About FTSE 100 (UKX)
The FTSE 100 is a market index that tracks 100 of the largest companies listed on the London Stock Exchange. It is widely used as a benchmark for the UK equity market.
The index is a market-capitalization-weighted measure of its constituents, many of which generate significant revenue internationally. It represents market performance rather than a company.
The FTSE 100 is commonly followed as a benchmark for UK large-cap equities and as a reference point for the London market. Historical performance can be influenced by global commodity and energy exposure, the value of the British pound, interest rates, and broad economic conditions.
This calculator uses available historical data to illustrate past returns over selected periods. It does not evaluate whether the index is a good or bad investment, and index values cannot be purchased directly.
