It's been a tough climb for the investors, and even harder for GM. The re-routed road to success was laced with potholes for the 102-year-old automaker, which was once one of the nation's most valuable companies. After filing for Chapter 11 bankruptcy in 2009, the company was removed from the Dow Jones average, which is comprised of 30 companies. The stock was all but worthless when the government dished out TARP funds.
Despite the bailout by taxpayers, small investors may have a hard time getting the stock at the initial price. There's ownership by the U.S. government, the Canadian government and Chinese involvement in at least two different ways: investment banks in the deal are partly Chinese-owned and there's talk of SAIC, a part of the Shanghai city government, taking an ownership stake, says Aggarwal.
"It's fascinating that three countries are involved with this company," says Aggarwal. "This is the only time this has happened."
The U.S. Treasury will take a loss on its shares in the sale, and can break even only if they climb more than 60 percent, according to analsysis by Bloomberg News.
