Regardless of why a stock is in the news, it never hurts to hear what a professional investor has to say about it. The key is to gather as much information as you can in order to make the most informed investment decisions you can. As Jim Cramer often reminds, investors must do their homework.

So what has Cramer had to say lately about today's headline-makers? At Stockpickr, we've combed through his recent RealMoney blog posts, "Mad Money" TV show recaps and "Stop Trading!" segments to find out what he thinks about newsworthy stocks such as Caterpillar ( CAT), Coca-Cola ( KO) and United ( UAUA).

Caterpillar: Excluding layoffs, Caterpillar earned $443 million, or 72 cents a share, in the second quarter, handily beating expectations for 22 cents a share but down 66% from the year-ago quarter's $1.74 per share.
