Ways to invest in indices

If you want to invest in a stock index – or multiple stock indices – the first thing you will need to do is open an account with an online broker. These platforms allow their users to invest in many different ways, including buying a range of shares included in an index, placing trades using CFDs, and using other financial instruments such as ETFs.

A beginners’ guide to investing in stock indices

What is a stock index?

A stock index is a collection of stocks that have been grouped together; indices are used by investors to assess the overall performance of a stock market. As thousands of stocks are often traded on each exchange, it’s no use looking to just one company’s share price when looking for broader trends. Stock indices solve this problem by following the prices of many different stocks – usually those of the largest companies on the exchange.

It’s helpful to think of a stock index as an imaginary investment portfolio. If there are 1,000 stocks that trade on an exchange, then the index that tracks its performance might include the top 100 most valuable ones. Broadly speaking, if these companies do well then the exchange is performing well and the value of the index will rise, and if they perform badly the inverse will happen.

Unlike with a real investment portfolio, however, the performance of a stock index is not given as a monetary value. Instead, the level of each index is represented simply as a number, the level of which is determined by an algorithm designed to give the best indication of the performance of the stock exchange as a whole.

How can I invest in an index?

As an index is not a directly tradeable asset such as a stock or commodity, you cannot buy and sell one directly. Instead, there are a variety of ways you can invest your money to follow the performance of a specific stock index over time, with the most prominent methods being with ETFs (Exchange-Traded Funds) and mutual funds.
