Qihoo (QIHU -4.4%) slides as investors mull the impact of Baidu's (BIDU +4.9%) purchase of Chinese app store owner 91 Wireless on Qihoo's rival Mobile Assistant app store. Baidu will likely try to bundle 91's app store with its existing arsenal of mobile apps/services for OEMs, and also pitch its developer partners on publishing their apps to the store. Stifel is defending Qihoo: the firm thinks Mobile Assistant handled more downloads than 91 Wireless in the 6 months ending Jan. '13 (7B vs. 6.2B). Meanwhile, ABR defends the steep price Baidu paid: it thinks 91's rapid growth could lead it to contribute $0.11-$0.17 to 2014 EPS.
