Stocks ended with a whimper Monday, after hitting record highs once again last week.
On a quiet week for economic and earnings data, Monday's dip seems more related to gravity (what goes up must come down) than anything specific.
The one piece of data out Monday didn't move markets: The Institute for Supply Management's monthly service-sector index came in above expectations.
Looking at stocks on the move, Tyson Foods ( was one of the biggest gainers in the S&P 500 after the meat processor reported better-than-expected earnings. )
HSBC ( shares dropped after the company reported results for the first half of the year that disappointed investors. The company announced an increase in revenue and profit before tax over the previous year as it sold assets. )
Tech stocks stay in focus: Apple's ( stock rose modestly, after the Obama administration vetoed an International Trade Commission )import ban on some of its products.
