Gains in big technology companies led stocks broadly higher on Wall Street as traders welcomed some easing in long-term bond yields.
The S&P 500 index rose 0.7% Monday while the tech-heavy Nasdaq climbed 1.2%. Amazon, Apple, and Microsoft all made solid gains.
Kansas City Southern jumped 11.1% after a Canadian railroad announced it would buy the company for $25 billion. The yield on the 10-year Treasury note fell after trading as high as 1.74% last week. A steady rise in bond yields over the past month has been luring investors away from high-flying tech stocks.
