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 Clearline Capital LP's reported book is option positions, which a stock-only clone cannot replicate. The figures below are the return of the 69% that is ordinary stock — as little as 41% in one quarter — so a manager whose options thesis lost money can still show a large gain here.

SPY

+67.5%

Annualised alpha

-22.4%

Max drawdown

−42.1%

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 69% of reported value on average across 13 quarters. Past performance does not predict future results.
