Tech rout weighs on U.S. stocks even after strong earnings from Palantir and Teradyne

U.S. equities closed lower as a tech-led selloff offset solid Q4 results from Palantir and Teradyne; the Nasdaq fell the most, while the S&P 500 and Dow also slipped. PayPal sank on weak guidance and a CEO change, and big-name techs like Nvidia, Microsoft, Amazon, and Apple ended lower. Gold and silver rebounded, lifting some risk assets as yields hovered around 4%, underscoring a volatile environment that traders were urged to navigate with an active, risk-aware approach.
