In this video, Motley Fool analyst Taylor Muckerman outlines three reasons to buy Alcoa (AA). First, there is a rebound in the global economy, particularly in China and, to a lesser extent, the United States. Demand for aircraft, autos, and truck trailers are projected to drive aluminum demand. Second, Alcoa is actively restructuring its business and pursuing other means of reducing its costs. Lastly, Alcoa is set on maintaining its investor grade credit rating which means that it can expand its business through the debt market at attractive rates if it chooses.
