% of 13F value is the position's value against the whole disclosed 13F value, so the rows shown here do not sum to 100% unless every position is listed. Calls and puts are shown as filed: most filers give Value as the notional value of the shares underneath, not money invested, but some give the premium paid, and some count contracts rather than shares. A Note is a convertible bond, which the filing sizes by its face amount rather than a share count.

A change is this filing measured against the one before it. Est. amount moved is the shares added or sold, priced at the Jun 30, 2026 close. An estimate: a 13F gives no trade prices or dates. For a sold-out position, its value at the previous quarter end. A put gains when the stock falls; a call gains when it rises. Option values are as filed, which for most filers is the notional value of the shares underneath.
