What it checks

When WSB chatter accelerates from quiet to noisy, the stock drifts up for a week. When chatter fades, it mean-reverts.

Mechanism

Acceleration of retail attention (7d MA / 30d MA mention ratio) predicts 5-10 day continuation; decay predicts mean-reversion.

No production champion data for this family yet. Stats appear once the discovery pipeline promotes at least one strategy with this family tag.

Signal rule

long when 7d/30d mention ratio > 1.5; short when < 0.5; hold 5/10 days
