MDB · PEAD ↑ 100

MongoDB reported Q1 FY2027 EPS of $1.32 on 2026-05-28, beating the $1.18 consensus by $0.14 (+11.9%).

Print-day reaction was +10.6% versus the prior close, a sharp gap-and-hold into the close that left MDB well above its pre-earnings range. The overnight gap to T+1 open extended a further +7.6%, signalling no after-hours fade and sustained buy-side demand. Over the following two trading sessions the stock drifted an additional +18.7%, with no meaningful give-back — an unusually clean continuation. Cumulative abnormal return of +34.1% versus SPY.US over the three-day window places this firmly in PEAD long territory; the documented drift pattern holds the read through 2026-08-25.
