Even if you couldn’t care less about investing, you’ve probably heard of the FTSE 100. The FTSE 100 is the best-known stockmarket index in the UK. In effect, it sums up the fortunes of Britain’s biggest listed companies into one single number, by combining them all into one hypothetical portfolio.
If you invest with a fund manager who says they will put your money into big UK companies, then how do you know if they are doing a good job or not? One way to tell would be to compare their performance to that of the FTSE 100. If they manage to beat the index over the long run, it suggests that their stockpicking skills are adding some value for you. If not, then why pay them to manage your money?

There are many different ways to construct an index. Most indexes, including the FTSE 100, are based on market capitalisation – that is, the share price of each company multiplied by the number of shares outstanding. In other words, the companies deemed most valuable by investors carry the most weight in the index.
The best-known indexes tend to be the ones that represent individual countries’ stock markets. Other indexes you may well have heard of include the Dow Jones or the S&P 500 in the US, and the Nikkei in Japan. However, there are literally thousands of different indexes available, and there are many different ways to build them.
As passive investing – which aims to track an index, rather than beat it – has boomed in popularity, index providers have become huge businesses. As investor demand for index funds that track specific themes, or specific investment styles has grown, index providers have created custom indexes to back these investment products.
Some fear that the boom in indexing may distort the flows of money into financial markets in disruptive ways. However, there is no doubt that index funds can be a very convenient and cheap way to build a diversified long-term investment portfolio.
