What it checks

When a company lists materially more discrete risks in its 10-K vs prior year, the stock tends to underperform over the next 3-6 months.

Mechanism

Distinct risk-factor count in 10-K Item 1A — disclosure-density measure — is a forward indicator of realized volatility and short-side returns when it rises sharply over baseline.

No production champion data for this family yet. Stats appear once the discovery pipeline promotes at least one strategy with this family tag, or once a multi-family blend that includes it earns a champion slot.

Signal rule
