Last 3 years, pulled 2026-08-31. Reaction = percent move vs. the price at the news timestamp. Counts and medians only. The rank under each event type orders every name measured for it by median 30-min reaction, most positive first — so a low rank on a downgrade means this name falls harder than most, not that it moves less. Names with an identical median share a rank; a name the cross-section does not carry shows no rank rather than a guessed one.
