Abstract: HSIL announced six immediate Connect ADDs and zero DELETEs, effective 8 Jun 2026. Three delayed ADDs remain outside this study pending stock splits. Our 4 May forecast called five of six ADDs correctly. Pre-announcement cohort return matched history, but stock dispersion was far wider than prior cycles. Opening-gap size should drive bridge-window entry.
