But what's ahead for shares of the struggling equipment-manufacturer? In the video below, Fool contributor Demitrios Kalogeropoulos tries to answer that question by first taking a look at Caterpillar's recent business results.

He notes that this year's weakness has been driven by plunging demand in the mining industry, and the outlook for that business heading into 2014 doesn't look good. Meanwhile, as current shareholders will continue to benefit from Caterpillar's impressive cash-generation and capital-return policies, Demitrios says he wouldn't be a buyer of the stock until the mining sector shows some signs of a recovery.
