China's markets have stumbled, but its top tech stocks could rise 20% this year, analyst says  

• Ray Wang, principal analyst at Constellation Research, predicted that the Baidu, Alibaba and Tencent — the so-called BAT stocks — will go up by between 15 and 20 percent by the end of the year.
• That's despite steep losses on Tuesday and Wednesday for Tencent as China reportedly halted approvals for game licenses, and blocked the sale of a video game on Tencent's platform.
• Wang said those top Chinese technology conglomerates will be resilient against any trade war escalations.
