Last 3 years, pulled 2026-09-21. Reaction = percent move vs. the price at the news timestamp. Ranked by measured events, most first — the bake caps a name’s count at 2,000, so names at the cap are ordered by symbol rather than by anything measured. Every number on this page 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.
