NEW YORK (MarketWatch) -- U.S. stocks ended Monday's session marginally lower, with the S&P 500 and Dow Jones Industrial Average pausing after six straight days of modest gains.

Some analysts said stock markets were overextended after hitting record levels last week. Economic data released on Monday were positive, but not strong enough to lift the mood.

The main benchmarks traded in a narrow range, while the CBOE Vix index remained below 11. The S&P 500 (SPX) closed less than a point lower at 1,962.61. The Dow industrials (DJI) shed 9.82 points, or 0.1%, to 16,937.26. The Nasdaq Composite (RIXF) ended the day less than a point higher at 4,368.68.

Randy Frederick, managing director of trading and derivatives at Charles Schwab, said markets are ripe for a pullback.

"Markets are overbought and are ready for a 3-4% pullback. Last week the S&P 500 hit record levels three times and had 6 up days in a row, while the Vix is at extremely low levels, Frederick said.

"The picture was too rosy and when there is a lot of complacency, market tend to flip," he added.

Craig Callahan, founder and chief executive officer of Denver-based ICON Advisors, said the markets are within 1% of fair value, but the environment for equities is still favorable as earnings are growing, interest rates are low and credit spreads are narrowing.

In economic news, a gauge of economic activity in May from the Chicago Federal Reserve tick up, while a preliminary June reading of business activity from Markit's Purchasing Managers' Index rose to the highest level since May 2010.

Sales of existing homes increased 4.9% in May to a seasonally adjusted annual rate of 4.89 million, the National Association of Realtors reported Monday. A strengthening labor market, expanding inventories and recent drops in mortgage rates supported the second straight monthly increase in sales.

Ahead of U.S. markets, investors received a mixed batch of global PMI reports. HSBC's closely watched preliminary read on the Chinese manufacturing sector swung to growth from contraction, hitting a seven-month high at 50.8. But business activity in the manufacturing and services sectors in the euro zone slowed for a second straight month in June.
