Clone Performance

Jul 2023–Jul 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.

Not a measure of this manager's performance. Most of Portman Square Capital LLP's reported book is option positions, which a stock-only clone cannot replicate. The figures below are the return of the 6% that is ordinary stock — as little as 2% in one quarter — so a manager whose options thesis lost money can still show a large gain here.

Cloned portfolio

+39.3%

SPY

+65.3%

Annualised alpha

-6.6%

Max drawdown

−26.2%

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 6% of reported value on average across 13 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.
