% of shares outstanding is not shown for USCL: this is a fund line, and we hold no cover-page share count for it at any quarter — a fund's shares outstanding move with creations and redemptions rather than with issuance and buybacks, and it is not the SEC cover-page count this percentage is defined against. The figure is withheld rather than computed against a count that does not exist. Holder share counts are shown as filed.
Crowding percentile withheld — no market cap for USCL in the served universe — the cohort is size-matched, and an unmatched percentile would compare a micro-cap register to a mega-cap one.

Rows rank by the value each filer reported — 13F filers price their own positions, so a holder with fewer shares can rank just above one with more.

Shares reported each quarter by the largest current holders. Green = added vs the prior filing, red = trimmed, grey = roughly held; a dash is a quarter with no 13F on file (a gap is skipped, not read as an exit). 13F is filed up to 45 days after quarter-end. Up to 40 quarters (10 years) available — use the selector above.
Holder count only — too few computable %-of-shares-outstanding quarters for a % pane. Line breaks are quarters with no 13F record, never interpolated.

The 2025-Q4 register is as-filed in ITS OWN share basis; every count below was rebased into the 2026-Q1 basis (no split in between, factor 1). Dollar figures value the SHARE delta at one price — the 2026-03-31 close — rather than differencing two filings' own reported values, which would mix the quarter's price move into the trade figure.
13Fs disclose LONG US-listed positions only — shorts, most derivatives, bonds and non-US listings are invisible here, and a filer's quarter-over-quarter change is not necessarily a trade (index rebalances, in-kind transfers and entity successions all read as flow).
