Estimate. 13F holdings are quarter-lagged, so the clone rebalances about 45 days after each period end — when the filing becomes public — and it excludes option and short positions. It tracks 68% of reported value on average across 12 quarters.OCONNOR, A Distinct Business Unit of UBS ASSET MANAGEMENT AMERICAS (LLC) has stopped filing, so the simulation ends in Jul 2026 — where its last reported portfolio went stale — rather than trading that portfolio forward to today. Past performance does not predict future results.

Covers the securities this platform tracks: U.S.-listed common stock and the put/call positions reported on it. A 13F can also report security types outside that coverage — preferred shares, bonds, warrants, untracked share classes — so the filing's own declared total can exceed the figures above. The source filing is linked at the top of this table.
