News reactions, by sector
The typical Healthcare name's news reactions span 2.47pp — 3.9x the typical Financial Services name's 0.63pp. Measured across 7,771 names in eleven sectors. Sector membership is CURRENT, not point-in-time: a name is counted where it sits today, including for reactions measured three years ago. Every measured ticker →
Sectors differ by how far names move, not which way.
No sector median reaction is published on this site, and this table is why: the middle name of every one of these sectors has a median 30-minute reaction of almost exactly zero, so ranking sectors by direction would print the same number eleven times. Width is the column that actually separates them — and it separates them by 3.9x.

Last 3 years, pulled 2026-09-21. Reaction = percent move vs. the price at the news timestamp. Every number here is a cross-section over NAMES, one vote each: a name with 2,000 measured events counts the same as one with 40, and none of these are pooled event medians. “Middle 50%” is the median name’s own p75−p25 at 30 minutes; “% positive” is the median name’s share of events that closed up; “Flat” counts names whose median 30-minute reaction is exactly 0.00%.
