With Microsoft withdrawing its bid, shares of Yahoo! are expected to lose the 50% they have gained since the bid talk. Share of Microsoft, though, are expected to rise.

Without a doubt, the focus of investors this morning is Yahoo (NASDAQ: YHOO) and Microsoft (NASDAQ: MSFT). While Microsoft raised its bid to $33 per share, valuing Yahoo at $46 billion, Yahoo! wanted $37 per share. It is unclear why the two couldn't find common ground at $35 per share. While the heat may very well be on Yahoo! at the moment, with CEO Yang having to prove Yahoo! is better off on its own ... or else, there could be some pressure on CEO Ballmer as well. Initially MSFT stock is expected to rise, but the company still needs to find a solution to its losing internet business. MSFT stocks is up 4.5% in premarket trading to $30.56. YHOO stock is down over 23% to $22.01. To top things off, several analysts have already lowered their rating on Yahoo shares, some even to Sell.
