AI Holders Summary · Q2 2026

Centene's biggest holders spent this quarter selling, even as a price rally pushed nearly every position's dollar value sharply higher. Assenagon Asset Management (flagged quasi_passive) cut shares 2.9%, Scharf Investments cut 4.0%, Ninety One UK cut 15.6% (1,791,325 to 1,511,766 shares, -$17.9 million in flow terms — the largest real sale in the table), and Wedge Capital Management cut a sharp 34.7% (746,025 to 487,090 shares, -$16.6 million). All four show negative share-flow dollars despite positive raw dollar-value changes, meaning the rally masked real, deliberate reductions in share count. Swedbank AB took the opposite side, adding a genuine 23.1% to its stake (1,028,386 to 1,266,223 shares, +$15.3 million) — real buying into the same strength the other four were selling into.

One large holder bought into the same rally

Swedbank AB took the opposite position: a genuine 23.1% increase in shares (1,028,386 to 1,266,223), a real $15.3 million addition — buying into exactly the strength that Assenagon, Scharf, Ninety One UK, and Wedge Capital were selling into. Wealth Enhancement Advisory Services made a smaller but similarly genuine add, up 12.9%.
