The FTSE 100 is a market-capitalisation weighted index representing the performance of the 100 largest UK-domiciled blue chip companies, which pass screening for size and liquidity. The index represents approximately 84.35% of the UK’s market capitalisation and is suitable as the basis for investment products, such as funds, derivatives and exchange-traded funds. The FTSE 100 Index also accounts for 8.02% of the world’s equity market capitalisation (based on the FTSE All-World Index as at 30 June 2011).
FTSE 100 constituents are all traded on the London Stock Exchange’s SETS trading system.
The indices are managed according to a transparent and public set of index rules,
and overseen by an independent committee of leading market professionals. The
committee ensures that the rules are correctly applied and adhered to. Regular
index reviews are conducted to ensure that a continuous and accurate representation
of the market is maintained.
