1 position hidden — reported move looks larger than the position itself (data completeness check)

Exited positions

Includes corporate events (mergers, delistings) — not all exits are sells

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