FTSE All-Share Index

The FTSE All-Share, or to give it its full name, "The Financial Times Actuaries All Share Index" is the most comprehensive U.K. stockmarket index. It's calculated once a day and is referred to in the market as 'the All-Share'. For the index, see Stockmarket. For past performance, see Rates & Performance.

The 'All-Share' is made up of companies accounting for more than 90 per cent of the market capitalisation of all listed companies on the London Stock Exchange.

The index is an arithmetic mean of 800 shares and fixed interest stocks. These are segregated into different industrial sectors, allowing investors to track the performance of one particular industry and the companies which make it up.

The weightings of the individual companies (the constituents) are calculated according to their size (their market capitalisation, so movements in big companies' shares will have more impact on the index than those of smaller companies. As well as showing price movements, the index shows average yields and price/earnings ratios.

The All-Share Index and its constituent indices have been calculated and published daily since 1962 in the Financial Times in collaboration with the Institute of Actuaries (these are people who found accountancy too exciting).
