AMD Advanced Micro Devices

$534.06-$51.24 (-8.75%)

NASDAQ · As of 4:00 PM ET 11/13/26

Advanced Micro Devices (AMD -8.75%), a supplier of AI and general-purpose chips for PCs, servers, and embedded systems, closed at $534.06, down 8.75%. Friday’s drop followed a sharp reversal from early AI-chip name buying into a sector sell-off. Investors are watching Nvidia‘s report next week and AI chip demand.

Trading volume reached 48.6 million shares, coming in about 98% above its three-month average of 24.6 million shares.

How the markets moved today

The S&P 500 (^GSPC -0.40%) closed at 7,562, down 0.40%, while the Nasdaq Composite (^IXIC -0.91%) finished at 25,136, down 0.91%. Among semiconductor rivals in CPUs, GPUs, and data-center accelerators, Nvidia closed at $162.85, down 2.01%, and Intel closed at $59.66, down 2.52%, reflecting the same AI-chip rotation pressure.

What this means for investors

AMD stock was up as much as 30% this week, and still ended the week with solid gains, despite today’s decline. AMD investors shouldn’t be overly concerned with how the stock performed Friday. It was caught in the downdraft stemming from uncertainty surrounding Nvidia in its post-Jensen Huang era.

Last week, AMD reported third-quarter revenue of $13.4 billion and said data-center sales nearly doubled year over year. The strong outlook for its data center segment, along with similar comments from other AI-related names this week, helped the stock before today’s pullback.

AMD could benefit from Nvidia’s internal struggles, but investors should continue to focus on AMD’s underlying business strength. As long as the AI-related data center growth continues, the company looks to have a long growth runway.
