General Motors (NYSE:GM) this week opened a new stamping plant in Arlington, Texas. The plant, which makes parts for GM's SUVs, cost $200 million to build and added over 100 new jobs. That's certainly important to the local economy -- but why is it important to investors in GM stock?

It's not obvious from the headlines, but this new factory is just the latest move by GM in a strategic global plan that the auto giant is using to quietly boost its profits. In this video, Fool.com contributor John Rosevear explains why the new factory is important -- and how it, and others like it, could give GM's stock a big boost over time.
