I consider the '87 monthly chart to be anomalous and the 2012 chart normal. The Fed action is enough to provide the fourth step. imo, as noted by LespaulRocker, we may appear to ride the old upper channel line but will actually be riding in a new channel a step up from the old. The Fed has the long's back. Depending on external events of course, this rally has a good chance of lasting well into the Spring of the new year.
