UK100

The FTSE 100 Index, represented on TradingKey as UK100, measures 100 highly capitalized blue-chip companies listed on the London Stock Exchange that meet FTSE Russell's eligibility rules. It is weighted by investable market capitalization after free-float adjustments, giving companies with greater publicly tradable market value more influence. The constituent list is reviewed under FTSE UK Index Series rules. Many constituents earn substantial revenue overseas, so the index is not a complete proxy for the domestic UK economy. UK100 performance can be affected by commodity prices, bank profitability, pharmaceutical earnings and sterling. A weaker pound may support the translated value of overseas earnings, but this relationship varies. The FTSE 100 cannot be purchased directly; exposure may be available through funds, ETFs, futures, options or CFDs. A UK100 quote may track an index-linked product and trade outside London's cash session, causing differences from the official index. Consider trading hours, dividends and financing when interpreting the chart.
