Yahoo (YHOO) shares surged more than 10 percent to a new five-year high on Wednesday, as investors ignored the Sunnyvale Web portal's struggling business and cheered the strong performance of its investment in Alibaba Group.
The Chinese e-commerce giant, in which Yahoo owns a 24 percent stake, nearly tripled its net income in the first three months of the year and increased its revenue by 71 percent.
Yahoo did not provide any details about what was responsible for the strong performance of the privately-held Alibaba Group, which is widely expected to have a public offering later this year or in 2014.
Yahoo's earnings report includes Alibaba's financial results from the previous quarter. Alibaba's first-quarter results stood in sharp contrast to Yahoo's own performance during the second quarter, with the Web portal reporting stagnant revenue and a sharp decline in prices for its display ads.
Wall Street's focus on Alibaba rather than on Yahoo was reflected in the slew of analyst notes published following Yahoo's earnings, including Stifel Nicolaus' Jordan Rohan whose note to investors was titled: "Alibaba triples profit; Yahoo reported too."
"We continue to think that the defining factor for Yahoo stock is the value of Alibaba," Bernstein Research analyst Carlos Kirjner said in a note.
Shares of Yahoo gained 10.4 percent to $29.67 Wednesday, hitting an intraday high of $29.73.
Yahoo's stock has surged more than 85 percent since CEO Marissa Mayer took the reins one year ago. Much of the gains have been due to aggressive stock buybacks funded by Yahoo's earlier sale of a portion of its Alibaba stake, as well as anticipation of an Alibaba initial public offering.
At least four brokerages raised their valuation on Alibaba to as much as $120 billion, higher than the $100 billion valuation put on Facebook before its IPO. Yahoo has a market capitalization of about $29 billion.
Evercore, which raised its valuation on Alibaba to $120 billion from $90 billion, said nearly half of Yahoo's valuation is due to its stake in the Chinese company and only a quarter can be attributed to its core business.
Yahoo acquired a 40 percent stake in Alibaba in 2005 for $1 billion, in a deal arranged by Yahoo co-founder Jerry Yang, which has proved to be one of the company's shrewdest investments.
Yahoo's second-quarter results underscored the challenges CEO Mayer faces as she tries to revive the company's core business, which has suffered from competition from Google (GOOG), Facebook and other online services.
Yahoo trimmed its full-year revenue forecast to $4.45-$4.55 billion from $4.5-$4.6 billion. Revenue fell slightly in the second quarter to $1.07 billion.
"For most, the Yahoo story will not change given strength in Asian assets," said JPMorgan analyst Doug Anmuth, "but core Yahoo challenges serve as a reminder that turning Yahoo into even a modest growth business will likely take some time."
