Advanced Micro Devices (AMD) stock dropped $28.22, or 4.66%, to $577.31 as the 10-year Treasury yield climbed to 5.278% after the Consumer Price Index (CPI) release. This decline interrupts a historic run, with AMD shares surging 182.8% year to date, outperforming the computer and technology sector’s 22.7% gain.
The stock’s beta of 2.45 explains the gap in its decline compared to other semiconductor stocks, which fell less sharply. By late morning, AMD’s decline had widened, while Nvidia held near its early loss of 2.33%. AMD’s valuation, at 148 times trailing earnings and roughly 50 times forward earnings, has no cushion when the 10-year Treasury jumps and the semiconductor index slides.
AMD’s second-quarter results showed revenue of $11.5 billion, up 50% year over year and 13% sequentially, a company record. Data Center revenue jumped 107% to $6.7 billion, driven by strong demand for EPYC server processors and Instinct GPUs. The company has guided to a 2027 doubling of Data Center revenue, which would push the segment above $50 billion.
Management’s tone was confident, with CEO Lisa Su saying EPYC demand is accelerating and Helios is beginning to ramp. The Helios rack-scale system, launched in July, connects 72 Instinct MI455X GPUs into a single scale-up domain with 31 terabytes of unified HBM4 memory. The system is priced between $5 million and $5.5 million per cabinet, with shipments starting in the third quarter.
AMD’s Data Center Growth
This scale separates AMD from previous attempts to challenge Nvidia and provides visibility into revenue. However, it also concentrates risk, as a handful of AI developers account for most of AMD’s forward AI revenue.

AMD’s server CPU business, led by EPYC processors, holds 46% of the revenue share in the server CPU market, with growth expected to exceed 80% year over year in the second half of 2026. The CPU business provides a cushion against GPU volatility and supports overall profitability during the GPU ramp. With a valuation that reflects its 2027 story, AMD’s stock is pricing in growth well beyond current forecasts.
AMD’s forward guidance is aggressive, with revenue expected to reach $13.0 billion in the third quarter, implying 41% year-over-year growth at the midpoint. The company expects Data Center revenue to grow strong double digits sequentially in the third quarter, with further acceleration in the fourth quarter as Helios shipments ramp.
The 2027 outlook is a key factor in AMD’s valuation, with the company expecting Data Center segment revenue to more than double year over year. This growth is expected to be driven by strong demand for EPYC server processors and Instinct GPUs, as well as the ramp of Helios shipments. AMD’s valuation reflects this growth story, but it also poses a risk if the company fails to meet its guidance.
As of Wednesday, AMD’s stock had lost 8.42% over the past week, and it sits 12.3% below its 52-week high of $658.52. The stock’s valuation, combined with its historic run, makes it vulnerable to declines if the company’s growth slows or if the market becomes less optimistic about its prospects.
AMD’s beta of 2.45 means that its stock price is likely to be more volatile than the overall market, which could lead to larger declines if the market experiences a downturn. However, the company’s strong financials and guidance suggest that it is well-positioned for long-term growth, despite the near-term risks.
Helios Drives AI Revenue
AMD’s Data Center business is a key driver of its growth, with revenue jumping 107% to $6.7 billion in the second quarter. The system’s pricing, between $5 million and $5.5 million per cabinet, reflects its high-performance capabilities and the demand for AI acceleration.

At $577.31, AMD is valued at $943.62 billion, below the $1 trillion mark it crossed earlier this month. Reclaiming that milestone requires a share price above $613.50, 6.3% above the current level. The stock’s 52-week range now spans $188.22 to $658.52, and its decline on Wednesday was the largest among its peers, including Nvidia, Broadcom, and Intel.
AMD’s server CPU business is the quieter half of its Data Center story, and it may be the more durable one. AMD now holds 46% of revenue share in the server CPU market, a stunning reversal from a decade ago, when Intel controlled nearly the entire market. EPYC processors have taken share every year since their 2017 launch, and AI is accelerating that shift.
Server CPU Business Surges
The growth rates are exceptional for a mature product category. AMD expects server CPU revenue to grow more than 80% year over year in the second half of 2026 and more than 70% in 2027. These numbers come off a large base, which makes them more impressive than the AI GPU growth rates. The connection between AMD’s server CPU growth and broader growth in agentic AI infrastructure is evident, with Akamai’s distributed cloud running heavily on AMD EPYC processors.
The CPU business also provides a cushion against GPU volatility. If MI450 shipments slip or AI customers pause orders, EPYC demand from traditional cloud and enterprise workloads keeps revenue growing. Management noted that strong server CPU growth provides an offset to quarter-to-quarter mix shifts in the GPU business. Margins favor CPUs, with server processors typically carrying higher gross margins than the MI450.
The level of $560 marks a 15% correction from the $658.52 high and the first zone where buyers have historically stepped into momentum leaders.
