Harry has posted a Charts of the Day video on SIRO at TheTechTrader site noting: Sirona Dental Systems Inc. (SIRO), after breaking down in May, is in a rising wedge. It formed a bear flag, and then broke the lateral support. The run-up got right up to that level and the declining topsline parallel-channel top. It was up 36 cents on Wednesday, but if it rolls over, the signal would be below 66 3/4. That could drop it significantly. It has 4 legs down, so look for a 5th leg down towards 60.
