The technology sector is experiencing a significant rally, primarily driven by blowout quarterly results and optimistic full-year guidance from AI-focused companies. Palantir Technologies surged after raising its revenue forecast, citing strong demand for its AI-powered software. Semiconductor companies are also seeing strong gains, with ON Semiconductor climbing on a better-than-expected forecast driven by demand for AI data center chips. This has bolstered investor sentiment across the AI space ahead of more tech earnings.
