That was clearly illustrated by Deere & Co and Staples which both posted quarterly results that fell short of expectations. Shares of Deere were last 5.9 per cent weaker, while those of Staples shed 15.1 per cent.
Staples lowered its full-year outlook for profit and sales, citing slower growth in the US and weakness in Europe.
"The weakness in Europe was not a surprise, but the deterioration in the US was more significant than anticipated," Janney Capital Markets analyst David Strasser told Reuters.
To be sure, Abercrombie & Fitch's quarterly profit surpassed estimates. The stock was last up 9.1 per cent. Shares of Target also advanced, last up 1.9 per cent, after the company lifted its annual profit forecast.
Indeed, some took the recent US economic data as an indication that the Federal Reserve is less likely to increase its monetary stimulus soon. US Treasuries declined, lifting 10-year yields toward the highest level in nearly three months.
"We definitely have seen some better economic numbers and it's put a dent in QE3 expectations," Thomas Roth, senior Treasury trader in New York at Mitsubishi UFJ Securities USA, told Bloomberg. "The market's at risk for the first time in a long time."
Meanwhile, yields on German 10-year bunds rose after Bloomberg reported that European Economic and Monetary Affairs Commissioner Olli Rehn signalled Spain is weighing a request for a sovereign bailout.
"The Spanish government has an open mind on this issue, but no decision has been made" on whether to request a bailout, Rehn told Bloomberg yesterday. "We stand ready to act if there is a request."
Europe's Stoxx 600 Index edged 0.1 per cent lower from yesterday's close. Benchmark stock indexes in Germany, the UK and France declined as well.
