Chip retreat caps mixed session as TSMC earnings weigh on futures

US stock futures are mixed: Dow futures edge higher while S&P 500 and Nasdaq-100 futures slip as chip names come under pressure after Taiwan Semiconductor Manufacturing Co.’s earnings.

Meanwhile, UnitedHealth Group and GE Aerospace beat estimates, Netflix is set to report later, and traders await retail sales and jobless claims data, all amid ongoing geopolitical tensions and oil-market volatility.
