Activist investor Carl Icahn is calling for eBay to spin-off its PayPal unit in a move to unlock shareholder value. For it's part, eBay says it is not interested in breaking up the company. TheStreet's Jim Cramer believes if Icahn is successful, shares of eBay could move higher. But, if Icahn fails, Cramer says the shares could move lower. Stifel Nicolaus analyst Jordan Rohan thinks shares are now fairly valued and lowered his rating on eBay from a BUY to a HOLD. TheStreet's Ruben Ramirez has more from Wall Street.
