Key Facts

Understanding the FTSE

The Financial Times Stock Exchange (FTSE) Index, commonly referred to as the FTSE 100, is the primary stock market index of the United Kingdom. It represents the 100 largest companies listed on the London Stock Exchange by market capitalization. The FTSE serves as the main barometer of the health of the British economy and is closely monitored by investors worldwide.

The FTSE Index was first published on January 3, 1984, with an opening level of 1,000 points.

Why the FTSE Matters

The FTSE 100 serves multiple important functions. For investors, it provides a benchmark to measure portfolio performance and overall market trends.

Trading and Investment

The FTSE 100 is heavily traded through various investment vehicles, including index funds, exchange-traded funds (ETFs), and options contracts. Professional and retail investors use FTSE-tracking investments to gain broad UK market exposure. The index is calculated and maintained by FTSE Group, which is owned by the London Stock Exchange Group.
