AMD’s Chief Executive, Dr. Lisa Su, has sold a significant portion of her holdings in the semiconductor giant, a move disclosed in regulatory filings this week. The transaction, executed on December 11, 2025, involved shares worth approximately $27 million and coincides with a period of strategic refocusing and share price pressure for the company.
Analyzing the $26.9 Million Disposal
According to a Form 4 filing with the U.S. Securities and Exchange Commission (SEC), Dr. Su disposed of 125,000 shares at an average price of $215.14 per share. The total proceeds from the sale amounted to roughly $26.9 million.
This insider sale occurred as AMD’s stock faced headwinds, declining nearly 5% at the start of the week to trade around the $210 level. While such transactions are frequently pre-arranged under SEC Rule 10b5-1 trading plans, the timing has drawn market attention. It comes as AMD is realigning its strategy around its new “Helios” AI platform, an initiative critical to its competitive stance against rivals like Nvidia.
Analyst Maintains Bullish Stance Despite Volatility
In contrast to the recent share price weakness, investment firm Piper Sandler has reiterated its confident outlook on AMD. The firm’s analyst, Harsh Kumar, confirmed an “Overweight” rating for the equity, accompanied by a price target of $280. This projection implies a potential upside of about 33% from current trading levels.
Should investors sell immediately? Or is it worth buying AMD?
Kumar’s optimism stems from a recent discussion with AMD’s leadership team, which centered on the development of the Helios AI platform scheduled for mid-2026. Piper Sandler views this system as a fundamental component for AMD to capture meaningful market share within the rapidly expanding AI infrastructure sector, particularly in data centers. Other valuation models also suggest the stock may be undervalued; as of mid-November 2025, the estimated fair value stood near $244.
Technical Picture Tests Key Support Level
From a chart analysis perspective, AMD shares are navigating a tense technical environment. The stock is currently testing a crucial support band between $200 and $210. A sustained break below the psychologically significant $200 threshold could trigger further selling pressure.
Conversely, the combination of supportive analyst commentary and the long-term potential of the Helios project may provide a foundation for stabilization. The coming trading sessions will be pivotal in determining whether bullish investors can successfully defend this support zone.
