It is a glory day for the bulls. It's not because Fed's decision, actually Fed just did a wrong thing again, which will hurt US economy later. (Fed should not cut rate at all consider the extremely weak dollar. ) Today's rally is due because of wave structure. It expressed as extreme bearish sentiment and oversold condition. It is due for a strong bounce regardless Fed's decision.
But it is also true that this kind of bounce needs consolidation to become sustainable. In the next few days, we should see some consolidation before this rally grows a leg.
So don't over joy the super ride, road ahead still bumpy.
