General Motors stock holds unrealized value for investors, Steven Rattner of Willett Advisors said Tuesday on CNBC.
"I think you have to look at everything as a price to value, not just who has the best products or who might be best positioned but whose stock is also the best value," he said. "And I think there is still an unnatural and inappropriate overhang over General Motors stock relative to its value."
On "Fast Money," the former auto industry advisor to the Treasury Department under President Barack Obama said that the stock should be trading higher.
"It trades at a significant discount to Ford. I don't think that's warranted," he said. "I think GM is a great company. It has some things to prove over the next few months with its next product launches. But if you want to look for a great company with a stock that I believe is undervalued, that's where I would be looking."
"I think you stay away from the makers," he said. "I think you go downstream."
EmergingMoney.com's Tim Seymour saw strength in Chrysler, especially since its focus on producing muscle cars once again.
"Take a look at Fiat because this company's cheap," he said.
