The Financial Times Share Indexes are a number of share indexes published by the Financial Times, daily except Sundays and Mondays, as a barometer of share prices on the London Stock Exchange. The Financial Times Actuaries Share Indexes, of which there are 54, are calculated by the Institute of Actuaries as weighted arithmetic averages for various sectors of the market (capital goods, consumer goods, etc.) and divided into various industries. These are used widely by investors, portfolio managers, etc. The Financial Times Ordinary Share Index represents the movement of industrial shares on the basis of 30 market leaders. An unweighted geometric average, it is published twice daily (noon and the close of business) and gives an indication of market mood. The more recent Financial Times Stock Exchange 100 Index (FTSE 100 Index, known as FOOTSIE) is based on the price of 100 securities and gives the best overall indication of market movements on a daily basis.
