FTSE All-Share

The FTSE All-Share stock market index lists the top 600 companies by market capitalisation traded on the London Stock Exchange (LSE) - the UK's primary stock exchange.

The Financial Times Stock Exchange (FTSE) or FTSE Russell Group, is a British organisation that creates and maintains stock market indices, such as the FTSE 100/250/350 and All-Share.

A stock market index measures the price performance of a group of shares from a stock exchange. They can be used as a benchmark of how the market, or a segment of it, is performing. The media often treat indices as indicators of market health. 

The FTSE All-Share lists the top 600 companies by market capitalisation on the London Stock Exchange.

The FTSE indices list the companies traded on the London Stock Exchange by market capitalisation (also referred to as market cap). The market cap is calculated by multiplying the company’s share price by the number of available shares. For example, if a company has 10 million shares selling for £100 each, it would have a market cap value of £1 billion.

FTSE indices, which list companies by market capitalisation traded on the London Stock Exchange (LSE):

• FTSE 100 - lists the top 100 companies
• FTSE 250 - lists the companies ranked 101-350
• FTSE 350 - lists the top 350 companies
• FTSE Small Cap - lists the companies outside of the FTSE 350 index
• FTSE AIM All-Share - lists the companies who have their primary listing on the Alternative Investment Market (AIM), a sub-market of the LSE.
• FTSE techMARK All-Share - lists the companies on the LSE's techMARK market.

When the FTSE is quoted as up it means the total market capitalisation value of all the listed companies added together is higher than the previous market close figure.  Likewise, a drop is if the value has decreased on the previous market close.

When the FTSE hits a new high, this means the total worth of all the indexed companies at market close has increased beyond the previous highest figure in FTSE history.

The companies listed in the FTSE indices are reviewed every quarter, usually in March, June, September and December. 

Any changes to the indices are based on the value of the companies at the close of business the night before the review.
