The S&P 500 and Dow Jones indexes edged lower on Thursday as a resurgence of COVID-19 cases globally sapped appetite for stocks, with data showing tepid U.S. home sales adding to the grim mood. American Airlines Group Inc and Southwest Airlines Co reported a smaller-than-expected quarterly loss, signaling a revival in travel demand. The performance of their shares was mixed though, with Southwest rising 0.5% and American Airlines falling 0.4%.
