the market cap for example is 400m that doesnt effect the share price in the way your thinking of depends how many shares there are avalible that effect it eg less shares they are worth more, like they are going to do with the consolidation making 10 into 1 the shares at a higher price but the market cap wont change there just worth more cause theres now less shares
this share was worth around 12 pounds back then compared to 28 pence now so double it now and you get???? nothing near 12 pound unless am missing something?
