NEW YORK (CNNMoney) -- Hope for a real solution to Europe's ailing economy lifted U.S. stocks Thursday, after European Central Bank president Mario Draghi said the central bank would do whatever it takes to preserve the euro.
Speaking at an investment conference in London,Draghi's comments suggest the ECB may start buying bonds again in an effort to help bring down skyrocketing borrowing costs.
"His comments were a bit of a game changer because they put the power back in the ECB to buy Spanish and Italian bonds," said Paul Zemsky, chief investment officer for ING Investment Management. "That caused a great turnaround in sentiment."
Analysts also said Draghi's comments signify that another long-term refinancing operation -- the ECB's cheap lending program aimed at preventing a credit crunch -- is back on the table.
But some analysts caution that this initial excitement may wear off, since Draghi didn't definitively outline new measures.
"This wasn't exactly a plan. It was a statement," said Kim Caughey Forest, senior equity analyst for Fort Pitt Capital Group. "It's more words, not a whole lot of action."
The country's borrowing costs remain unsustainably high, with Spain's 10-year yield hovering near 7%, after touching an all-time high of 7.75% Wednesday.
And with bailouts on the table for both Spain and Italy, investors are worried about the odds of a Greek exit. Citigroup analysts said there's a 90% chance that Greece will leave the euro currency in the next 12 to 18 months, since the new government hasn't been able to effectively put an austerity plan in place.
While Draghi was driving Thursday's rally, investors also had a fresh batch of corporate earnings to contend with, with the most anticipated numbers of the day coming after the close, when Facebook (quarterly results as a public company.) reports its first set of
