What it reported after the quarter end (Q2 2026)

The 13F shows the portfolio as of Jun 30, 2026. Since then Berkley W R has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.

Plus 26 more, in its EDGAR filings.

What changed this quarter

185 positions with a change (6 new, 55 added to, 55 trimmed, 69 sold); also, 10 entered through an IPO, 8 exited through an acquisition or merger, 55 entered through a spin-off. 10 are listed here: those of 0.5 points of the portfolio or more (up to 12).

The figure on the right: for positions added to or trimmed, the change in the number of shares (%); for new and sold ones, the points of the portfolio moved (pp). Below, the portfolio weight before → after. Traded weight: what it bought or sold, excluding price effects.

Top holdings

“Since”: first quarter of the current run, unbroken until today. In the details, prices are the quarter-end prices of the quarters in which it added shares, per the 13F. The manager may have bought at any price within each quarter; the SEC only publishes the value at quarter end.

13F filings with amendments or confidential positions

Declared options (5)

Besides stocks, Berkley W R declared 5 puts (they gain if the stock falls) with a notional of $137M. The 13F reports the value of the underlying shares, not the premium paid, so these figures look large and are not added to the portfolio. Nor does it say whether the option is bought or written, or its strike or expiry: it may be a hedge.

Stakes above 5% (13D/13G)

Companies where this filer reported holding 5% or more of the shares. It is the figure from its latest filing on each one; history since December 2024.

How we classify it

Insurance holding, per its SEC filings (EDGAR) (high confidence).

The data, as reported: EDGAR: SIC 6331 Fire, Marine & Casualty Insurance; since 2023-10-10 it has filed 10-K, 10-Q, 13F-HR, N-PX, SC 13G, SCHEDULE 13D, SCHEDULE 13G (listed insurer)

The type comes from a rule applied to that data. If it looks wrong, tell us.

Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%; it is an insurer whose portfolio we have not reviewed by hand. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided

Managers of a similar size

A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
