FTSE techMARK All-Share

The FTSE techMARK All-Share market index measures the performance of companies by market capitalisation traded on the London Stock Exchange (LSE) techMARK. The LSE's techMARK is a market for innovative technology companies. 

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 FTSE techMARK 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 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), include:

• FTSE 100 - lists the top 100 companies
• FTSE 250 - lists the companies ranked 101-350
• FTSE 350 - lists the top 350 companies
• FTSE All-Share - lists all 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

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 FTSE techMARK All-Share index consists of all the companies listed on the London Stock Exchange’s (LSE) techMARK market.

If a company is delisted from the techMARK market, it’s removed from the FTSE techMARK All-Share index.

All companies applying for the LSE’s techMARK market are assessed individually by the LSE with advice from an independent panel of experts, where necessary. If successful they’re then reviewed on a quarterly basis.
