A 13F shows the portfolio at quarter-end and is filed up to 45 days later: these are not real-time positions and they may have changed.

This 13F omits positions for which the manager requested confidential treatment from the SEC: the portfolio may be incomplete until they are disclosed.

What it reported after the quarter end (Q2 2026)

The 13F shows the portfolio as of Jun 30, 2026. Since then Weiss Asset Management 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.

What changed this quarter

509 positions with a change (368 new, 66 added to, 75 trimmed); also, 25 entered through an IPO, 5 entered through a spin-off. 12 are listed here: those of 0.5 points of the portfolio or more (up to 12).

It started trading this quarter: it appears in a 13F for the first time. The filing does not say whether the manager already held it before the listing, so it is not counted as a purchase.

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.

13F filings with amendments or confidential positions

Declared options (11)

Besides stocks, Weiss Asset Management declared 10 puts (they gain if the stock falls) and 1 call (they gain if it rises) with a notional of $617M. 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

Type not verified: we have not assigned a type because we found no document that is enough to tell. Most 13F filers are in this situation: we only review in depth those that meet the portfolio criteria.

Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; it turns over more than 50% of the portfolio per quarter. 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.
