US stock futures were flat on Thursday following another turbulent session on Wall Street, as investors weighed upbeat bank earnings, persistent US-China trade frictions, and the ongoing government shutdown. On Wednesday, the S&P 500 and Nasdaq Composite advanced 0.4% and 0.66%, respectively, while the Dow slipped 0.04%. The S&P 500 swung between gains of 1.2% and losses of 0.48% during the session. Strong quarterly results from Morgan Stanley and Bank of America highlighted robust dealmaking activity, while solid earnings from ASML underscored steady AI-related demand. Meanwhile, markets remained cautious amid renewed trade sparring between Washington and Beijing and as the shutdown extended into its third week. Investors now look ahead to more corporate results, with Salesforce, United Airlines, and J.B. Hunt Transport Services seeing sharp moves in after-hours trading.
