ATCO-A.ST · PEAD ↑ 81

Atlas Copco reported Q2 2026 EPS of 1.4789 on 2026-07-16, missing the 1.50 consensus by 1.41% — yet the market's price response told a notably different story.

Print-day reaction was +4.44% versus the prior close, a decisive move higher despite the modest EPS miss. The overnight gap to the T+1 open added a further +0.82%, signalling no fade in after-hours or pre-market trading. Over days 1 through 3, the stock drifted an additional +1.07%, sustaining the initial thrust rather than giving it back. Cumulative abnormal return of +6.61% versus SPY.US — which declined 0.86% over the same window — firmly places this in PEAD long territory; the documented drift pattern holds through 2026-10-13.
