Post 6613 is as good and reasonable an explanation as might be proffered at this time.
Absent a deal bubbling up, there can be no other explanation. ... If this "spike" occurred in anticipation of a deal, one would expect millions of shares to be traded. ...NOT 10000 !
FOR THE HISTORY - - - to provide an example - - - look at the few days leading up to the GRSI deal announcement, when many millions of shares were sold, and the price jumped dramatically - - - when the news of the deal was "leaked" some days ahead of the official announcement .
