A choppy day of trading on Wall Street ended with stocks closing higher Monday as investors brace for another big interest rate increase this week from the Federal Reserve.
The indexes swayed between modest gains and losses for much of the day before a burst of buying in the final hour of trading. The S&P 500 rose 0.7 percent, climbing back from a 0.9 percent slide. The Dow Jones Industrial Average rose 0.6 percent and the Nasdaq composite climbed 0.8 percent.
