IDXX · PEAD ↑ 80

IDEXX Laboratories reported Q3 2026 EPS of $3.98 on 2026-11-02, beating the $3.71 consensus by $0.27 (+7.3%).

Print-day reaction was +21.8% versus the prior close — a decisive gap-and-hold on the earnings beat. The overnight session saw a modest fade of -1.4%, giving back a sliver of the initial surge without signalling a broader reversal. Over the following two trading days (T+1 through T+3), the stock drifted -0.2%, essentially flat — the initial move held without meaningful extension or give-back. Cumulative abnormal return of +24.7% versus SPY.US places this firmly in PEAD long territory; the documented drift pattern is tracked through the holding window end of 2027-01-28.
