I made a mistake. the x-div date is the 12th. Here is the quote from the geo webpage:
On December 6, 2012, GEO's Board declared a special dividend of $5.68 per share of common stock, representing approximately $350 million of accumulated earnings and profits, which will be paid on December 31, 2012 to shareholders of record as of December 12, 2012.
Does this mean that we have to have shares at the close of 12/12/12? Why the dumping today and all the buying on thursday and friday?
