As a matter of interest, does anyone have an idea of how much a company converting $3.5Bn into Sterling would be likely to move the market? Sounds like Cairn was trying to do it all in one go, which I would guess is a bit rash.
3 billion in a 2000 billion market has minor impact. The small profit reflects that diminutive impact. Yes, the question stands, how many pence did the 3.5b move ? My guess is 3.56832 pence. Of course this is only a guess, a rough estimate.
