HDB · PEAD ↓ 18

HDFC Bank reported Q2 FY2027 results on 2026-10-16; consensus EPS was $0.40 (actual not yet in our feed).

Print-day reaction was +1.3% versus the prior close of $23.53, with the stock ticking modestly higher to close at $23.84 on the event date. The overnight gap, however, told a sharply different story: the T+1 open came in at $22.70, a gap down of –4.8% from the prior close, erasing the initial pop and then some. Over the following two trading days the drift continued lower, shedding an additional –1.8% from T+1 close to T+3 close of $22.67, confirming no recovery. Cumulative abnormal return of –3.8% versus SPY marks this as PEAD short territory; the drift reverses and overwhelms the initial reaction, with the holding window running through 2027-01-13.
