Vanguard's new 5%+ stake is consistent with index fund rebalancing and is not a conviction signal. The cross-filing context shows Sachem Head Capital Management fully exited 21 days prior, which may offset any positive read-through from Vanguard's entry. Monitor for any further 13G amendments from Vanguard or additional institutional filings.
