General Motors' (NYSE:GM) stock hasn't done well since its post-bankruptcy return to the public markets in 2010. Shares did go up a bit from the General's $33 IPO price, but then they slid sharply, falling below $20 last summer.

Since then, though, GM has put together a nice little rally. In this video, Fool contributor John Rosevear looks at the factors driving GM's recent increase, and at whether this is a blip -- or the beginning of a bull run for America's largest automaker.
