( YUM) for his Action Alerts PLUS charitable trust. He also likes Panera ( PNRA), but it's up $3, so he recommended waiting to buy. ConAgra ( CAG) "is not done going up," he said. He called its quarter "really beautiful" and said that CEO Gary Rodkin is an "extraordinary manager." Outside of food stocks, he also likes Whirlpool ( WHR). "Everyone thought it was a short squeeze," he said, until Best Buy ( BBY) posted an earnings beat.
