% 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.
GetSignal pushes each new 13F to your phone as it is filed, with the positions that changed and the companies behind them. Free on iOS and Android.

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.

How current is this?
This is the Q2 2026 filing, covering positions held on Jun 30, 2026 and filed with the SEC on Aug 14, 2026. A 13F is due 45 days after the quarter ends, so the most recent filing is always at least six weeks behind the market, and the manager may have changed the book since.
