In plain terms

When a federal lawsuit naming a public company is filed in the categories that historically hurt the most (securities fraud, patent, antitrust), we go short for 1-6 months.

How it works

Federal court filings in nature_of_suit 850 (Securities), 830 (Patent), or 410 (Antitrust) naming a public company as a party predict -2% to -6% drift over 1-3 months. CourtListener RECAP free webhooks fire within minutes of new federal filings.
