Nvidia's stock fell more than 6% in a sharp one-day selloff that wiped out about $320 billion in market value and pushed the company below a $5 trillion market capitalization. The move highlights how quickly sentiment can shift around AI-linked investments and the broader semiconductor sector, while reinforcing the sensitivity of high-growth technology names to macroeconomic signals, regulatory pressure and wider risk appetite. The development also serves as a reminder that swings in major tech stocks can influence sentiment across adjacent markets, including crypto.
