What it reported after the quarter end (Q2 2026)

The 13F shows the portfolio as of Jun 30, 2026. Since then Peak6 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

1051 positions with a change (312 new, 187 added to, 265 trimmed, 287 sold); also, 15 entered through an IPO, 5 exited through an acquisition or merger, 1 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 (25)

Besides stocks, Peak6 declared 10 puts (they gain if the stock falls) and 15 calls (they gain if it rises) with a notional of $44.5 bn. 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

Not counted as a concentrated manager: it has fewer than 8 quarters of history; its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%; more than 20% is options; it is a bank or trading desk; its positions are usually hedges or inventory. 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.
