Schonfeld Reported 3 Put Lines. The Quarters Either Side: 60 and 129.

A $14.2bn manager reported three put lines for one quarter. I scanned all 8,400 filers who reported both quarters: two show this signature.

Schonfeld Strategic Advisors reported three put positions totalling $56,352,600 in its 13F for the quarter ended 31 March 2026, against a reported book of $14,211,293,816. The quarter before carried 60 put lines worth $1.310bn. The quarter after carried 129 worth $6.202bn. Inside the anomalous filing, the number of index and ETF put lines is zero, while the same document reports 21 index and ETF call lines worth $1.583bn.

The filing is on time, complete on its face, and reproduces its own declared totals to the dollar. I checked this morning and no amendment has been filed in the 93 days since. I scanned all 8,400 managers who filed original 13Fs for both quarters, and two of them show this signature. If you run any signal derived from 13F option composition, you ingested a 95% collapse in one manager’s put book, and nothing upstream of you was built to tell you whether it happened.
