    Question

    Citadel increases AbbVie stake over 500% amid institutional yield rotation

    Direct answer

    Quarterly portfolio disclosures show Ken Griffin's Citadel expanded its position in AbbVie by more than 500% in Q2 2026. The substantial increase aligns with institutional rebalancing toward defensive cash generation. AbbVie advanced 1.78% to $261.70 during Monday's session, outperforming the benchmark S&P 500. The pharmaceutical group's 2.6% yield and 50-year dividend growth record attract capital seeking shelter from tech volatility.
