Baidu (BIDU -4.9%) dives for the second time this week (previous) following a downgrade to Hold from Deutsche. The firm predicts Baidu will lose share to Qihoo's (QIHU -3.4%) new search engine due to the latter's giant web browser user base (272M users, or 51% of China's Internet base, according to Qihoo), and the "reasonably good user experience" of Qihoo's engine. But is that engine making use of Baidu's IP and/or search data?
