Qualcomm (QCOM -1.8%) gets pulled from Goldman's Conviction Buy list. The firm, which maintains an $80 PT, thinks Qualcomm's chip market share will likely peak this year. Qualcomm is about to see tougher 4G baseband competition (I, II), and the arrival of 4G-only phones could diminish the value of its multi-mode expertise. On the other hand, the company maintains a big edge for now when it comes to 4G baseband/app processors. Also: Nomura isn't impressed with Qualcomm's buyback plan, arguing it won't lower its share count if spread out over 2 years.
