AMD Shares Drop 8.75% as AI Chip Sector Faces Profit-Taking on Nov. 13

Advanced Micro Devices (AMD) shares fell 8.75% on November 13, 2026, closing at $534.06 as the stock market today experienced a notable rotation away from high-performing AI chip manufacturers. The decline marked a sharp reversal from early gains, as investors engaged in profit-taking across the semiconductor sector. Trading activity was intense, with 48.6 million shares changing hands, a volume approximately 98% higher than the three-month daily average of 24.6 million shares.

Market Trends and Sector Performance

The broader indices also faced downward pressure during the session. The S&P 500 concluded the day at 7,562, down 0.40%, while the Nasdaq Composite finished at 25,136, a decline of 0.91%. This movement reflected a wider trend affecting semiconductor rivals involved in CPUs, GPUs, and data-center accelerators. Intel shares dropped 2.52% to $59.66, and Nvidia shares fell 2.01% to $162.85, indicating that the sector-wide pressure was not isolated to a single company.

Despite the Friday decline, AMD had seen its stock price rise by as much as 30% earlier in the week, maintaining solid gains for the overall period. Market observers noted that the volatility was linked to ongoing uncertainty surrounding Nvidia’s outlook in the post-Jensen Huang era. AMD’s recent performance has been buoyed by strong financial reports; last week, the company announced third-quarter revenue of $13.4 billion, highlighting that data-center sales had nearly doubled compared to the previous year. This robust growth outlook for the data-center segment has been a primary driver for investor interest in the firm.

AMD shares retreated by 8.75% as a sector-wide sell-off reversed earlier gains in the AI chip market.

While some analysts suggest AMD could potentially benefit from shifts in the competitive landscape, the company’s long-term trajectory remains tied to the continued expansion of AI-related data center demand. Investors are currently looking ahead to Nvidia’s upcoming report to gauge the health of the broader AI chip market.

Why it matters

The recent pullback highlights the sensitivity of semiconductor stocks to sector-wide sentiment and rotation. For investors, the event underscores the importance of focusing on a company's underlying business strength, particularly in the data-center segment, rather than short-term market fluctuations.

This volatility reflects the current climate of uncertainty in the tech sector. As AI infrastructure continues to be a global priority, the performance of companies like AMD serves as a key indicator for the health of the broader technology market.
