NEW YORK (AP) -- A handful of deals helped nudge the stock market up in early trading Monday, despite a disappointing report on the economy.
Amgen surged 8 percent, the biggest gain in the Standard & Poor's 500 index, after the biotech giant said it plans to buy Onyx Pharmaceuticals for $10.4 billion. The deal, announced late Sunday, would give Amgen three approved cancer treatments and several others in clinical trials.
The S&P 500 index was up three points, or 0.2 percent, to 1,666 after the first hour of trading. Health-care companies led six of the 10 industry sectors in the S&P 500 slightly higher.
The Dow Jones industrial average edged up 15 points, or 0.1 percent, to 15,024. The Nasdaq composite index rose nine points, or 0.3 percent, at 3,667.
In economic news, the government reported that orders for long-lasting U.S. factory goods plunged 7.3 percent last month, the steepest drop in nearly a year. Demand for commercial aircraft sank and businesses spent less on computers and electrical equipment.
News that members of the Pritzker family have agreed to buy TMS International sent the company's stock up 12 percent. The deal values the service provider to steel mills at roughly $1 billion. The Pritzker family, one of America's wealthiest, operates a global industrial conglomerate and founded the Hyatt hotel chain. TMS jumped $1.81 to $17.38.
With five trading days left in August, the major indexes are on track to end the month with slight losses. The Dow is down 3 percent for the month and the S&P 500 is down 1 percent.
In the market for U.S. government bonds, the yield on the 10-year note slipped to 2.79 percent from 2.82 percent late Friday. That followed an even sharper decline on Friday, when the declined seven basis points.
Crude oil slipped 2 cents to $106.38 a barrel and gold rose 40 cents to $1,396 an ounce.
