S&P 500 index slips slightly, posts its first lower week in a month
Shares in US department stores sank again, hurt by more evidence that shoppers are turning away from them.
A drop in Treasury yields also put pressure on bank stocks, and the weakness helped pull the Standard & Poor's 500 index to its first weekly loss in the last four.
The S&P 500 dipped 3.54 points, or 0.1%, to close at 2,390.90, part of a 0.3% loss for the week.
The index is still within half a percent of its record, though, and the market continues to make only modest moves through what's become a weeks-long, peaceful lull.
The Dow Jones industrial average fell 22.81 points, or 0.1%, to 20,896.61, and the Nasdaq composite rose 5.27 points, or 0.1%, to 6,121.23.
Small-company stocks fell more than the rest of the market. The Russell 2000 index lost 7.43 points, or 0.5%, to 1,382.77.
The biggest loss in the S&P 500 came from Nordstrom, which plunged 10.8% to 41.20 US dollars (£32) after it said a key sales figure weakened last quarter by more than analysts expected.
Nordstrom joined a long list of other department store chains that have reported discouraging results recently, as their customers increasingly head online.
JC Penney fell 74 cents after it reported a loss for its latest quarter and weaker revenue than analysts expected.
The broader market, though, was much more pacific. It was the 13th straight day that the S&P 500 moved by less than 0.5%, the longest such streak since 1995.
"It's extremely calm, which always makes us a little nervous," said Eric Marshall, portfolio manager at Hodges Capital Management.
"We're in a very narrow market and a very thin market: It's hard to buy things, and it's hard to sell things because the amount of trading volume out there has slowed down in recent weeks."
The market has grown sleepier as companies have reported stronger-than-expected profits and as encouraging data lifted optimism about the global economy.
The calmness also comes despite a spate of political jolts, including concerns about how successful Republicans in Washington will be at pushing through the pro-business changes that many investors are expecting.
