Source: SEC Form 13F-HR 0001172661-26-003662, compared with the Q1 2026 report. 0 option rows are excluded from weights. Tickers map from CUSIP via OpenFIGI. Estimated returns weight each position’s next-quarter total return (Yahoo Finance adjusted closes) by its quarter-end value and assume no trades. Estimated cost averages daily adjusted closes in each quarter the share count rose, from Q3 2023 onward (* = held at the start of our data). Price is the latest close.

Important information

Form 13F data is delayed. Managers have up to 45 days after each calendar quarter to file, so holdings shown may have changed materially since the report date. 13F reports cover long positions in US-listed equities and certain other securities only; they exclude short positions, most non-US holdings, cash, bonds and private investments, and managers may request confidential treatment for some positions. Options rows are listed in filings but are not counted in the holdings and weights shown here.

Estimated holdings returns, estimated cost and high-conviction results are hypothetical calculations from quarter-end holdings and public prices, assuming no trades between reports. They are not the actual returns or costs of any fund or manager and do not reflect fees, trading, leverage, shorts or cash. Biographies are drawn from cited public sources. This page is for information only and is not individualized investment advice or a recommendation to buy or sell any security. Gulfstream Capital and its clients may hold positions in securities shown.
