The major U.S. stock indexes veered slightly lower in afternoon trading Friday, adding to the market’s modest losses from a day earlier. Technology companies led the slide. Phone companies and airlines were among the biggest gainers. A new round of tensions between the U.S. and North Korea helped send bond yields lower, which weighed on bank shares.

KEEPING SCORE

The Standard & Poor’s 500 index slipped 1 point, or 0.1 percent, to 2,499 as of 8:09 a.m. The Dow Jones industrial average shed 28 points, or 0.1 percent, to 22,331. The Nasdaq composite slid 3 points, or 0.1 percent, to 6,418. The Russell 2000 index of smaller-company stocks added 6 points, or 0.5 percent, to 1,450.

NORTH KOREA

Geopolitical tensions ratcheted up after President Donald Trump authorized stiffer sanctions in response to North Korea’s nuclear weapons advances, drawing a furious response from Pyongyang. Trump expanded the Treasury Department’s ability to target anyone conducting significant trade in goods, services or technology with North Korea, and to ban them from interacting with the U.S. financial system. North Korean leader Kim Jong Un retaliated by calling Trump “deranged” and saying he’ll “pay dearly” for his threats.

THE QUOTE

The small moves in U.S. stock indexes suggested investors were shrugging off the latest wave of ramped-up tensions between the U.S. and North Korea, said Erik Davidson, chief investment officer for Wells Fargo Private Bank. He also noted that the VIX, a measure of how much volatility investors expect in stocks, also was little changed.

“Overnight markets had a little bit of weakness based on the North Korea situation, but that has not extended into the U.S. markets today,” he said. “The North Korea news has contributed to bonds’ strength, but it’s interesting that we have not had a commensurate weakness in equities.”

BOND MARKET

Bond prices rose. The yield on the 10-year Treasury slipped to 2.26 percent from 2.28 percent on Sept. 21. The decline weighed on bank shares, including U.S. Bancorp, which was down 34 cents, or 0.6 percent, to $53.40. Lower bond yields mean banks have to charge lower interest rates on long-term loans like mortgages.

FEELING BETTER

Several health care companies recovered some of the ground they lost earlier as Sen. John McCain said he won’t vote for the latest Republican bill to repeal the Obama health care law. His statement likely deals a fatal blow to the last-gasp GOP measure in a Senate showdown expected next week. UnitedHealth Group, the nation’s largest health insurer, was down 51 cents, or 0.3 percent, to $194.70. It traded as low as $188 earlier. Centene, which administers Medicaid programs and sells health plans to the Affordable Care Act’s exchanges, rose $3.04, or 3.4 percent, to $93.78. Molina Healthcare gained $3.04, or 4.9 percent, to $65.55.

TECH SLIDE

Technology sector stocks also weighed on the market. Apple was down $2, or 1.3 percent, to $151.39. Advanced Micro Devices fell 17 cents, or 1.3 percent, to $13.24.

HIGH FLYERS

Industrials sectors stocks, including several airlines, were among the biggest gainers. Alaska Air Group added $1.72, or 2.4 percent, to $74.63. American Airlines Group rose $1.03, or 2.2 percent, to $47.32.

ROCKY OUTLOOK

Compass Minerals slid 10.8 percent after the mining company cut its annual profit forecast after a partial ceiling cave-in at a rock salt mine in Ontario that will slow operations for six weeks. The stock was down $7.48 to $62.03.

DIAL-A-DEAL

Sprint climbed 4.7 percent after Reuters reported the wireless carrier is close to signing a deal with rival T-Mobile. Shares in Sprint added 38 cents to $8.41. T-Mobile gained 51 cents, or 0.8 percent, to $63.90.

IN GEAR

CarMax rose 7.8 percent after the used car retailer’s latest quarterly results beat analysts’ forecasts. The stock gained $5.35 to $74.19.

ENERGY

Benchmark U.S. crude was down 4 cents to $50.51 a barrel on the New York Mercantile Exchange, giving up an earlier gain. Brent crude, used to price international oils, added 21 cents to $56.30 a barrel in London.

CURRENCIES

The dollar weakened to 112.07 yen from 112.55 yen on Thursday. The euro climbed to $1.1947 from $1.1934.
