General Motors headquarters

General Motors stock has been languishing for months, failing to climb past $30 per share since July of last year. Trading at around $22 per share today, the optimism that surrounded the company's emergence from bankruptcy and initial public offering in November 2010 has all but vanished. So it's no wonder that the United States Treasury has decided to sit on its GM shares, with no plans to sell of its remaining 26 percent stake in the automaker.

According to The Detroit News, the Treasury believes that GM is underpriced given the changes that have happened at the company. Assistant Treasury Secretary Time Massad told the News, "Our perspective is that the company has made real progress, but the market hasn't given them as much credit for that as it might."

The government stands to lose $15 billion on the bailout at today's stock prices, according to the report. Of the $49.5 billion spent on the bailout, the government has already recouped roughly $23 billion in reducing its stake in GM from the 61 percent it once held. GM shares would have to more than double in value to $53 for the Treasury to break even in liquidating the 500 million shares it still owns, according to the report.
