As we reported a couple of weeks ago, Aston martin has issued shares for the first time and these started trading today.
The shares have been priced at £19 a share, valuing the firm at £4.3, but have fallen by 5% during the first couple of hours of trading.
It is the first UK carmaker to sell shares in years and has a glamorous association with James Bond films.
The shares are currently trading on a conditional basis, an introductory and more limited period of trading applied to newly listed shares whilst full trading beings on Monday.
The share sale will raise at least £1bn for the firm. Aston Martin has a further number of shares it will release if demand is strong enough, which would mean 27% of the company would be publicly traded.
