Nvidia is poised to announce fourth-quarter earnings, with analysts expecting adjusted earnings of 85 cents per share and net income of $19.58 billion. DeepSeek's assertions of resource-efficient AI model training have sparked worries, leading to a momentary $595 billion dip in Nvidia's market value. The company's stock holds significance in the U.S. market as the second-largest on Wall Street, impacting the S&P 500. CEO Jensen Huang is anticipated to offer reassurances on the company's standing and discuss competition from DeepSeek in the upcoming earnings call.
