Clone Performance

Nov 2024–Aug 2026 · vs SPY

Hypothetical growth of buying every stock this filer reported holding, rebalancing on each filing and indexed to the same start. Option positions cannot be bought this way and are left out.

+62.8%
SPY
+29.1%
Annualised alpha
+16.0%
Max drawdown
−39.0%

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 8 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.
