On August 5, Cognex declined 7.48% in after-hours trading, trading at $65.76/share, with turnover of approximately $2.15 million. The sell-off followed the company's release of Q2 earnings after market close.

Heading into the report, market consensus expected Q2 revenue of $293 million, representing 18.84% year-over-year growth, and adjusted EPS of $0.43, up 79.63% year-over-year. Expectations had been significantly elevated following a blowout Q1, in which Cognex posted revenue of $268.4 million versus the $246 million estimate and adjusted EPS of $0.34 versus the $0.25 consensus. The company also issued strong Q2 guidance of $280 million to $300 million in revenue and $0.40 to $0.44 in adjusted EPS, both well above analyst forecasts at the time.

The stock had already rallied over 5% ahead of the earnings release, reflecting the market's optimistic positioning. The after-hours pullback suggests Q2 results did not sufficiently exceed the elevated expectations that had already been priced into the stock following consecutive quarters of significant beats.
