TER · PEAD ↓ 79

Teradyne reported Q3 2026 EPS of $2.29 on 2026-10-27, beating the $2.04 consensus by $0.25 (+12.3%).

Print-day reaction was +4.8% versus the prior close, an unambiguous beat-driven pop on the day of the report. The overnight gap to T+1 open then reversed sharply, giving back -6.5% and erasing the entire earnings-day gain before the next session began. Over the following two trading days (T+1 close through T+3 close) the stock drifted a further -12.4%, a sustained and accelerating sell-off that overwhelmed the initial positive reaction. Cumulative abnormal return of -9.9% versus SPY.US places this squarely in PEAD short territory; the drift-reversal pattern signals the holding read runs through 2027-01-22.
