The cluster is entirely passive/index-driven, not active manager conviction — Vanguard, BlackRock, and Fidelity likely increased due to index rebalancing or market-cap weighting changes, not a fundamental thesis. Monitor for any active manager 13D/G filings or insider buying to confirm genuine conviction.
