Yahoo!'s (YHOO) '100-day review' nears end: Are investors still patient?

When Yahoo (NASDAQ: YHOO) co-founder Jerry Yang returned to the CEO role this past summer, he gave investors and watching employees a "100-day review" speech that basically gave Yang time to study, assess and form solutions on getting the internet behemoth back on track for higher growth levels and ensuring it wasn't losing ad revenue to the competition.

Well, that 100 days is now nearly over with, and even the few acquisitions (BlueLithium and Zimbra) that Yahoo! has made recently have not quenched the irrational desire of analysts who aren't satisfied until immediate results happen. This is, of course, so unrealistic it's laughable. Any analyst should know drastic changes take time to work, aside from massive layoffs that can immediately affect a company's finances. This is not the case with Yahoo!, which is trying desperately to keep up with competitor Google (NASDAQ: GOOG) in the space for online advertising.

Although Yang has professed that nothing within the company is a "sacred cow," industry watchers may be already impatient in waiting for the company to somehow reinvent its business to capture more growth that Google appears to be hauling in by the truckload at the moment. Nothing so far looks like the "radical surgery" that many pundits probably thought would happen, and with Google set to deliver Q3 results this Thursday, the pressure cooker may become even more intense soon.
