Stocks struggle as markets remain volatile; oil drops

U.S. stocks remained volatile Monday as the market took a dive in early trading only to erase those losses later and end slightly higher.

The Dow Jones Industrial Average lost as much as 507 points in early trading before ending with a gain of 34.

Energy companies fell as the price of crude oil dropped 3 percent, giving back its gains from last week. Banks fell as investors expected slower increases in interest rates.

Technology companies led the gainers. Qualcomm rose after the chipmaker said a Chinese court banned some Apple phones as part of a long-running dispute over patents.

Weak economic data in China and Japan and uncertainty over Britain’s status in the European Union knocked down overseas indexes. The British pound dropped to its lowest level in more 18 months after Prime Minister Theresa May postponed a vote on the country’s departure from the European Union.

Tensions between the U.S. and China kept climbing following the detention of Huawei Chief Financial Officer Meng Wanzhou. She is suspected of trying to evade U.S. trade curbs on Iran, and she was detained while changing planes in Canada.

China summoned both the U.S. and Canadian ambassadors to meetings over the weekend and protested her arrest. Meng’s arrest has jolted the stock market.

“It’s a source of great anger for China that this could happen,” said Kristina Hooper, chief global market strategist for Invesco. “China is looking for retaliation, and the most appropriate place for retaliation would be in trade negotiations with the U.S.”

The S&P 500 index gained 4.64 points, or 0.2 percent, to 2,637.72. The Dow added 34.31 points, or 0.1 percent, to 24,423.26. Technology companies, which have fallen sharply since October, did better. The Nasdaq composite rose 51.27 points, or 0.7 percent, to 7,020.52.

The Russell 2000 index of smaller-company stocks dipped 4.99 points, or 0.3 percent, to 1,443.09.
