REUTERS - The Nasdaq composite edged up on Thursday after two days of losses, while the S&P 500 and Dow were lower on weak earnings from bellwethers such as 3M and Caterpillar .
The two stocks, together with American Express , contributed 104 points to Dow's fall.
Caterpillar shares fell as much as 3.4 percent to a four-year low of $77.03 after the world's largest construction and mining equipment maker reported sales decline in key markets in a sluggish global economy.
American Express fell 2.9 percent to $77.66 as revenue missed expectations while 3M was down 2.3 percent at $151.72 after the diversified manufacturer cut its full-year forecasts.
"Companies such as Caterpillar are a litmus test for the global economy especially when the market is concerned about China's economy," said Mark Luschini, chief investment strategist at Janney Montgomery Scott in Philadelphia.
