Advanced Micro Devices (NASDAQ: AMD stock) slipped nearly 3% on Thursday as investors looked past an important overseas trip by Chief Executive Lisa Su and focused instead on a more immediate problem.
The plunge on Thursday came amid broader market weakness as the oil prices continue to rise and the Iran-US conflict is escalating with strikes on cargo ships in the Persian Gulf.
AMD stock remained in focus as Lisa Su is heading into a high-profile visit to South Korea next week, where she is expected to hold strategic talks with Samsung Electronics and Naver.
AMD stock: Market pressure overshadowed the trip
The clearest explanation for AMD’s softer share performance is the broader market backdrop.
The analysts pointed out that Thursday’s pullback should not be seen as a verdict of Lisa Su’s South Korea visit, which is important from supply-chain perspectives.
When investors turn to risk-off mode, the chip stocks, especially companies tied to artificial intelligence spending, tend to be hit quickly.
Even when the long-term story remains intact, traders often reduce exposure to higher-growth technology names first when macro tensions intensify and market volatility rises.
Moreover, the AMD stock has earned some caution after its February earnings report.
AMD beat Wall Street estimates, but the shares still fell sharply after guidance was seen by some analysts as underwhelming relative to the market’s lofty AI expectations.
In early February, Su tried to reassure investors by saying demand for AMD’s products was “on fire” and calling 2026 an “inflection year” for the company, but that did not stop the stock from selling off.
Why the South Korea visit still matters
Lisa Su is expected to visit South Korea on March 18 for meetings with Samsung chairman Jay Y. Lee and Naver chief executive Choi Soo-yeon.
A central issue in the Samsung talks will be securing supplies of high-bandwidth memory, or HBM, a crucial component used in AI chips.
The visit is crucial for AMD as demand for AI accelerators rises; memory supply has become one of the most important bottlenecks in the industry.
AMD is looking to lock in reliable HBM access to improve its ability to compete in the next phase of the data-center buildout.
Su’s meeting with Naver is also expected to cover broader cooperation around data-center chip supply, sovereign AI infrastructure, and next-generation computing.
In simple words, a South Korea trip is a medium-term catalyst rather than an instant stock mover.
Thursday’s sell-off came amid broader market weakness, and it doesn’t seem like the company is facing any specific operational setback.
If Su can return from South Korea with stronger partnerships around memory and AI infrastructure, the trip may end up being remembered as strategically important even if Wall Street did not reward the stock in advance.
