See our previous blogs on DE. You are now down about 25% since we recommended selling this stock (and similar ones like CAT). At first we expected a 4th wave around this level and that appears to be what we got, at least it is a triangle. However triangles can be either a 4th wave or a B wave. Given the size relative to wave 2 it has occurred to us that this may in fact be a B-wave (in pink). The consequence of such a change is that we are already in a wave C and could continue the drop much faster than in the other interpretation.
Time will tell.
