STAK is trading 5.0% down at $3.40 after a sharp reversal from its July 16 close of $3.58. This follows a significant surge yesterday driven by news of the company's planned U.S. subsidiary for modular gas-to-electricity generation systems aimed at AI data centers. The stock is also facing headwinds from a broader tech sector sell-off, with semiconductor and AI stocks under significant risk-off pressure.
