the Japan 225 are highly liquid, meaning there is a high volume of trading activity. This liquidity makes it easier to enter and exit positions at desired prices.

Access to global markets

You can gain exposure to international markets by trading global indices. For example, you can trade the Japan 225 to access Japanese equities or the US 500 for exposure to US stocks.

Risk management

Trading indices can be a way to manage risk by taking a position in the broader market rather than individual assets. This can help you avoid company-specific risks such as earnings reports or management changes.

Volatility

Some traders are attracted to the volatility of indices, as price fluctuations can provide opportunities for profit, although trading on volatility is a high-risk strategy that could lead to significant losses as well. You might want to employ strategies like day trading or swing trading to potentially capitalise on short-term price movements.

Popular indices to trade

There is a wide range of indices available to trade, which are sometimes calculated by different methodologies. For example, the S&P 500 lists the 500 largest businesses listed on American stock exchanges by market capitalisation, meaning the companies that are the among the largest by such a measure (e.g. Apple) are closest to the top. 

By this methodology, the most-capitalised companies are also weighted more than companies further down the index, meaning that stock price fluctuations in the highest-placed companies may have an outsized impact on the wider index price. 

Other indices, such as US Wall Street 30 (Dow Jones) are weighted by price, with the higher-priced stocks appearing closer to the top and, again, having a larger impact on the index value. 

From the Germany 40 (DAX 40), to the Japan 225 (Nikkei 225), Japan’s benchmark index, to less commonly-traded indices such as the Switzerland 20 (Swiss Market Index), you’ll find the performance of stocks, industries and economies represented all over the world.

How to trade indices with Capital.com

You might want to hedge a liquid index such as the S&P 500 to try and spread your risk vs other global stocks you’re trading. Or maybe you may have specialist knowledge in a lesser-traded index that you feel gives you an edge when speculating on that market.

Whatever your preferred strategy, you can trade indices with Capital.com by following these steps:

• 1. Choose an index CFD to trade, based on your trading goals
• 2. Decide on your trade size
• 3. Consider applying a stop-loss to manage risk
• 4. Open your position long or short
• 5. Manage your position, monitoring fundamental and/or technical drivers
• 6. Close your position

Costs involved in indices trading

As with all of our markets, when you trade indices with us, you’ll pay a spread, which is based on the difference between the buy price and the sell price of the market. For example, if you’re trading the US 100, our spread is 1.8 points, which you will pay on the opening and closing of the trade. The buy and sell prices look like this:

You may also pay additional fees, for example if you use a guaranteed stop-loss or if you hold a trade overnight. As with all Capital.com instruments, you won’t pay any commission when you trade indices.
