    JUSTIFIEDCONFIDENCE5/5

    CareDx is up 25.4% after reporting a major Q3 earnings and revenue beat and sharply raising FY2026 revenue and adjusted EBITDA guidance. The quantified outlook upgrade and profitability surprise provide a concrete fundamental catalyst for the move.

    WHYA 25.4% gain is substantial, but it is proportionate to a 180% EPS beat, a revenue beat, and a roughly 6% to 8% FY2026 revenue-guidance increase.
