Yahoo may not be operating on "Internet time" when it comes to its turnaround plan, but the clock is still ticking for the popular Web portal. CEO Terry Semel bought the company precious time earlier this month when he announced a restructuring strategy to investors, highlighting a plan to make the company less dependent on fickle advertising dollars by 2004. Yahoo stock shot up as much as 20 percent after the proposal was presented Nov. 15, although it has fallen back in the past few days. Nevertheless, some question whether investors will wait out a three-year plan without some interim signs of recovery. "Six more months and we've got to see more results," said Safa Rashtchy, an analyst for U.S. Bancorp Piper Jaffray. "Our expectations are low now, so (Semel) can actually over-deliver." Few expect Yahoo to bounce back as suddenly as it fell: Last year, the Web portal posted record revenue of $1.1 billion, a figure that will drop to about $700 million this year, according to estimates.
