Quarter-to-quarter notes

Reported change, not a confirmed trade: this compares quarter-end reports filed up to 45 days later, and the position may since have changed. Amendments, corporate actions, and changes in reporting scope can also move these rows. Value change compares period-end reported values; for continuing rows it includes market price movement.

Newly reported by Point72 Asset Management, L.P., Sachem Head Capital Management LP.

Changes appear only where the prior quarter's validated report exists.
