SOI.PA · PEAD ↓ 100

Soitec reported Q results on 2026-05-27 (after market close); consensus EPS was 0.66 — actuals are not yet in our feed.

Print-day reaction was −7.5% versus the prior close, a sharp move that broke the stock well below its pre-earnings range. The overnight gap to the T+1 open partially recovered, adding +3.7%, but failed to reclaim the losses. Over the subsequent two trading days (T+1 close through T+3 close), the drift turned deeply negative at −23.4%, erasing the overnight bounce and then some. Cumulative abnormal return of −12.8% versus SPY.US firmly places this in PEAD short territory; per the documented drift pattern, the read is held through 2026-08-24.
