The FTSE 100<\/strong>, short for the Financial Times Stock Exchange 100 Index<\/strong>, is a stock market index<\/a> that tracks the 100 largest companies listed on the London Stock Exchange (LSE) by market capitalisation. It is one of the most widely followed benchmarks for measuring the performance of the UK equity market. <\/p>\n Often referred to as the “Footsie”<\/strong>, the FTSE 100 includes many of the UK’s best-known companies across sectors such as financial services, energy<\/a>, healthcare, consumer goods, and mining. <\/p>\n In simple terms, the FTSE 100 provides a snapshot of how the largest UK-listed companies are performing and is commonly used as an indicator of market sentiment and economic confidence.<\/p>\n The FTSE 100 is a market capitalisation-weighted index<\/strong>, meaning that larger companies have a greater influence on the index’s performance than smaller constituents.<\/p>\n The value of the index changes throughout the trading day as share prices of the constituent companies rise and fall.<\/p>\n The index is reviewed quarterly, and companies may enter or leave the FTSE 100 depending on changes in their market capitalisation.<\/p>\n Before looking at individual companies, it is useful to understand that the FTSE 100 does not represent the entire UK stock market<\/a>. Instead, it focuses on large-cap businesses that account for a significant portion of the London Stock Exchange’s total value.<\/p>\n The FTSE 100 contains some of the largest and most established businesses listed in the UK. Constituents change over time as company valuations rise or fall. <\/p>\nHow does the FTSE 100 work?<\/h2>\n
