Auto sales in the U.S. have been rising steadily for over a year now. That has been a good sign for a recovering economy, and great news for automakers like Ford (F -2.19%), which has banked huge profits on very strong U.S. sales.

In this video, Fool contributor John Rosevear explains what's behind the prediction, and why Ford might be one of the very few automakers to post a gain when this rough month ends.
