As previously reported, Deutsche Bank analyst Eileen Deng downgraded Weibo (WB) to Hold from Buy as she sees risk to the advertising industry from the macro environment and risk to MAU growth due to smartphone softness and her view on neither of those risks was changed by listening to the company's Q4 results call. She edged up her price target on Weibo shares to $71 from $70, but sees a lack of catalysts for a meaningful earnings revision, Deng said in a post-earnings note. She also downgraded Sina (SINA) to Hold from Buy with an unchanged price target of $70, stating that in addition to the risks to Weibo's financials, she sees greater impact on the Sina portal from the macro weakness and from competition.
