VICR · PEAD ↓ 48

Vicor reported Q3 2026 EPS of $1.33 on 2026-10-20, missing the $1.39 consensus by $0.06 (-4.3%).

Print-day reaction was +7.1% versus the prior close, a sharp initial move higher despite the EPS miss, as the market appeared to look through the shortfall. The overnight gap to T+1 open added another +3.1%, suggesting residual enthusiasm held into the after-hours session. Day 1–3 drift then reversed hard, with the stock falling -17.5% from the T+1 close to the T+3 close — a decisive fade that unwound the entire initial move and then some. Cumulative abnormal return of -6.8% versus SPY.US puts this in PEAD short territory; the drift-reversal pattern is the operative signal, with the holding window running through 2027-01-15.
