O'Rourke & Co. Discloses Q1 2026 Portfolio in 13F Filing

O'Rourke & Company's quarterly portfolio update was disclosed in a Form 13F filing with the U.S. Securities and Exchange Commission on May 14, 2026. The report details the firm's U.S. equity holdings as of March 31, 2026, a mandatory disclosure for institutional investment managers controlling over $100 million in qualifying assets. This filing provides a snapshot of the firm's public equity positioning at the end of the first quarter, offering a glimpse into its market strategy.

What is a Form 13F Filing?

A Form 13F is a quarterly report required by the SEC for institutional managers that exercise investment discretion over at least $100 million in specific securities. These securities, known as Section 13(f) securities, generally include U.S. exchange-traded stocks, shares of closed-end investment companies, and shares of exchange-traded funds (ETFs). The requirement was established in 1975 to increase the transparency of large investors' holdings.

The filing lists the name of the security, the number of shares held, and the total market value of those shares at the end of the quarter. This data allows regulators, competitors, and the public to see the long positions held by significant market participants. It does not, however, include all asset classes or trading strategies.

How Do Investors Use 13F Data?

Market participants analyze 13F filings to track the movements of prominent investors and identify broader market trends. By aggregating data from hundreds of funds, analysts can gauge institutional sentiment toward specific stocks or entire sectors. A significant increase in a stock's ownership across many funds can signal growing conviction from professional managers.

Investors also compare a firm's latest filing to previous ones, such as the report for the quarter ending December 31, 2025. This sequential analysis reveals new positions, exited stakes, and changes in the size of existing holdings. Such changes can highlight a manager's reaction to market events or a shift in their investment thesis for a particular company.

What Are the Key Limitations of 13F Filings?

The most significant limitation of a 13F filing is its time lag. The reports are due within 45 days after the end of a calendar quarter. This means the data for the period ending March 31 is not public until as late as mid-May. A fund's positions could have changed substantially during those six weeks, making the information dated upon release.

the 13F report presents an incomplete picture of a firm's total portfolio. It only discloses long positions in U.S. equities and certain other securities. It does not reveal short positions, which are used to bet against a stock, nor does it include holdings in bonds, commodities, currencies, or private equity holdings. Cash levels and derivative positions are also excluded, obscuring a manager's overall risk exposure.

O'Rourke & Company's Filing in Context

O'Rourke & Company's May 14th filing reflects its portfolio decisions made during the first quarter of 2026, a period with its own distinct market dynamics. Analysts reviewing the document will assess how the firm's holdings performed relative to major indices like the S&P 500 during that three-month window. The filing provides a baseline for understanding the firm's starting point for the second quarter.

For external observers, the value of a single 13F is often found in its contribution to a longer-term trend analysis. By examining O'Rourke & Company's filings over several years, one can better understand its investment philosophy and identify core long-term holdings. This historical view helps separate strategic, high-conviction bets from more tactical, short-term adjustments to its portfolio.

Q: Does a 13F show a fund's entire portfolio?

A: No. It specifically excludes short positions, options, futures, bonds, and non-U.S. traded securities. It also omits cash holdings, providing an incomplete view of a manager's total asset allocation and risk management strategy. The filing is a focused disclosure on long U.S. equity positions, not a complete financial statement.

Q: How often are 13F forms filed?

A: These forms are filed quarterly. Investment managers must submit their 13F report to the SEC within 45 days after the end of each calendar quarter. This means filings for the period ending March 31 are due by May 15, for June 30 by August 14, for September 30 by November 14, and for December 31 by February 14.

Bottom Line

O'Rourke & Co.'s latest 13F offers a valuable but delayed snapshot of its Q1 2026 U.S. equity positions.
