NEW YORK: Stocks fell in Monday trading, with the Standard & Poor’s 500 Index’s halting two days of gains.
Tyson Foods Inc., the largest U.S. meat processor, slid 7.3 percent after Bank of America Corp. analysts cut their rating on the stock.
Archer-Daniels-Midland Co., the largest corn processor, dropped 4.9 percent as hot, dry weather in the Midwest threatened to reduce crop harvests.
Amgen Inc. jumped 7.7 percent after agreeing to buy cancer-treatment developer Onyx Pharmaceuticals Inc. in a $10.4 billion transaction.
The S&P 500 declined 0.4 percent to 1,656.78.
The Dow Jones industrial average lost 64.05 points, or 0.4 percent, to 15,946.46.
The S&P 500 spiked lower after earlier extending its first weekly gain since Aug. 2, as investors speculated whether a report showing durable-goods orders fell in July would delay stimulus cuts.
