The Dow Jones has risen by more than 40% over the past 17 months. Now the signs are growing that the momentum is weakening. At the same time the Dow could not overcome the mark of 21500 in the last 19 trading days and there is a small triple top. In addition, the volume increases with falling prices and rarely with rising prices. For this reason, we went speculatively short yesterday and our stop is at 21550 and our take profit at 21285.
