Wall Street kicked off the week with a broad rally Monday, clawing back much of the stock market’s losses from last week.
The S&P 500 rose 1.3 percent, led by gains in technology, health care and financial stocks. Small-company stocks were among the biggest gainers. The rally reversed a big slice of the index’s 2.5 percent slide last week, when the S&P 500 posted its biggest weekly decline since June. Treasury yields were mostly higher.
