The direction of the AI trade is shifting.
In the past, chip stocks could command generous valuations from the market simply by having exposure to AI. But as massive capital spending by tech giants raises concerns about cash flow, and as Intel's disappointing guidance triggered a brutal selloff, investors have begun to re-examine the growth logic of the AI supply chain.
For Advanced Micro Devices (AMD), which is set to report earnings after the bell on Tuesday, the market is no longer asking for just a solid result. It must deliver sufficiently strong performance and even more aggressive forward guidance to prove it still deserves its high valuation.
So far this year, AMD shares have risen about 118%, far outpacing the 46% gain in the Philadelphia Semiconductor Index. But as sentiment around the AI trade suddenly cools, that rally has put AMD in a delicate position: the higher the growth expectations, the smaller the margin for error on earnings.
Neville Javeri, a portfolio manager at Allspring Global Investments, said bluntly that for AMD to sustain its current momentum, it needs "not just a beat, but a significant beat, accompanied by quite strong guidance. A moderate performance is no longer enough."
Intel's plunge puts AMD under the same scrutiny
Intel's experience has already sounded an alarm for AMD.
Before reporting earnings, Intel had been one of the best-performing chip stocks in the U.S. market this year. AI infrastructure buildout drove demand for CPUs, and the company's share price rose as much as 150% in 2026.
However, weak guidance completely changed market sentiment.
Last Friday, Intel shares suffered their worst single-day decline since 1982. By Monday's close, its year-to-date gain had narrowed sharply from 150% to 63%.
AMD was not spared from the selloff either.
On Friday, AMD shares fell 10% in a single day, bringing their October decline to more than 17%. Even so, the stock is still up 118% year to date, significantly outperforming the semiconductor sector.
The market logic facing both companies is quite similar: AI demand once drove sharp share price gains, and when investors begin to question whether that growth can continue, valuations built on optimistic expectations can quickly come under pressure.
The bigger issue is that the market's attitude toward AI spending is also changing.
Over the past two weeks, massive capital expenditure plans from AI giants such as Alphabet, Meta and Amazon have sparked market concerns. Investors are starting to focus on whether these investments are eroding cash flow and whether AI infrastructure buildout can continue to expand at its current pace.
For chip companies that depend on sustained AI investment for growth, this shift in sentiment undoubtedly creates pressure.
With the stock up 118%, AMD's earnings bar has been raised
From a fundamental perspective, AMD is not lacking in growth support.
Wall Street expects AMD's third-quarter profit to rise 92% year over year, with revenue up 41%. Analysts also expect both metrics to grow further in 2027.
CEO Lisa Su also said last month that chip demand over the next few years will be "very high" and exceed supply capacity.
But the problem is that the share price has already priced in quite optimistic expectations.
As of now, AMD trades at about 32 times forward earnings for the next 12 months, ranking fourth among Philadelphia Semiconductor Index constituents. Although that valuation is below the 56 times high reached on June 30 this year, it remains relatively expensive.
Historically, AMD's average forward price-to-earnings ratio since 2017 has been about 34 times.
This means that even if AMD's results meet or slightly exceed market expectations, that may not be enough to push the stock higher.
What the market really wants to see is further acceleration in growth.
Over the past three months, Wall Street's expectations for AMD's 2027 net profit have been revised up 23%, revenue forecasts have been raised 14%, and 2028 projections have seen even larger increases. The average analyst price target compiled by Bloomberg suggests AMD still has about 40% upside over the next 12 months.
But continuously rising expectations also mean that the market consensus before earnings has become more aggressive.
Once results or guidance fail to meet that bar, the stock could face a dual adjustment in both valuation and expectations.
Can Muse become AMD's "beat-and-raise engine"?
AMD still has one important growth catalyst: AI agents.
With the rapid development of AI agents, the role of CPUs in AI infrastructure is drawing renewed attention. Unlike GPUs, which mainly handle AI model training and inference, CPUs play a key coordination and control role in running agents.
The success of Meta's Muse has further reinforced market attention on this trend.
According to data compiled by Bloomberg, CPUs contributed nearly a quarter of AMD's revenue in 2025. Meta is AMD's second-largest customer, accounting for 5.5% of its revenue.
Muse's popularity has also prompted some analysts to raise their price targets for AMD. Rosenblatt Securities analyst Kevin Cassidy even named AMD his top pick ahead of earnings.
Allspring's Javeri believes investors need to see evidence of accelerating growth, and Muse is undoubtedly a credible catalyst.
If AI agents drive further growth in CPU demand, AMD does have an opportunity to move from good growth to hypergrowth.
But that is still an expectation that needs to be validated by results.
Whether the rise of AI agents can continue to translate into actual orders, revenue and profit growth for AMD remains a question the market needs to observe. At the same time, whether AI infrastructure spending slows will also directly affect the sustainability of chip demand.
Wall Street is no longer willing to pay for a "growth story"
The shift in market sentiment has already begun to affect how investors act.
Jim Worden, chief investment officer at Wealth Consulting Group, said that due to an uncertain macroeconomic backdrop and AMD's elevated valuation, he has exited his position in AMD, though he continues to hold other chip stocks such as Nvidia, Broadcom and TSMC.
He noted that AMD does have the potential to move from good growth to hypergrowth, and factors such as Muse could serve as accelerators, but he is not comfortable with the current valuation. "There are just too many questions," he said.
Those remarks reveal the core contradiction AMD currently faces.
On one hand, AI agents, growing CPU demand and expectations of supply shortages in the coming years provide fundamental support for continued growth. On the other hand, the sustainability of AI capital spending, market valuation and investors' sensitivity to earnings disappointment are creating growing pressure.
AMD's earnings report is no longer just a test of revenue and profit, but a test of the entire AI trade logic.
If the company can deliver a significant earnings beat and sufficiently strong forward guidance, the market may still embrace its growth story again.
But if it merely delivers an in-line scorecard, then against the backdrop of Intel's plunge and intensifying concerns about AI spending, an ordinary performance will likely struggle to preserve market confidence.
As investors begin to demand that AI companies prove their spending can translate into returns, the question AMD needs to answer is no longer just "how fast is growth," but "how much faster can growth still become."
