(Image credit: Mario Tama/Getty Images) When Elon Musk took Tesla ( TSLA ) to market in June 2010, the electric vehicle maker raised more than $226 million in its initial public offering (IPO). That pales in comparison to General Motors ( GM ), which raised roughly $20 billion in its November 2010 offering, when the automaker returned to the public markets after filing for Chapter 11 bankruptcy in 2009. Tesla has grown into a trillion-dollar company and the biggest U.S. automaker by market capitalization. The stock has also averaged an annual return of 42.6% since it began trading, outpacing the broader S&P 500 by 31.7 percentage points.
