. But dont hold your breadth past the week, as the rebound or the contuinuation of the trend follows, 1 week
later.
. [Except for year 2004]
. Pattern stops on Year 2008 which was a down year, and 2009 was also a Down year
. followed by 2010 an Up year.
. A new Pattern unfolding ??
. Whatever it is it has been a temporary pause followed by a rally for the next few weeks.
