AMD’s Chief Technology Officer and EVP, Mark D. Papermaster, sold 6,181 shares on 2026-08-20 at $466.60 per share, a transaction worth about $2.88 million. Because Papermaster is a top executive overseeing AMD’s technology direction and product roadmap, his trades tend to draw attention from investors looking for signals from leadership. This sale was reported as being made under a pre-scheduled Rule 10b5-1 trading plan, which is a written program that sets up trades in advance and is commonly used to avoid the appearance of trading on nonpublic information. Trades executed under these plans are often viewed as more routine than discretionary, one-off sales, though investors still watch for changes in size or frequency over time. The transaction also fits into a broader cluster of insider selling over the past month at AMD. In addition to Papermaster’s sale, CEO Lisa Su sold about $333,000 on 2026-08-18, Ava Hahn sold about $1.46 million the same day, Paul Darren Grasby sold about $7.72 million on 2026-08-17, and Papermaster sold another roughly $3.59 million on 2026-08-14. A series of sales can reflect planned diversification or tax-related selling, and the presence of 10b5-1 plans is an important detail when assessing how much weight to place on the activity.
