First halts with 30%+ down gaps
Stocks with extreme down halts (30%+ gap) continue in the same direction 70% of the time when they cascade — based on 236 historical matches.
In plain English
A 30%+ down gap on a first halt is a tail event — it tells you the stock has hit something fundamentally bad (deal break, dilution, fraud allegation, FDA rejection). When these halts cascade, they cascade in the same direction at rates that materially exceed the population baseline. Not every extreme-gap halt cascades, but those that do tend to keep going down for a reason: the market is still discovering the new equilibrium price.
