London Stock Exchange (LSE)

One of the oldest and largest stock exchanges in the world, tracing its origins back to the coffeehouses of 17th-century London. The LSE is the primary exchange for UK-listed equities and a major venue for international companies seeking European capital. Its FTSE 100 index, comprising the 100 largest companies by market cap, is the most widely followed benchmark for British stocks and a barometer of the UK economy.
