GM Shares Close at Post-IPO Record as EV Plans Draw Praise

General Motors Co. Chief Executive Officer Mary Barra is finally delivering the share-price gains that have eluded an otherwise successful seven-year run atop the Detroit automaker as investors give her electric-vehicle plans credibility.

The stock closed at a record $47.82 a share Tuesday -- 45% above its post-bankruptcy initial public offering price of $33 in November 2010 and up about 15% this year -- after the company detailed an expanded push into electric vehicles with new luxury and commercial models.
