Jim Cramer told fans of CNBC’s “Stop Trading!” show to avoid trading the potential Tropical Storm Gustav. Cramer doesn’t think it’s smart to play natural gas and oil companies off the storm, because if it doesn’t hit oil could fall $8 to $9 by Tuesday. Next, Cramer brought up a recent story from The Wall Street Journal that said the infrastructure trade is dead. Cramer took issue with the call and said if the trade is dead why is Fluor (FLR) up so big and why is Shaw Group (SGR) and Foster Wheeler (FWLT) moving higher. Moving on, Cramer said he wants to know who the source was for the Barron’s article that caused Freddie Mac (FRE) and Fannie Mae (FNM) to fall 50%. “All that’s happened is that it’s gotten worse for Fannie and Freddie, but the stocks go up every day. Where is that Barron’s source,” Cramer asked. Finally, Cramer told viewers he is buying Quanta Services (PWR) for his charitable trust. He said PWR is solving the problem of connecting alternative energy sources to the energy grid. Chat and share ideas with the best small cap traders LIVE each day free at Stocknetworkonline.com
