In plain terms

When a company files an 8-K announcing a major restructuring or plant closure, the bad news isn't fully priced on day one — short for two months while the operating weakness leaks out.

How it works

8-K Item 2.05 (Costs Associated with Exit or Disposal Activities) flags material restructurings, plant closures, asset write-downs, and discontinued operations. House hypothesis: the market under-reacts at filing and the underlying operating weakness leaks out over ~60d. Item 2.05 was created by the 2004 Form 8-K amendments (effective 2004-08-23), so no earlier paper can study it directly; closest published support is Atiase-Platt-Tse 2004 (restructuring charges, mixed post-restructuring performance).

Expected edge

Reported return: none published; ~-4% over 60d is an internal house target validated only by our own harness
Tested over: T+1 to T+90d

House hypothesis (~-4% over 60d target), internal-harness-validated only. Atiase-Platt-Tse 2004 documents restructuring charges with mixed post-restructuring operating performance; no published paper estimates post-8-K-Item-2.05 return drift.
