When Jack Ma founded Alibaba 15 years ago he insisted the e-commerce venture should see itself as competing against Silicon Valley, not other Chinese companies. That bold claim from a time when China was still a corporate backwater has been vindicated by Alibaba completing a mammoth sale of shares to investors in the U.S. and elsewhere. The shares start trading in New York on Friday, Sept. 19, 2014. (AP Photo/Vincent Yu, File)
