NEW YORK— U.S. stocks are higher Tuesday as industrial and internet companies rise, and the S&P 500 index is on track for its first three-day winning streak since November.

The latest round of trade talks between the U.S. and China ended without word of progress, but with no evident signs of setbacks either.

Railroad operator Union Pacific jumped after it named an industry veteran to a top executive position. AutoNation fell after predicting a weak year for auto sales.

KEEPING SCORE: The S&P 500 index rose 19 points, or 0.8 percent, to 2,569 as of 2 p.m. Eastern time. The Dow Jones Industrial Average picked up 241 points, or 1 percent, to 23,772. Early in Tuesday’s trading, the Dow jumped as much as 333 points.

The Nasdaq composite gained 62 points, or 0.9 percent, to 6,885. The Russell 2000 index of smaller-company stocks added 17 points, or 1.2 percent, to 1,422.

TRADE TALKS: There was no evidence Tuesday that the U.S. and China made significant progress in their latest round of trade talks, and experts say it will take months for them to resolve the causes of the trade war, which include disagreements over Beijing’s handling of technology and intellectual property. But investors have become notably more optimistic about an eventual deal, a sharp reversal of the concerns that helped send stocks plunging in October and December. An agreement between the two biggest economic powers in the world could remove a major obstacle to global economic growth.

THE QUOTE: Kate Warne, an investment strategist for Edward Jones, said the market’s large moves reflect investors’ questions about major issues including economic growth, the threats of recession and trade tensions, and rising interest rates. She said it’s normal for stocks to change course as traders grapple with those issues on a day-to-day basis.

“You have new information that’s driving stock prices both higher and lower, and that’s pretty typical when there’s uncertainty and there’s a lot of new information coming into the market,” she said.

Warne added that trading on Wall Street is typically light during the holidays, and that can exaggerate market moves up or down.

ALL THE LIVE-LONG DAY: Union Pacific surged 8.3 percent to $150.21 after it hired longtime Canadian National railroad executive Jim Vena as its chief operating officer. Vena will oversee the company’s effort to implement a new scheduling program based on what other railroads including Canadian National have been doing for years.

Other transportation and industrial companies also jumped Tuesday as investors became more optimistic about continued economic growth. Aerospace giant Boeing rose 3.3 percent to $338.97. Among communications companies, Facebook rose 2.7 percent to $141.73 and Verizon added 2.5 percent to $58.16.

ENERGY: Oil prices also continued to rally. U.S. crude it was on track to rise for the eighth day in the last nine and jumped 2.7 percent to $49.83 per barrel in New York. Brent crude, used to price international oils, was up 1.7 percent to $58.33 a barrel in London.

U.S. crude dropped from $76 a barrel in early October to about $42 a barrel on Dec. 24 as investors worried about slowing economic growth and a supply glut. The modest recovery in oil prices has helped energy company stocks after they took big losses at the end of 2018.

CRACKED SCREEN: South Korean smartphone and computer chip maker Samsung said demand for chips is weak because the global economy is slowing. The company expects its fourth-quarter sales to drop 11 percent compared to a year ago and said its operating profit will fall as well. Samsung also said its phones are facing stiffer competition, and its stock fell 1.7 percent in Seoul.

U.S. chipmakers also fell. Nvidia lost 3 percent to $139.14 and Applied Materials dropped 4.2 percent to $36.06.

Tech stocks were roiled on Thursday after Apple said iPhone sales in China were falling.

CHECK ENGINE: Car retailer AutoNation said 2019 will be challenging year for sales, and its stock lost 4.2 percent to $36.06. The company also said it is restructuring its business, and several top executives including its chief operating officer are departing. Used car dealership CarMax gave up 3.7 percent to $63.99 while auto parts retailer AutoZone skidded 1.7 percent to $808.23.

BONDS: Bond prices fell and yields rose, a sign investors expect continued economic growth and higher interest rates. The yield on the 10-year Treasury note rose to 2.71 percent from 2.65 percent late Monday.

Higher interest rates allow banks to make bigger profits on lending, but despite the increase Tuesday, banks stocks declined. Investors may have been preparing for future disappointment: analysts for Goldman Sachs lowered their forecasts for bond yields around the world because of weakening economic growth and tightening financial conditions. The yield on the 10-year Treasury note has fallen sharply since October, when it reached a seven-year high, and the report says yields “may have peaked for this (economic) cycle.”

CURRENCIES: The dollar edged up to 108.62 108.59 yen. The euro fell to $1.1450 from $1.1478 and the British pound slip to $1.2719 from $1.2770.

METALS: Gold fell 0.3 percent to $1,285.90 an ounce and silver dipped 0.3 percent to $15.71 an ounce. Copper rose 0.7 percent to $2.66 a pound.

OVERSEAS: France’s CAC 40 jumped 1.1 percent and Germany’s DAX rose 0.5 percent. Britain’s FTSE 100 rose 0.7 percent.

Japan’s Nikkei 225 index gained 0.8 percent and the Hang Seng in Hong Kong added 0.2 percent. The South Korean Kospi gave up 0.5 percent.
