The FTSE 100 is a stock market index that tracks the performance of the 100 largest companies listed on the London Stock Exchange by market capitalization. It is a key indicator of the UK stock market and economy.
Description: The FTSE 100 Index, commonly known as the Footsie, is a share index of the 100 companies listed on the London Stock Exchange with the highest market capitalization. Launched on 3 January 1984, it is maintained by FTSE Russell, a subsidiary of the London Stock Exchange Group. The index is widely used as a benchmark for investment performance and represents about 81% of the entire market capitalization of the London Stock Exchange. Constituents are reviewed quarterly and must meet certain criteria, including free float and liquidity. The FTSE 100 is a market-capitalization-weighted index, meaning larger companies have a greater impact on its value. It covers various sectors, with financials, energy, and consumer goods being prominent. The index is often used by investors to gauge the health of the UK economy and is a popular underlying for exchange-traded funds (ETFs) and derivatives.
