1. Cimpress N.V. (CMPR) - Get Report

The Netherlands-based business marketing services company broke down hard at the end of July and has been in a rising wedge for six-to-seven weeks now. It has been contained by resistance at the declining top line, and is right near the apex of the wedge. If this breaks, it could be a quick, ugly down-move towards lateral support in the low $60's.

2. Deckers Outdoor Corp. (DECK) - Get Report

Deckers Outdoor, a provider of apparel footwear and accessories, continues to break down. After a massive top broke earlier this year, the stock based for more than six months. It then broke down and snapped back in August, broke down again earlier this month and rallied back to resistance, and has broken down again. This time, however, it broken through lateral support, and looks headed for the bottom of the channel near $50.
