Stocks closed mostly lower on Wall Street after a day of wobbling back and forth as investors looked over some mixed news on corporate earnings and more in Tuesday’s Stock Market Update.

Health care and energy companies did well Tuesday, but losses in technology and communications companies checked those gains.

Biogen soared 26.1% after the drug company said it would seek federal approval for a medicine to treat early Alzheimer’s disease.

Facebook gave up 3.9%.

Travelers sank 8.2% after the insurance company reported earnings that fell far short of analysts’ forecasts.

This week will be a busy one for investors. Boeing, Caterpillar and Microsoft all report their results on Wednesday. American Airlines, Twitter and Amazon will report on Thursday.


KEEPING SCORE: The S&P 500 fell 10 points, or 0.4%, to 2,995. The Dow Jones Industrial Average fell 39 points, or 0.1%, to 26,788. The Nasdaq fell 58 points, or 0.7%, to 8,104.

HEALTHY STOCK: Biogen soared 26.1% after the biotechnology company gave investors a double dose of good news. The maker of multiple sclerosis and other drugs surprised investors with its move to ask the Food and Drug Administration to approve a potential Alzheimer’s treatment.

The company also handily beat Wall Street’s third-quarter profit and revenue forecasts.
