Declared options (7)

Besides stocks, Holocene Advisors declared 7 calls (they gain if it rises) with a notional of $688M. 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: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided

Similar managers by type and size

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