In Advanced Micro Devices Inc's own words

“We delivered an excellent quarter, with record revenue and profitability as Data Center revenue more than doubled year-over-year”

— Dr. Lisa Su, AMD chair and CEO · SEC filing

From the company's earnings release filed with the SEC on 2026-08-04 (Form 8-K).

What would change the picture for AMD

These are the specific events and levels to watch. None of them is a prediction.

• The Nov. 3, 2026 earnings report is 15 days away. Advanced Micro Devices Inc beat estimates in all 4 of the last 4 quarters, with an average surprise of +5.9%. A miss would break that pattern.
• Insider buying: none on the open market in 90 days. A purchase by an executive or director would be the first in at least three months. It would show up on SEC Form 4 within two business days.
• Analyst ratings: the average score moved from 4.05 to 4.12 over three months. The scale runs from 1 for strong sell to 5 for strong buy. A run of downgrades after earnings usually shows up here first.
• Price levels: a close above $649.42 would be a new 52-week high. That is 22.8% above the latest close of $528.75. A close below $190.95 would be a new 52-week low, 63.9% below it.
• Growth: revenue rose 39.5% year over year in the quarter ending Jun 2026. The trend is accelerating. At a P/E of 135.9, a slowdown would matter more than at a lower multiple.
• New shares: dilution risk is moderate now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.

How AMD compares with its peers

Over the past month, AMD ranks 2 of 6 in this group at -3.0%. NVDA was best at -2.4%, and INTC was weakest at -17.4%.

AMD's P/E of 135.9 is above the peers' median of 23.4. Investors pay more for each dollar of its profit, usually for faster expected growth.

A dash in the P/E column means the company lost money over the last 12 months. It has no P/E.
