Market movers
Nvidia (NVDA 1.53%) extended its post-earnings slide and turned negative for 2026, amplifying the AI-linked sell-off. However, Dell (DELL +1.69%) soared 21.93% to close at $148.08 as investors responded positively to its growth forecast.
Ambarella (AMBA 2.89%) plunged more than 18% in intraday trading despite positive earnings. Zscaler (ZS 1.40%) erased yesterday’s gains. The firm beat analyst expectations, but sank on billings concerns.
The bidding war for Warner Bros. Discovery (WBD 1.33%) seems to have reached a conclusion, depending on regulatory approval.

What this means for investors
Today’s Producer Price Index (PPI) data shook markets. Wholesale prices increased by 0.8% in January, much more than economists had predicted. Higher inflation could delay Fed rate cuts. The inflation data came on top of jitters over private credit, ongoing AI bubble nerves, and geopolitical tensions.
Financial stocks came under particular strain this week. The collapse of Market Financial Solutions, a U.K. mortgage lender, sparked contagion fears. Plus, Block (XYZ 7.42%) announced it would lay off around 40% of its staff, adding to sector-wide AI disruption worries.
