I assume you are right about the hot money but it feels more orderly than that (ignoring AIM for 2 days there). I'd like to have a history of the weekly top 20 for the last 3 months - I reckon that would tell us the truth.
But you are right about the next few days - news or not I suspect if we have hot money we will see sellers pre christmas - if we don't see that then we might actually have a majority of longer term holders.
