First displayed source row from Disclosed positions. The full bounded history and coverage notes remain below.

The displayed observation date is 2026-06-30 and its public availability date is 2026-07-29. Subtracting those calendar dates gives 29 days of disclosure lag. Historical public research can use the record from the availability date, rather than backdating knowledge to the observation date. The calendar-day difference does not assert an intraday publication time.

Read the amount together with its Unit and Option columns. A reported put or call position is not an option premium paid, and a quarterly holding is not a purchase made on its public filing date. Check every accession in the effective amendment lineage below: a retained holding can originate in an earlier filing rather than the latest linked amendment.

Open the linked original receipts to verify the row, then inspect a second record before drawing a pattern. This public filing observation supplies source evidence, not a completed copy-trading return.

How amendments affect these holdings

This view uses 1 effective filing version(s). A restatement replaces the previous book; a new-holdings amendment adds positions. 0 positions lack a resolved ticker and 0 positions are put or call entries.

The displayed holdings combine the effective filing versions listed here. The latest receipt linked below identifies the current projection version; it is not proof that every retained holding originated in that latest amendment. Inspect all effective accessions when verifying a position's source.

A 13F is a delayed quarterly snapshot of disclosed holdings. It is not a complete trade ledger and does not reveal every position in a manager's portfolio. Option values refer to the reported underlying position rather than a traded option premium.

Quarter end and public filing date

Use the filing's public availability date when constructing a historical observation. The quarter-end report period is earlier and cannot be substituted for when the public learned the holdings.
