How DBX reacts across 2 measured event types.
| Event | Events | Median 30-min | % positive | Median to close |
|---|---|---|---|---|
| Analyst downgrades 2,572 of 2,603 | 16 | -3.51% | 19% | -9.33% |

Last 3 years, pulled 2026-09-21. 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. 4 further classes were observed with fewer than 10 measured events and are not published.
