Put into its simplest term, the FTSE 100 is a share index of the 100 most highly capitalised UK companies listed on the London Stock exchange. The name itself, FTSE, is a combination of the two founding organisations which still maintain the index today as an independent company - the Financial Times and the London Stock Exchange.
