TSM · PEAD → 0

TSMC reported Q3 2026 EPS of $4.60 on 2026-10-15, beating the $4.45 consensus by $0.15 (+3.4%).

Print-day reaction was -1.8% versus the prior close, as the stock opened sharply lower despite the EPS beat and recovered only partially through the session. The overnight gap into T+1 extended the slide by a further -0.2%, with no meaningful after-hours recovery. Over days 1–3 the stock clawed back +3.0%, reversing the initial drop and nearly erasing the print-day loss — a drift that ran counter to the negative opening reaction. Cumulative abnormal return of -1.1% versus SPY.US sits within the ±3% neutral band; no durable PEAD signal is present, and the read expires 2027-01-12.
