FAQs

How are stock indices priced?

Stock indices are priced in a range of ways, based on the value of their constituents. A price-weighted index, for example, gives greater emphasis to the higher-priced stocks among its constituents. So the higher a constituent company’s share price, the more influence that company has on the index’s movement.

By contrast, a capitalisation-weighted index gives emphasis to the companies among its constituents with the highest market capitalisation – or rather, the market value of their outstanding shares.

At IG, we base our index market prices on futures contracts in the underlying market.

What influences stock index movement?

The price of a stock index is influenced by a range of factors. As a collection of share prices, perhaps the most obvious factor that affects index movement is the price of its constituent stocks. However, indices are also affected by a range of economic and political events.

Options and futures are complex instruments which come with a high risk of losing money rapidly due to leverage. They’re not suitable for most investors. Before you invest, you should consider whether you understand how options and futures work, the risks of trading these instruments and whether you can afford to lose more than your original investment.

Trading stocks and shares ‘on margin’ within a US options and futures account – meaning that you only finance part of the cost of acquiring a position in a security – carries additional risks over buying securities on a fully funded basis and may result in losses exceeding your original investment. Trading on margin will also result in additional costs to you as the investor and any securities purchased using margin may be held as collateral by the lender, restricting both your rights as shareholder, and your ability to use the securities until the margin trade is closed. You should familiarise yourself with these risks before trading on margin.

The value of shares, ETFs and other ETPs bought through a share dealing account, a US options and futures account, a stocks and shares ISA or a SIPP can fall as well as rise, which could mean getting back less than you originally put in. Past performance is no guarantee of future results. Some ETPs carry additional risks depending on how they’re structured, investors should ensure they familiarise themselves with the differences before investing.
