Yahoo! endured a difficult month, with disappointing results and changes in the executive ranks. Its stock dropped sharply after it warned first-quarter results would miss its forecast because its business from non-Internet companies produced less revenue than expected. Merrill Lynch analyst Henry Blodgett speculated Yahoo! would announce a merger; instead, CEO Tim Koogle said last month he would step down, but remain as chairman. The stock rebounded a bit, but analysts remain reluctant to recommend it until the price stabilizes.
