>> US stocks off to a rough start Tuesday with the Dow at one point falling more than 500 points after US corporate earnings disappointed investors. Industrial giant Caterpillar's stock plunged as much as 8% the most since 2015, after it warned about future profits, putting the blame on US tariffs for rise in costs.
Also, 3M missed expectations with sales in China cooling off sending shares down 5%. Overnight in Asia, investors dumped stocks as well giving back some of the gains made after the region saw a two-day rally. And in Europe, the main stock market index slipped towards its lowest level since December 2016.
All three US indexes remained in the red Tuesday, continuing what has been a punishing month for US stocks.
