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. Returns use comparable raw closes and exclude dividends. Returns are unavailable when a held security or benchmark crosses a captured split without a certified price basis; the requested window is not shortened to hide it. It tracks 100% of reported value on average across 7 quarters. 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.
