Greece and euro zone finance ministers reached deal on Friday to extend the Greek bailout by four months.
"This obviously is a relief for the markets," said Peter Cardillo, chief market economist at Rockwell Global Capital. "Looks like my 2,125, 2,150 (on the S&P 500) likely to be achieved early next week. (We have) light volume but we're at record highs."
"Looks like the agreement ... was already "baked" into the market. Not much of a surprise here," said Lance Roberts, general partner at STA Wealth Management. "The real issue is that this agreement only gets them to the nextbig debt maturity which puts them back at this all over again. A kick the can down the road for now."
The U.S. 10-year Treasury yield rose to trade near 2.13 percent on the Greece news.
"Obviously (we) see safe haven money exit the bond market (and) come flying into stocks," Cardillo said.

The Eurogroup of regional finance ministers was expected to make an announcement on Greece's loan extension proposal on Friday. Germany rejected the plan on Thursday and called it a "Trojan horse" with "immense room for interpretation."

Deere said it earned $1.12 per share for its latest quarter, well above the 83 cent consensus estimate, with revenue also beating forecasts. However, the farm machinery manufacturer highlighted difficult global market conditions and said it expected a 17-percent drop in equipment sales for 2015.
The outlook cut is "a global macro call," Hogan said. "It's really Brazil. If you think about John Deere and Caterpillar, they're global players."
Barclays downgraded Wal-Mart to "equal weight" from "overweight," saying the retailer is unlikely to see near-term benefits from its just-announced increase in wages that offset the higher expenses.
Newmont Mining earned an adjusted 17 cents per share for its latest quarter, 7 cents above estimates, with its revenue also beating forecasts. Newmont said its "growth projects" are doing particularly well.
The Noodles restaurant chain missed estimates by a penny with adjusted quarterly profit of 13 cents per share, with revenue falling just below estimates as well. It also cut its full-year guidance, as same-restaurant sales growth fails to meet prior forecasts.
