Advanced Micro Devices Stock Continues Rally After OpenAI Deal, Now up 31% This Week so Far

AMD stock climbed 11% on Wednesday, continuing a massive run since OpenAI announced plans to buy billions of dollars of AI equipment from the chipmaker earlier this week.

On Monday, the ChatGPT maker entered into an agreement to potentially own 10% of AMD, based on its stock price and partnership milestones.

AMD now has a market cap of $380 billion after climbing 4% on Tuesday and 24% on Monday. Shares are up 31% so far this week.

Dell Technologies Inc. Stock Pops as Company Ups Long-Term Revenue Growth Expectations

Shares of Dell Technologies rose 3.5% Tuesday after the company increased its long-term revenue and profit growth expectations in a meeting with analysts.

The computer maker said it now expects annual revenue to expand between 7% and 9%, an increase from its prior forecast of 3% to 4%.

For the full year, it now expects diluted earnings per share to grow at least 15%, compared with its previous expectations for growth of 8% or higher.

Netflix Stock: Up as Streamer Rolls Out ‘Clue’-Inspired Reality Series

Netflix closed trading on October 7 at $1,191.06, marking a 2.39% gain for the day.

The rise in stock followed the streamer’s announcement of an unscripted competition series featuring “Clue’s” iconic characters and murder-mystery theme. Contestants will engage in physical and mental challenges while solving classic whodunit scenarios. With no confirmed premiere date, the project still generated strong buzz and social media traction.

Netflix continues expanding its non-scripted slate, and this latest move signals confidence in adapting nostalgic IPs. Earlier this year, it secured a similar deal for a “Monopoly” series. Analysts credit this strategy for reinforcing Netflix’s original content appeal, helping it maintain momentum in a crowded streaming market.

Pepsi's Earnings Top Projections; Walmart's Schmitt to Take Over as CFO

PepsiCo posted quarterly earnings slightly ahead of analysts' expectations and announced a new chief financial officer on Thursday.

The maker of Pepsi soda and Doritos chips posted adjusted earnings per share of $2.29 on revenue that rose 2.7% year-over-year to $23.94 billion for the third quarter. Both figures topped analysts' projections compiled by Visible Alpha, thanks in part to strength in the snack giant's international business and improvements in its North American beverage operations.

PepsiCo also said that Steve Schmitt, chief financial officer for Walmart's U.S. unit, will take over as chief financial officer from Jamie Caulfield effective Nov. 10. Caulfield decided to retire next year after more than 30 years with the company, PepsiCo said. He became CFO in December 2023.
