    JUSTIFIEDCONFIDENCE4/5

    Cognex is down 15.7% on the day and another 7.84% in the last five minutes after reporting quarterly results. The earnings release is the concrete catalyst, while the dividend announcement is not material enough to explain the move.

    WHYA 15.7% decline is large, but it is proportionate to a material quarterly-results reaction rather than an unsupported headline or financing event.
