Delisting is more than a corporate obituary—it is the market’s quiet, relentless act of natural selection. Each removal pinpoints the precise moment when strategy, governance, or timing fatally misaligned. By autopsying these “extinct” companies we obtain a reverse roadmap. Translate their terminal errors into early-warning signals and we can exit, pivot, or regulate long before the same gravity pulls us over the cliff. Elimination, in short, is information; our task is to harvest it before the next species—or stock—arrives at the edge.
