Alibaba plans to launch its New York stock market debut in the week of Sept. 8, a person briefed on the matter told Reuters in late August. “From the very beginning our founders have aspired to create a company founded by Chinese people but that belongs to the world,” Executive Chairman Jack Ma said in a regulatory filing with the U.S. Alibaba, in which Yahoo Inc currently holds a stake of 22.4 percent, will decide on its final price after a globe-spanning roadshow expected to kick off in coming days.
