Apple, Up 38% in 2017, Left Trailing by Alibaba, Tencent

China's top two internet companies have gained about 70 percent

Fans of Apple Inc. watched in delight as shares soared 38 percent this year. But compared with China’s tech heavyweights the iPhone maker is a wimp. Alibaba Group Holding Ltd. is up twice as much -- 76 percent -- while Tencent Holdings Ltd., which like Alibaba is due to release results this week, has risen 71 percent. During July, Apple was outpaced by its key manufacturing partner, Taiwan’s Hon Hai Precision Industry Co., better known by the trade name Foxconn.
