RE:RE:17mil volume?that was a bloomin' mind blowing trading episode. It reminds me of (I think it was) in one of Richard Ney's books, where he described how they, (in the days stock specialists on NYSE), were preparing for a major move upwards in one of the stocks they were in charge of.
As the specialist on that stock, they had the information on all the orders, so they would arrange a raid, driving down the stock until all the stop losses got executed, and in the process, they also flushed all the nervous shareholders.
I think that something similar happened here.
Consider, until today, in the entire month of September until now, UBS had purchased a net total of about $236,000 of K92.
Today ... UBS purchased a net total of $53,589,480 !!! (That was 6,798,467 shares, at an average price of $7.88)
