Can someone explain to me how this works?
e.g. I can see (according to FT) AMD ended the day at $33.13, but this ended on $33.31 after hours (according to Google).
The buy price on FT is still $33.13, and the market doesn’t open until 2:30pm UK time…
So a semi serious question - Does this mean if I buy a share now it will cost me $33.15, and I’ll make 16p profit by the time 2:30pm comes around? (It quite clearly won’t mean that, but I want to understand why…)
