NEW YORK (TheStreet) -- U.S. investors cheered an agreement between Greece and its European creditors following months of back-and-forth deliberations.
The development triggered a relief rally, helping Wall Street to close out its best three days since March.
The S&P 500 rose 1.1%, the Dow Jones Industrial Average gained 1.2%, and the Nasdaq was up 1.5%.
European leaders agreed to a bailout of 86 billion euros ($95 billion) for Greece, though the country must impose strict spending cuts in exchange for the additional funds. The deal helps prevent Greece from exiting the eurozone, an unprecedented and potentially catastrophic outcome for the region.
"It's much better than anyone really expected," Kathleen Brooks, head of research at City Index, told TheStreet. "We were getting into a really desperate situation. By next Monday ... Greece had to repay the ECB 3.5 billion euros. It didn't have the money to do that so it has avoided another default. This has been certainly the best outcome and avoids that near-term default which would definitely have meant the collapse of the Greek banking sector."
The Greek chapter hasn't been closed yet, though, with the country's parliament still to vote on the deal's terms on Wednesday.
"There are still a variety of details to be agreed upon after the fact," wrote CRT Capital's David Ader and Ian Lyngen in a note. "Greek banks are still closed and the July 20 ECB payment of 4.2 billion euros looms ... We're apprehensive that although ostensibly a compromise has been reached, the market remains vulnerable to headlines related to the ultimate completion of the deal."
