By Joe Wallace Stocks climbed in early trading Monday as investors awaited a slate of Federal Reserve speakers and data on the manufacturing sector. The S&P 500 rose about 1.3% and the Nasdaq Composite Index advanced 1.6% after a bruising week for technology stocks. The Dow Jones Industrial Average added 397 points, or 1.3%. The broad advance came as the yield on 10-year Treasury notes, the benchmark borrowing cost in global debt markets, slipped to 1.43% from 1.459% Friday. Yields fall when bond prices rise. Stocks, and particularly shares of tech companies, have been buffeted by volatile moves in government-bond markets in recent trading sessions. A lurch higher in yields last week called into question the prospect of a long period of low interest rates, which had underpinned the past year's booming rally in stocks.
