I’ve been following Roche returns against some of its competitors over the past while. In the past week, Roche was up 3%, while CIGX was up 3.2%, VVUS was up 3.7%, ARNA was up 3.4%, ABT was up 2.3%, and Chromadex was down 5.7%. Does anyone know why Roche was the middle performer and why Chromadex was on the other end of the performance in the past week?
