Jim Cramer: This partnership could be a 'seismic shift' in AI and 2 of our stocks

Every weekday, the CNBC Investing Club with Jim Cramer holds a "Morning Meeting" livestream at 10:20 a.m. ET. Here's a recap of Thursday's key moments. 1. Stocks were mixed Thursday as investors tried to handicap whether the U.S. and Iran were moving closer to an agreement to end the war , alongside a sharp rotation underneath the surface "It's been hardware, hardware, hardware," Jim Cramer said. "Suddenly today, it's reversing." Software stocks gained following a strong batch of earnings. Red-hot chip designer Arm Holdings was part of the hardware contingent under pressure. The Club stock saw a post-earnings drop of more than 8% as investors focused on the company's challenges to secure enough supply for its new in-house CPUs to raise its official revenue forecast. 2. Software stocks popped , with cybersecurity names among the biggest winners. Strong results from firewall powerhouse Fortinet lifted the broader group, including Club names CrowdStrike and Palo Alto Networks . Jim acknowledged lingering concerns that AI could eventually disrupt cyber vendors, but said the rebound shows investors are regaining confidence. We have favored CrowdStrike over Palo Alto, though we own both. Jim and Jeff Marks, director of portfolio analysis for the Club, admitted it's "tempting" to take profits in Palo Alto after the stock went back into the green for the year. Still, the pair noted that improving cybersecurity sentiment and Palo Alto's upcoming earnings could create room for further upside. 3. Jim also highlighted the partnership between Club stocks Nvidia and Corning as a potentially "seismic shift" for AI infrastructure. Corning on Wednesday announced plans to increase optical fiber connectivity manufacturing capacity tenfold. Corning shares were modestly lower Thursday, one day after jumping 12% on that Nvidia deal and positive Investor Day comments. Jim said the industry is increasingly moving away from copper and toward fiber inside data centers. "The copper linking is going to be pulled out. It's going to be fiber. Fiber is better," Jim said. He added that replacing copper inside Nvidia's next-generation Vera Rubin systems with fiber — which has not happened yet — could dramatically reduce heat constraints. Both Nvidia CEO Jensen Huang and Corning CEO Wendell Weeks will appear on " Mad Money " Thursday night. 4. Stocks covered in Thursday's rapid fire at the end of the video were: McDonald's , Shake Shack , DoorDash , Fortinet , and Datadog .
