Conviction holdings
Positions increased for 3+ consecutive quarters.
Share counts are as reported in 13F filings (not split-adjusted)
Top movers (QoQ)
Exited positions

Closed positions reflect 13F reporting changes; for index managers these are often mechanical (delisting, M&A, index rebalancing), not active decisions.
