Super Micro Computer Inc shares fell 4.71% to $34.10 on Thursday as an export-control case involving company-linked individuals continues to weigh on investor sentiment.
A broader decline in technology and AI-related stocks added to the pressure. The Nasdaq dropped 1.17%, while the S&P 500 shed 0.26%, with the technology sector leading the downside at a 2.1% loss.
Contractor pleads guilty in export case
Ting-Wei "Willy" Sun, a contractor linked to Super Micro, pleaded guilty last Thursday in U.S. District Court in Manhattan. The case involves servers equipped with advanced chips from Nvidia Corp in an alleged $2.5 billion scheme to export them to China.
Sun admitted to four charges: conspiring to violate U.S. export controls, smuggling, defrauding the U.S. government and obstructing justice. Prosecutors allege that Sun and two others tied to Super Micro diverted AI servers to China starting in 2024. The indictment described Sun as a broker and fixer who helped set up fake servers and misled U.S. Department of Commerce officials during a December 2025 inspection.
Co-founder Yih-Shyan "Wally" Liaw and Taiwan sales manager Ruei-Tsang "Steven" Chang were also indicted. Super Micro said it terminated Sun and cut ties with the other defendants earlier this year.
Regulatory restrictions on AI chips
The U.S. restricts sales of advanced AI chips to China on national security grounds. Those restrictions cover Nvidia’s B200, H100 and H200 graphics processing units, as well as servers equipped with these chips. The shipments allegedly violated these export restrictions.
Technical analysis and market context
From a trend perspective, SMCI is trading 19.2% below its 20-day SMA ($41.09) and 14% below its 50-day SMA ($38.58), keeping the near-term posture tilted bearish despite longer-term uptrend signals still on the chart. It is also 6.1% below the 100-day SMA ($35.37), but remains 2.3% above the 200-day SMA ($32.45), putting the stock in a critical zone between long-term support and short-term downtrend pressure.
The bigger-picture backdrop is mixed: the Golden Cross in August (50-day SMA above the 200-day SMA) remains a constructive longer-term feature, but the more recent MACD bearish cross in February aligns with the stock’s inability to hold above its faster averages. Traders will likely treat the October swing high as an overhead reference point, especially after the stock broke below support in August and has been working to rebuild its base since the July swing low.
- Key Resistance: $39.50, a nearby rebound ceiling that lines up with overhead congestion and sits close to the 50-day moving-average area
- Key Support: $29.50, a nearby floor where buyers previously stepped in, and a level that matters if price loses the 200-day SMA area
