US Tech Stocks Slide: Nvidia Loses Over $140B in Value

According to recent market reports, U.S. stocks saw sharp swings on Thursday as major tech names fell broadly. Early optimism around Nvidia's standout quarterly results was quickly overshadowed by renewed concerns about stretched valuations across the AI sector.

The tech-heavy Nasdaq Composite jumped more than 2% in early trading but reversed course to close down 2.2%, while the S&P 500 slipped 1.6%. Nvidia — widely viewed as a bellwether for the AI boom — initially surged over 5% after posting stronger-than-expected earnings late Wednesday, yet the stock ended the session down 3.15%, wiping out roughly USD 142.9 billion in market value.

Although Nvidia's robust results eased some near-term worries, investors remain cautious about whether competitors' valuations are sustainable and when the massive capital spending on AI infrastructure will translate into meaningful returns. Analysts note that sentiment has been fragile for weeks, and concerns continue to build despite strong earnings.

The pullback spread across the broader tech space. AMD tumbled 7.84%, Intel slipped 4.24%, Apple dipped 0.86%, Tesla fell 2.17%, Alphabet declined 1.15%, Meta edged down 0.2%, and Microsoft closed 1.6% lower.

This growing unease suggests that even strong performances from leading AI companies may no longer be enough to counterbalance the market's concerns about high valuations and heavy investment cycles.
