"It's just a reversal after a week of one-directional moves," said Jim Paulsen, chief investment strategist at The Leuthold Group in Minneapolis.
Stocks tied to economic growth outperformed more defensive ones last week.
"The news lies ahead in terms of economic reports, in terms of earnings and earnings warnings."

The dollar index, which measures the greenback against six rival currencies, was up 0.45 per cent at 92.36.

Oil prices were little changed on Monday, trading near their highest since May 2015, as political concerns in some OPEC nations offset projections for higher U.S. oil production.
"Oil prices are finely balanced in today's trading session. Ongoing protests in Iran, together with recent detention of several princes in Saudi Arabia, have reinvigorated geopolitical concerns," Abhishek Kumar, Senior Energy Analyst at Interfax Energy's Global Gas Analytics in London.
"However, prospects for further increases in U.S. oil production amid recent improvements seen in oil prices continue to promote bearish sentiment," Kumar said.
Brent futures gained 16 cents, or 0.2 per cent, to settle at $67.78 a barrel, while U.S. West Texas Intermediate (WTI) crude rose 29 cents, or 0.5 per cent, to settle at $61.73.
Last week, both contracts rose to their highest since May 2015 with Brent at $68.27 and WTI at $62.21.
U.S. production is expected soon to rise above 10 million barrels per day, largely thanks to soaring output from shale drillers, according to federal energy data.
Only Russia and Saudi Arabia produce more.
"The U.S. oil price is now into a range that is anticipated to attract increased shale oil production," said Ric Spooner, chief market analyst at CMC Markets in Sydney.
"Traders may decide that discretion is the better part of valor while markets wait on evidence of what happens to the rig count and production levels over the next couple of months," Spooner said.
