It's time to "blow out" of speculative stocks like Hoku ( HOKU) in the runup to President Bush's speech tonight, Jim Cramer said Tuesday on CNBC's "Stop Trading!" segment. Cramer said Hoku, the Hawaii-based supplier of material for solar panels that has come into vogue since it scored a supply deal last week with Sanyo, is "trading more than its float" every day -- a signal that the action may not be based purely on the stock's fundamentals. On Tuesday, shares were up 11% in heavy trading as some investors were betting that the president's energy conservation proposals would play to Hoku's favor. "People are trying to game a speech that isn't gameable," Cramer said of the president's State of the Union address, which is scheduled for 9 p.m. EST. Cramer also called the ethanol trade "baloney" but said that if he really believed in renewable power talk, he might try Archer Daniels ( ADM).
