Jim Cramer says the bear market is keeping some good stocks in check, and explains why Alcoa (AA) didn’t jump much higher on news of its split, and why Williams (WMB) stock fell after its nearly $38 billion acquisition by Energy Transfer Equity (ETE). Cramer made those comments while answering viewers’ Twitter questions on the floor of the New York Stock Exchange Monday. Cramer said many companies are doing good things, but their stocks are still going down in this current market environment. In the case of energy, Cramer said those stocks remain in a bear market. He also said investors should question whether some companies, like Magnum Hunter Resources (MHR) and SandRidge Energy (SD), can survive the downturn. Cramer said he turned very negative on oil and natural gas, and that Action Alerts PLUS doesn't have a big exposure to the sector. 'The charitable trust owns Energy Transfer Partners (ETP). The stock's been cut in half, it's got a huge yield, nobody cares, again, because we're in a bear market for energy.' Cramer also discussed Carl Icahn's share purchases of Chesapeake Energy (CHK) and Freeport-McMoRan (FCX), saying he doesn't like either stock, but agrees with Icahn's purchases of Cheniere (LNG) stock.
