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. Captured split ratios restate closes onto one basis; only an unusable ratio can exclude earlier closes for that listing. It tracks 100% of reported value on average across 9 quarters.Grassi Investment Management has stopped filing, so the simulation ends in Jan 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.
