MTech Acquisition A (ABTC) and Aiai Holdings Corp (AIAI) dropped 9.85% and 12.21%, respectively.
Across market caps, the session showed a mix of earnings-driven responses, analyst actions and other company-specific developments moving share prices. Some companies cited positive results yet still saw share declines, illustrating how outcomes and market reactions can diverge within a single trading day.
