The following video is part of our "Motley Fool Conversations" series, in which industrials editor/analyst Brendan Byrnes discusses topics across the investing world.

In today's edition, Brendan gives his opinion on whether Caterpillar is a buy, a sell, or a hold. The construction equipment giant was once the second-best performer on the Dow early in 2012, but it has fallen hard recently due to concerns about Europe and the macro economy. Brendan thinks Caterpillar is extremely attractive at its current price, and he rates the company as a buy. Caterpillar should continue to benefit from robust mining growth, especially after its acquisition of Bucyrus last year. Additionally, the company continues to be an innovator and is looking dirt cheap trading at just eight times forward earnings. Check out the video below for more reasons why Brendan rates Caterpillar as a buy.
