after hours auction, page-4

Possible reasons for After Hours trades told to me over a few years:

a) Traders making sure all orders are carried out "in the day". Usually, but not wholly, because they've been busy trading and haven't always "got the numbers" right

b) left hand to right hand trading to minimise risk of third party getting involved when the trades are not held by same broker (there is a mechanism for that already, called XT)

c) simply a "late notice order"

d) artifically done to keep apparent turnover higher than would otherwise be the case

e) queue jumping, as per Stockextreme, but always needs a seller at lower or buyer at higher price to succeed.

There's bound to be others so be interested in hearing about them.

In CXY's case the After Hours time has always been interesting, but my guess is it is more to do with the lack of turnover through the day.
