Super Micro Computer is trading 4.16% down at $38.67 after renewed attention on a China-linked shareholder lawsuit. - It alleges undisclosed China-linked server sales and export-control weaknesses; criminal charges involve individuals connected to it. - Reuters said shareholders accused the company of concealing China sales violating U.S. export laws; technology strength has not offset the legal overhang. - After a 9.50% September 17 gain, profit-taking may amplify the impact; limited coverage means medium confidence, and allegations remain unproven.
