TheStreet’s Action Alerts PLUS Portfolio Manager and host of CNBC’s ‘Mad Money’ Jim Cramer commented on Caterpillar's (CAT) earnings report when answering viewers questions from social media on Thursday. Cramer said while Caterpillar's balance sheet has been fixed, the company has some difficult end markets such as oil, mining and construction. He added that Caterpillar is also levered to China. Still, Cramer said he thinks the dividend is safe, thanks to the balance sheet. Another viewer asked about stock of Nucor (NUE) ahead of its earnings. Cramer responded that it's the only steel company he would get in front of, with the exception of Reliance Steel (RS), but Cramer added the company is being eviscerated by Chinese dumping, something he'll be talking about more next week. Cramer was asked about Under Armour (UA), and he responded that investors should look at the growth of the company's Connected Fitness business, which is fantastic. He said if the stock comes in, buy it. McDonald's (MCD) was the subject of a viewer question. Cramer spoke highly of McDonald's CEO, calling Steve Easterbrook 'magnificent' and said the turn is real. On a side note, Cramer also said his favorite meal is an Egg McMuffin. You can send Jim Cramer questions on Facebook, and on Twitter, follow him @JimCramer and send questions using #CramerQ.
