U.S. stocks close up, lifted by oil prices and Apple

U.S. stocks rose Monday as crude oil jumped to its highest price in more than a year and energy companies climbed with it. Investors also reacted to the latest twists in the presidential race.

Apple reached its highest price of the year and led tech stocks higher after new reports of fires affecting Samsung’s Galaxy Note 7 phone, which competes with Apple’s iPhone.

Steve Chiavarone, an associated portfolio manager for Federated Investors, said a tumultuous weekend for Republican candidate Donald Trump contributed to the market’s gains. He said investors mostly expect Democratic candidate Hillary Clinton to win, and that they are concerned about the effect Trump’s trade proposals would have on the market and the economy.

“What you’re seeing in the market is a cheering of the status quo,” he said. In his view, that’s because investors understand Clinton’s views and what her administration might look like even though they may disagree with her on issues such as tax policy.

The Dow Jones industrial average climbed 88.55 points, or 0.4%, to 18,329.04. The index had been up as much as 159 points earlier in the day. The Standard & Poor’s 500 index rose 9.92 points, or 0.5%, to 2,163.66. The Nasdaq composite advanced 36.27 points, or 0.7%, to 5,328.67.

Apple climbed 1.7% to $116.05 on investors’ hopes that the company will be able to sell more iPhones as competitor Samsung faces new problems with its Galaxy Note 7. Samsung said it has changed its production of the phones following reports that some of its replacement phones are overheating and catching fire, just as the original version of the phone did before Samsung recalled it last month. Samsung did not confirm or deny a report from a Korean news agency that it suspended production of the Note 7 phone.

Mylan jumped 8.2% to $38.87. On Friday the drugmaker agreed to pay $465 million to settle allegations it overcharged the Medicaid program for its EpiPen allergy shot. Legislators and federal health authorities had said Mylan wrongly classified EpiPen as a generic drug instead of a brand-name one, which meant Mylan paid lower rebates to federal and state Medicaid programs. The stock is down 20% since late August.

Bristol-Myers Squibb plunged again, falling 10.1% to $49.81, after the company reported more data from a study of its drug Opdivo in lung cancer patients. Rival Merck rose 1.8% to $63.90 as investors were pleased with results from a study of its cancer treatment Keytruda. Bristol-Myers stock has dropped 34% since the company announced initial results from its Opdivo trial in early August, sending the price to almost two-year lows. Merck is up 10% over the same time.

The Mexican peso grew stronger after Trump’s calamitous weekend. Trump has criticized Mexico and its trade agreements with the United States, so the peso has become something of an indicator of how investors feel about the election. The currency has tended to weaken when investors feel Trump is doing better and gets stronger when investors feel more confident in Clinton’s chances. The United States buys about 80% of Mexico’s exports, giving it a big influence on the Mexican economy.

After the peso’s surge Monday, one U.S. dollar bought just 18.92 pesos, versus the 19.26 pesos it bought Friday. The peso has weakened sharply this year but is currently the strongest it’s been in about a month.
