Regarding trackers if the fund is fully replicating it will have to buy all stocks in the particular index pro rata. But most are samplers only when they will have most of the main ones. Complicated ain't it?
Your message yesterday 19.21 "it'll be back over £2 within days". Alice a mergers would we'll be positive for Sp and not even a rate rumour re acquisition unless you are trying to start one?
I do not think it will be back over £2 in a few days having gone xd yesterday. This is the way it usually works in the market. I am sure you already know this?
