What it reported after the quarter end (Q2 2026)

Declared options (1)
Besides stocks, Peconic Partners declared 1 put (they gain if the stock falls) with a notional of $523M. 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.
