The breadth of active-manager accumulation (10 buyers vs 1 seller) signals a consensus that CHTR was undervalued at Q3 prices. Monitor upcoming Q4 earnings for fundamental confirmation — if the thesis was correct, the stock should have re-rated. The single large exit by Davenport & Co is an outlier and may reflect portfolio rebalancing rather than a negative view on CHTR.
Executive Summary
Ten institutional investors added to their CHTR positions in Q3 2026, with aggregate buying of $17.7M overwhelming a single $13.5M exit by Davenport & Co. The cluster is dominated by active asset managers, with Assenagon Asset Management nearly tripling its stake (+$16.7M), representing the bulk of net inflows. The 45-day reporting lag means these positions may have already been adjusted, but the breadth and conviction of the buying suggest a shared view that CHTR was undervalued at Q3-end levels.
