NEW YORK (CNNMoney) -- U.S. stock futures turned sharply lower shortly before the market open Thursday after European Central Bank president Mario Draghi failed to announce concrete plans to help solve Europe's debt crisis.
Investors were left disappointed by the ECB, one day after the Federal Reserve also stopped short of offering a fresh round of stimulus.
U.S. stock futures sank between 0.6% and 0.9% ahead of the opening bell. Earlier, stock futures were up as much as 0.6%.
After the Federal Reserve refrained from taking new action to jumpstart the economy, investors hopes were high that Draghi would announce some form of new action after he pledged last week that the ECB would do "whatever it takes" to preserve the euro.
But Draghi's comments echoed previous remarks, and didn't present any material changes in policy action.
"Once again, we have no commitment to action from the ECB, and no execution of promises previously made," said Carl Weinberg, chief economist at High Freqeuncy Economics. "Nothing seems set to happen now."
Investors have been speculating that the central bank may implement further buying of Italian and Spanish bonds to help stem the region's debt crisis.
Prior to Draghi's strong signals last week that the ECB will act, the Spanish 10-year yield reached a euro-area high of 7.65%, while Italy's 10-year yield hovered above 6%. The borrowing costs in both country's have eased since then, but still remain high.
On Thursday, Spain's government borrowed €3.1 million, more than its target of €3 million, but it had to pay higher interest rates than the prior month. Spain's 10-year sold at an average rate of 6.65%, up from 6.43% in July.
On the domestic front, investors will be taking in reports on job cuts, initial jobless claims and factory orders.
While economic data will be on the backburner relative to any announcement from the ECB, investors will keep close tabs on the labor market ahead of the government's highly-anticipated monthly jobs report due Friday morning.
A CNNMoney survey of economists predicts that the economy added 95,000 jobs in July -- that includes 105,000 job gains in the private sector and 10,000 job losses in the public sector. The unemployment rate is expected to stay at 8.2%.
As expected, the Bank of England held its key interest rate at a record low of 0.5% and left its bond-buying program target unchanged at £375 billion ($585 billion).
Economy: The number of people filing initial unemployment claims rose 8,000 to 365,000 in the latest week, according to the Labor Department, in line with economists' expectations.
Planned jobs cuts fell 45% in July to a 15-month low, according to outplacement firm Challenger, Gray & Christmas.
At 10 a.m. ET, the Census Bureau will release data on June factory orders, which are expected to have increased by 0.6%.
