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

Today, Dan looks at ExxonMobil in the latest installment of a Motley Fool series in which we examine how each Dow stock affects the world-renowned blue chip average. Even though Exxon has the biggest market cap of any Dow component, the way that the Dow Jones is calculated gives Exxon less weight than several other stocks in the Dow. Dan discusses whether this fairly reflects Exxon's influence and then speculates about whether more energy stocks might get added to the Dow in the future.

From Exxon on down, energy stocks present a huge potential for growth and profits. Let me invite you to read about one promising energy stock right here in The Motley Fool's special free report on the energy industry and its best prospects.
