The FTSE 100 is a widely used stock market index that measures the daily share price performance of the top 100 UK companies listed on the London Stock Exchange (LSE).
It not only provides real-time information on the performance of UK shares, tracking market trends, and offering insight to guide investment decisions, but the FTSE is also a guide to how the stocks, shares and economy have performed since its creation in 1984.
The index comprises household brands such as Tesco (TSCO), Morrisons (MRW) and Vodafone (VOD) and high-street banks including Barclays (BARC), Lloyds Banking Group (LLOY), RBS (RBS) and HSBC (HSBA), as well as some of the world's leading service and manufacturing companies such as BP (BP) BT (BT.A), Centrica (CNA) and Rolls Royce (RR). And because the FTSE comprises the biggest market performers, it's regularly used to monitor the ups and downs of particular businesses and the economy.
These 100 blue-chip organisations are reviewed quarterly, ensuring that all companies listed on the LSE that are eligible for the FTSE UK indices are ranked in order of their size or market capitalisation. Market capitalisation is calculated by multiplying the number of shares a company has available for investors to buy and the current share price.
Individual share prices of each company affect the total market capitalisation, so the index value changes throughout the day as share prices go up or down. The index is calculated every 15 seconds on every week day (excluding public holidays) from 08:00 to 16.30 when the market closes. When the FTSE100 is up or down, the change is quoted against the previous day's closing figures.
