Clone Performance
Feb 2025–Sep 2026 · vs SPYHypothetical 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.
Not a measure of this manager's performance.
Most of DIADEMA PARTNERS LP's reported book is option positions, which a stock-only clone
cannot replicate. The figures below are the return of the
36% that is ordinary stock — as little as
28% in one quarter — so a manager whose options
thesis lost money can still show a large gain here.

Max drawdown
−20.9%
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 36% 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.
