Just look at last month the 3rd Friday was October 18th. Close the night of Wednesday Oct 16 was $51.14, close the night of Thursday Oct 17 was $52.21, and close on Friday Oct 18 was $54.22. Pros control it and they will squeeze the hedge funds and shorts that have to keep honest the closure of their short positions.
GOOG has 5 million shares of short interest as of September 30, 2013 so there is going to be a lot of short squeeze covering by some pretty distressed investors who wasted investment dollars betting against an amazing technology dominant company.
So 81 million shares crossed at the same closing price of about 22.65 or so. I can believe that means there were buyers wanting 81 million shares ... Who in the heck sold out their 81 million shares at that price. I would never have sold my shares I would have made them bid the price upwards. Still seems like manipulation in some way.
Delta paid the dividend on September 10 to all shareholders who owned stock at the close of the market on August 6th since the Ex-Dividend Date was August 7th. Anybody owning the stock on August 7, 2013 or later would not qualify to participate in the dividend.
