With many restaurants feeling the benefits of lower gas and energy prices, Action Alerts PLUS director of research Jack Mohr gives his picks of the hottest restaurant stocks. Mohr explains that restaurants that are more focused on natural, fresh ingredients are outperforming -- chains like Chipotle. He also reveals that he likes hamburger chain Jack in the Box, but as shares have risen about 60% in the past six months, he doesn't believe investors should chase it. Mohr predicts that restaurants will pull back at some point, and if Jack in the Box comes down about 10%, he believes that's a good chance to buy. However, he explains why he's also a fan of Panera, which he believes is a buy right here.
