U.S. stocks opened lower on Thursday following disappointing comments from Mario Draghi, the president of the European Central Bank.
At a press conference, Mr. Draghi said the ECB would draw up a mechanism in the coming weeks to make outright purchases to stabilize stressed euro zone borrowing costs. The statement disappointed investors who had been hoping for strong action following his recent comments to "do whatever it takes" to save the euro.
The Dow Jones industrial average was down 56.99 points, or 0.44 per cent, at 12,914.07. The Standard & Poor's 500 Index was down 7.82 points, or 0.57 per cent, at 1,367.32. The Nasdaq Composite Index was down 22.99 points, or 0.79 per cent, at 2,897.22.
"Draghi didn't say anything that excited us, and he set us up like a poker room full of suckers. Investors are angry, traders are angry," said Todd Schoenberger, managing principal at the BlackBay Group in New York.
"Draghi said he would do whatever it takes, and that may be the case, but we were all expecting a shock and awe moment."
European stocks reversed course and turned negative after the statement, with the FTSEurofirst 300 index down 0.9 per cent.
