According to Executive Vice Chairman Joe Tsai, "Yahoo! has made a priority to build a good relationship with Alibaba." That's a good relationship to have: Yahoo's stock moved up to $34.54 on October 22, mainly on a report that Alibaba got a thumbs-up from the Nasdaq and the New York Stock Exchange on how it plans to file its IPO. Should that company go on to be a Wall Street darling, the results could be worth a pretty penny to Yahoo! investors.
