POWL · PEAD ↓ 15

Powell Industries reported Q3 FY2026 EPS of $1.42 on 2026-08-03, missing the $1.49 consensus by $0.07 (-4.7%); no prior-year comparable available in the current data feed.

Print-day reaction was +5.3% versus the prior close, an immediate pop that initially appeared to absorb the EPS miss. The overnight gap, however, told a different story: POWL opened the next session -12.7% below the T+0 close, erasing the entire print-day gain and then some. Over the subsequent two trading days (T+1 close through T+3 close) price drifted an additional -1.9%, with no recovery materialising. Cumulative abnormal return of -3.5% versus SPY.US puts this in PEAD short territory — the drift reverses and overwhelms the initial reaction; per the documented pattern, the read holds through 2026-10-29.
