Definition: FTSE100

The FTSE100 is the index for shares of top 100 companies (in terms of market capitalization) on the London Stock Exchange.

The index was launched on 3rd January 1984 with a base level of 1000. The total market capitalization of the FTSE100 companies is around 81% of the London Stock Exchange.

The FTSE Group, a joint venture between Financial Times and London Stock Exchange, maintains the index. The calculation of the index is done real time and posted in every 15 seconds. It is one of the most widely recognized indices globally and is similar to the NIFTY of India.

A

500

10%

$75000

B

$200

600

15%

$120000
