Viewers who paid attention to yesterday's interview with investor Carl Icahn would've been rewarded. Icahn discussed his stake in WCI ( WCI). But be careful, Jim Cramer said on CNBC's "Stop Trading!" segment Thursday. He reminded viewers that WCI is a small-cap stock with a messy balance sheet but that Icahn has won many more times than he's lost. Cramer also expressed pessimism about the financial sector. " Merrill Lynch ( MER) didn't disclose what it owned. ... At Citigroup ( C), they haven't been able to get the
money they need." More disclosure from Merrill would have helped, Cramer said. "Merrill's disclosure was -- ambiguous," he continued. "I'm being, really, an ambassador." What's more, Cramer said, short squeezes that had been holding the market up are finally giving out. "These have been shorted and shorted and shorted, but the holders have held on. They're not holding on anymore. ... There's panic." Cramer concluded by saying Comcast's ( CMCSA) CEO, Brian Roberts, is being unfairly blamed for the company's declining stock price. Institutional shareholder Chieftain Capital had called for Roberts' ouster in a letter earlier this week. "Every cable company's down big," Cramer said. "I have it on good assurance ... seven days a week he works. ... I think the family that built that company and Brian Roberts have done a wonderful job."
