    JUSTIFIEDCONFIDENCE4/5

    AIOK is up 12.0% pre-market after its CEO reported buying 130,000 shares at an average price of $8.15. The insider purchase is a concrete bullish signal, and the 12% move is proportionate to that disclosure rather than an extreme reaction.

    WHYUp 12% on a disclosed 130,000-share CEO purchase is a meaningful but proportionate response to insider buying, with no financing indicated.
