Any PEM followers watch the closing auction....I did! Haven't seen action like that in a long time. The automated selling was active all day (despicable practice) but it wasn't until the last 15-20 minutes that it got interesting. Did you notice the enormous increase in the number of sellers? .....almost doubled then right on the bell (4.00PM) half of them disappeared! BUT, after the bell is where most of the action happened. The buy orders quadrupled to around 6m and the sell orders just about matched them. The result being that the days volume went upwards of 7m of which about half was after the bell. The share price fell by 10.71%.
47.
What to make of all this? .... the small investor gets screwed again!!
Luck
