Why Nvidia Stock Plummeted This Week

Nvidia (NASDAQ: NVDA) stock saw a big valuation pullback in this week's trading. The graphics processing unit (GPU) leader's share price fell 15.8% from its level at the previous week's market close, according to data from S&P Global Market Intelligence. Nvidia was hit with sell-offs this week as information surrounding the new R1 artificial intelligence (AI) model from DeepSeek signaled a potential paradigm shift in AI training and inference.
