Financial Times All-Share Index
An index tracking approximately 600 publicly-traded companies listed on the London Stock Exchange and representing approximately 98% of the LSE's market capitalization. Like many other FTSE indices, it is calculated in real time, with prices updated every 15 seconds. Each quarter, the FTSE reevaluates the companies tracked on the index and makes necessary adjustments to ensure that it represents the correct companies. It includes all companies tracked by the FTSE 100, the FTSE 250, and the FTSE Small Cap. It is weighted for market capitalization.
