Euro-zone finance ministers will meet to approve a 130 billion euro rescue package for Greece on Monday when the US market will be closed for the Presidents Day holiday.

"The fact the European market is up the Friday before, knowing the US market is off on Monday, is really a sign that the Greece situation is priced into the market," said Andrew Slimmon, managing director of Global Investment Solutions at Morgan Stanley Smith Barney in Chicago.

Analysts were wary of a pullback after Thursday's strong gains pushed the S&P to its highest since May 2 and viewed the market's resilience as constructive.

"It is encouraging that we obviously had some breakouts yesterday on the indexes and we are not giving anything back," said Ryan Detrick, senior technical strategist at Schaeffer's Investment Research in Cincinnati.

Technicians see the market at a short-term top, with the S&P at nine-month highs and within 10 points of hitting its highest level since 2008.

For the week, the Dow rose 1.2%, the S&P gained 1.4% and the Nasdaq advanced 1.7%.

Equity markets have tended to react positively on progress toward helping Greece avert a disorderly default, but past agreements have broken down at the last minute.
