"The market has gotten way too negative," Jim Cramer told viewers of his "Mad Money" TV show Tuesday. "The market took down a lot of good stocks that don't have anything to do with the economy, consumer spending or Fed chairman Ben Bernanke," he said. "Pull the trigger and just buy something." Cramer still sees bull markets in agriculture, defense, mining and minerals, oil and natural gas and healthcare cost containment stocks. He reiterated his buys on natural gas driller Chesapeake Energy ( CHK) and Agnico-Eagle Mines ( AEM) in the gold sector.
