(Reuters) - Wall Street ended lower after a choppy session on Monday, with declines in Exxon Mobil (NYSE:XOM) and other energy companies weighing against gains in Boeing (NYSE:BA) as investors digested the U.S. stock market's biggest monthly gains in two years.
Stocks gave up some of a strong rally from last week that was driven by bets the Federal Reserve may not need to be as aggressive with interest rate hikes as some had feared.
Also helped by stronger-than-expected second-quarter results, the S&P 500 and the Nasdaq in July posted their biggest monthly percentage gains since 2020.
The S&P 500 bounced between gains and declines on Monday as some investors became more cautious in the wake of that recent rally.
The Federal Reserve says it aims to tame inflation and cool down demand with the interest rate hikes, but some investors and analysts worry that its aggressive moves could drive up unemployment and cripple the economy.
