STMicroelectronics N.V. (STM) by event type
STM moves most on analyst downgrades — a median of -0.10% at 30 minutes across 34 measured events. Each row is measured over the last three years and read against the price at its own news timestamp. Back to the STM overview →
How STM reacts across 4 measured event types.
| Event | Events | Median 30-min | % positive | Median to close |
|---|---|---|---|---|
| Analyst upgrades 1,064 of 2,717 | 48 | +0.10% | 56% | +0.43% |
| Analyst downgrades 1,694 of 2,603 | 34 | -0.10% | 29% | +0.15% |
| Rating reiterations 1,982 of 3,522 | 48 | -0.02% | 48% | +0.01% |
| Price-target cuts 418 of 1,527 | 12 | +0.09% | 58% | -0.13% |
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. 2 further classes were observed with fewer than 10 measured events and are not published.
