Advanced Micro Devices Probes Local Dynamic Floors Following Sharp Pullback

Advanced Micro Devices (NASDAQ:AMD) closed Friday, October 23, at $516.79, up 1.74% on the day, after a pullback that took the stock 20.42% below its $649.42 record close of October 6. The decline reached its low point on Thursday, October 22, when AMD fell 8.10% to $507.93 and touched $502.60 intraday during a steep one-day drop for semiconductor shares. That low landed within about 1% of the $497.51 September low and near a set of September closes between $503.60 and $516.13. Friday's rebound closed within 66 cents of the September 11 close. With third-quarter results due on Tuesday, November 3, after the close, this article walks through the pullback, the floors the stock is probing, what AMD has announced and how bulls and bears are reading the setup.

 

AMD's most important announcement this year was its second-quarter report on August 4. Revenue rose 50% year over year to a record $11.5 billion, gross margin was 54%, operating income was $2.0 billion, and diluted earnings per share were $1.38, or $1.66 on a non-GAAP basis. Data Center revenue more than doubled, rising 107% to $6.7 billion and representing 58% of company revenue, while Gaming revenue fell 31% to $779 million on lower semi-custom sales.

Management guided third-quarter revenue to approximately $13 billion, plus or minus $300 million, with non-GAAP gross margin of about 56%. CFO Jean Hu said AMD expects Data Center sales to accelerate in the second half of 2026, and CEO Lisa Su said EPYC demand is accelerating, Instinct deployments are scaling and the Helios rack-scale platform is beginning to ramp. Management also said it expects Data Center revenue to more than double in 2027. AMD announced on October 6 that it will report third-quarter results on Tuesday, November 3, after the market close.

Analysts have kept moving targets higher into the report. On October 21, Susquehanna raised its AMD target to $620 from $550. The week also brought a collaboration expansion with Vultr for new AI infrastructure in India.

 

The pullback began from a very strong September. After closing at $493.41 on September 14, AMD gained 31.6% over the next 16 sessions to its $649.42 record close on October 6, including a 9.95% jump on September 21 on about 44.5 million shares, the heaviest volume of the 50-session window.

The decline then came in stages. AMD fell 0.55% on October 7, 3.90% on October 8, 2.03% on October 9 and 2.28% on October 12, then bounced 1.90% on October 13 to $605.53. It fell 5.73% on October 14 to $570.82 and 1.50% on October 15 to $562.23. On October 15 it traded in a range of about 6.9% of the close, the widest of the window, and on October 16 it fell 5.95% to $528.75 as the Nasdaq Composite lost 2.1%.

Thursday, October 22, was the low point. The Nasdaq Composite fell 2.60% to 26,008.86, its steepest one-day drop since June, and the S&P 500 lost 1.21%. The Philadelphia Semiconductor Index fell 6.72% to its lowest level since July 29, with all 30 members lower. Lam Research fell 11.76% after warning that supply-chain constraints would delay shipments, AMD lost 8.10%, Intel lost 8.04%, Marvell lost 8.70% and Micron lost 6.26%. Market coverage tied the selloff to renewed worries about financing the AI buildout after heavy spending disclosures at Meta and comments from Nvidia CEO Jensen Huang about the working capital of smaller AI cloud providers. About 27.5 million AMD shares traded.

Friday's session brought a partial recovery. AMD opened at $510.21, traded between $508.36 and $523.92 and closed at $516.79, with the Philadelphia Semiconductor Index up about 0.6%. For the week, the stock lost 2.26%, compared with a 0.7% decline for the Nasdaq Composite.

 

The chart story is a floor built in September. AMD closed at $505.74 on September 8, $503.60 on September 10, $516.13 on September 11, $493.41 on September 14, $504.20 on September 15 and $512.50 on September 16. Session lows in the area were $502.81 on September 10, $480.33 on September 14 and $497.51 on September 15. Thursday's $502.60 low landed 1.02% above the September 15 low and within 21 cents of the September 10 low, and Friday's $516.79 close finished within 66 cents of the September 11 close.

 

 

The distance from the record is large. Friday's close is 20.42% below the record close and 21.52% below the intraday record, and the October 22 low of $502.60 was 23.68% below the $658.52 high. Peak to trough on a closing basis, the stock fell 21.79%, from $649.42 to $507.93.

Moving averages show the short-term picture. Calculated from daily closes, the 20-day simple moving average sits near $587.22 and the 50-day near $542.28, which places Friday's close about 12.0% below the shorter average and about 4.7% below the longer one.

Volatility has been high throughout. Seventeen of the last 49 daily closes moved 3% or more in either direction, and six moved 5% or more. The 52-week range runs from $188.22 to $658.52, and the stock remains about 141% above its 2025 close of $214.16.

 

The floor hold reading. Bulls point out that Thursday's low landed in an area the stock has already visited, within about 1% of the September 15 low and within 21 cents of the September 10 low, and that the stock rebounded on Friday while peers rebounded too. Micron gained 2.46% and Intel gained 1.72%. Fundamentally, AMD's second-quarter revenue rose 50%, Data Center sales more than doubled and management guided third-quarter revenue to about $13 billion. The stock is still up about 141% for 2026, and Susquehanna raised its target to $620 days before the selloff.

The deeper reset reading. Bears note that the stock closed 12.0% below its 20-day average and 4.7% below its 50-day average, that it fell 20.42% in 13 sessions and that the weakness is tied to a sector-wide reassessment of AI spending rather than an AMD-specific event. Under this view, the September band is simply the next place the market tests.

Both camps are looking at the same chart. The disagreement is whether the September floor holds as a base or acts as a waypoint, and the November 3 report is the next dated test.

 

Traders watching AMD should separate three kinds of risk. The first is event risk. AMD reports after the close on Tuesday, November 3, and a stock that fell 8.10% in a single session this week and 5.95% a week earlier can gap meaningfully in either direction on a print.

The second is sector risk. AMD fell with Intel, Micron, Marvell and Lam Research on Thursday, and Alphabet, Microsoft and Amazon all report next week with capital spending forecasts under scrutiny. The Federal Reserve also meets on October 27 and 28, and oil prices topped $100 a barrel on Friday.

The third is level risk. The September floor is visible on any chart, so reactions near it can be sharp in either direction. Context matters too. Even after the pullback, the stock is up about 141% for the year and about 175% above its 52-week low. This article is informational and is not financial advice.

 

AMD has pulled back 20.42% from its record close and is now probing a floor that formed in early and mid September, with Thursday's $502.60 low landing within about 1% of the September 15 low and Friday's close nearly matching the September 11 close. The fundamentals going into the report are strong, with revenue up 50%, Data Center sales up 107% and third-quarter guidance of about $13 billion. The November 3 report is the next dated test. Do you think the September floor holds through earnings, or does the 20-day average near $587 stay out of reach for now?
