These positions appear in the prior filing and not in the current filing. That does not prove when or how the position changed.

Form 13F generally covers reportable US securities and some option positions. It can omit cash, private assets, many derivatives, ordinary short sales, bonds, and foreign-only listings. The filing receipt, not an inferred total, defines this page's scope.
