We've got a very clear head-and-shoulders pattern on the 1d chart for DD, starting last October and culminating this month. As with TWTR, our pattern is reaching its resolution in coordination with earnings.
There is a very small chance that we could have a pop off the 41.05 line if we look at the leg down as a falling wedge, but the head-and-shoulders distribution pattern outweighs what would be a very sharp possible accumulation pattern.
44.42 is an estimated support line based on the accumulation period from May-July '13 and the hammer on 2013-08-07. The major breakdown level will be at 41.05, with no significant support to hold us up until 36.05, with a possible bottom at ~32.
