Shares of General Motors (NYSE:GM) are up today on the news that the U.S. Treasury Department may sell its remaining 31.1 million shares of the company as early as the end of this year. The government has already sold back over 70 million shares of the company, and says that if the market remains strong it will completely exit its position before 2014. Motley Fool analyst Matt Koppenheffer thinks that, while it's good news that the government is getting its money back, the Treasury Department could've held on a little longer and seen a better return on its investment. Meanwhile this is definitely good news for GM investors, as the company is stronger than it was before the bailout and will be in a better place without government ownership.
