The following video is part of our "Motley Fool Conversations" series, in which Fool contributor and personal finance analyst Dan Caplinger discusses topics from around the investing world.

Today, Dan looks at Alcoa in the latest installment of a Motley Fool series examining how each Dow stock affects the world-renowned blue chip average. The way that the Dow Jones Industrial Average is calculated makes some stocks almost irrelevant to the average, and Dan explains how even massive moves in Alcoa have very little impact on how the Dow moves. Querying whether the stock belongs in the Dow at all, he also looks at some other stocks that might be better choices for the Dow going forward.

Alcoa is striving to keep its foothold in the world aluminum market, but there are other great businesses that have a lot more potential in capturing the best opportunities in the global economy. To uncover these picks today, we invite you to read a copy of our free report: "3 American Companies Set to Dominate the World."
