Totally baffles me.
Obviously there is buy orders put place for first 2 minutes of trade./or announcement. Then nothing.
It has happened for months.
Traders could not be doing it as there is so low volume.
The gap is huge sometimes.
For god sakes WMX dropped to $1.13- $1.15 in the last couple of trading days.
Then someone springs at $1.23. Why NOT hold.
No, must sell at $1.15.
What did we end with for the day $1.18. Not good.
Seller a way higher. For tomorrow.
But some clown or Co will sell at $1.19 tomorrow. #?.
