The current economic expansion is one of the longest on record. That's helped to keep the stock market up near all-time highs. But the market isn't always bullish, and investors need to keep an eye out for the downturns that always follow upturns.
Right now, there are some troubling recession warning signs starting to emerge at economically sensitive industrial giants like 3M (NYSE: MMM), Eaton Corporation (NYSE: ETN), and Rockwell Automation (NYSE: ROK). Here's a quick look at what's happening.
Diversified industrial giant 3M is facing a number of worrisome headwinds today. One of the big ones making the news is the company's legal troubles, as it deals with liability surrounding supposedly faulty products and water contamination issues. However, there's a lot more going on today that has investors spooked, sending the shares down by more than a third from their early 2018 highs.
