Baiya International is trading 61.9% higher at $2.21 on October 7, 2026, after a sharp after-hours spike and continued pre-market gains from its October 6 close of $1.36; no confirmed company announcement or event explains the move. - The latest located company news was its September 29 first-half fiscal 2026 results, which do not establish a direct cause for the surge. - The company’s newsroom lists no upcoming events. - Broader U.S. indexes closed higher, but those gains do not explain the unusually large individual-stock move.
