Item 4 02 Restatement Short
In plain terms

How it works

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.
When a company quietly amends its charter or bylaws, it's often putting up takeover defenses or entrenching management — historically these moves predict ~3 months of underperformance.
When a company starts filing many more 8-Ks than usual, it's often because something bad is being staged — short the stock through the disclosure storm.
