Nvidia, the dominant maker of artificial intelligence chips, suffered its worst stock decline in 10 months after the company's latest forecast failed to dispel fears of an AI bubble. The shares fell 5.5% to $184.89 in New York, marking the biggest one-day drop since April 16. The decline followed a first-quarter sales outlook that on its face looked impressive. Nvidia easily beat the average analyst estimate and delivered a 73% surge in fourth-quarter revenue. The reaction was a stark reminder of the skepticism now surrounding Nvidia. After explosive sales growth turned the chipmaker into the world's most valuable company, investors are seeking stronger assurances that booming AI spending can be maintained. Bloomberg Intelligence Senior Semiconductor Analyst Kunjan Sobhani, and Senior Technology Credit Analyst Robert Schiffman both join Bloomberg Businessweek Daily to discuss. They speak with Carol Massar and Tim Stenovec.
