According to Deutsche Bank, Opel has experienced a 30 percent year-over-year drop in production -– a loss that has been imposing upon North American profits. Deutsche Bank analysts believe that General Motors' true value will not be known for months. With additional scrutiny from the weekend recall announcement, it is no wonder that the automaker is down slightly on Monday. "The next 3 months should determine if GM is a good value or a value trap. GM shares are down &LT3% YTD, but it feels far worse. GM remains a cheap stock at 6x PE and 2x EBITDA with optionality to reviving product, improving costs and removing Europe. But this story requires a degree of market confidence the economy is not providing, and a degree of visibility that management is also simply not providing, leaving investors wondering if it's too early to buy the stock," Deutsche Bank recently said. General Motors closed Friday at $22.01, up over 8.5 percent year-to-date.
