$展讯通信(SPRD)$An upgrade to Buy from Chardan Capital sends Spreadtrum (SPRD +3.5%) higher. The upgrade comes shortly after chairman/CEO Leo Li told the EE Times Spreadtrum is a major beneficiary of China's low-end smartphone boom. Li touts the appeal of Spreadtrum's low-cost 1GHz., single-core, 2G and 3G baseband/app processors, and notes the company's efforts to develop 3G WCDMA and 4G TD-LTE processors. However, the site observes Spreadtrum is increasingly butting heads with MediaTek, which has a stronger mid-range smartphone position.
