Halts firing within an hour of breaking news
When breaking news fires within 30 minutes of a halt, another halt is 87% likely to fire — based on 68 historical breaking-news halt matches.
In plain English
News-driven halts behave fundamentally differently from technical halts. When a wire service publishes within an hour of a halt firing, the halt is typically a market reaction to the news rather than a momentum cascade. The directional persistence is dramatic: traders are pricing in a known catalyst, so the move continues until either the catalyst is fully digested or fresh information arrives. The Pattern Matcher splits halts into technical and news cohorts at scoring time so this signal is not diluted by the larger technical-halt population.
