Clone Performance
Jul 2023–Jul 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 CSS LLC/IL's reported book is option positions, which a stock-only clone
cannot replicate. The figures below are the return of the
54% that is ordinary stock — as little as
40% in one quarter — so a manager whose options
thesis lost money can still show a large gain here.

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 54% of reported value on average across 13 quarters. Past performance does not predict future results.
