STAK is trading at $1.10, down 5.98%, with no identified company-specific announcement explaining the September 28 decline. - The latest reported company item was a September 15 notice about shareholder meetings. - Broader markets are lower as oil rises amid stalled U.S.–Iran talks and Treasury yields climb, weighing on investor sentiment. This is a plausible context, but no direct link to STAK’s move has been identified.
