Sunnyvale, Calif.-based Yahoo owns a 24 percent stake in Hangzhou, China-based Alibaba. The Chinese e-commerce company is expected to file its initial documents for a public offering sometime early this week, which will help shed light on its value and how the tech giant's worth is being calculated.
The filing also will help Yahoo's stock price, said Larry Levine, managing director in McGladrey LLP's Financial Advisory practice.
"From a U.S. perspective, Yahoo has the most to gain. Alibaba disclosing its financial data will give Yahoo's stock more stability," Levine said. "It's very difficult to value it with information that we have right now, the price range is very wide...so I would expect that Yahoo's stock price reflects all that volatility."
