Shares of Advanced Micro Devices, Inc. (NASDAQ:AMD) are trading lower by 4.8% due to possible sympathy with Texas Instruments Inc, which reported worse-than-expected Q3 sales results and issued Q4 revenue guidance below estimates. This could indicate potential issues in the broader supply chain, leading to concerns about semiconductor shortages and disruptions, which might negatively impact AMD. Lower sales and weaker revenue guidance from Texas Instruments could also be seen as a sign of broader economic challenges or slowdowns.
