In a prior post (here), I compared the similarity of the piecemeal way that UBS, Merrill Lynch and Citibank have disclosed their subprime-related asset valuation write-downs. Now UBS has one more thing in common with the other two banks – it has been named as a defendant in a securities class action lawsuit.
On October 30, 2007, UBS issued a press release announcing its financial results for the third quarter of 2007. In the days following this announcement, the price of UBS stock declined to as low as $49.27 per share. Then, on December 10, 2007, UBS announced writedowns of around $10 billion as a result of its subprime mortgage related positions. Following this announcement, the price of UBS stock declined to $48.78 per share, a 26% decline from the Class Period high. The action purports to be brought on behalf of all shareholders who purchased UBS stock between March 13, 2007 and December 11, 2007.
