In Q2 2026 it opened 11 new positions, added to 25, trimmed 2 and sold out of 12. At today's prices that book is up 2.7% since the quarter closed.

Can you see Optiver's cost basis or profit?
No. A 13F lists positions at quarter-end, not what was paid or when, and it excludes shorts and non-US holdings. This page shows each stock's price change since the quarter closed (the whole book as filed is +2.7%, with 100% of it priced) and since the position first appeared, which is a rough read and not their profit.
Where does this data come from?
- Holdings: Optiver's Form 13F-HR filings, listed on SEC EDGAR; the latest, filed Aug 12, 2026, is here. The Q2 2026 book was filed Aug 12, 2026.
- Prices and tickers: today's prices are from Finnhub, matched to each filing's securities with OpenFIGI; "since quarter-end" compares today's price with the price implied by the filing (value divided by shares).
- Limits: a 13F covers long US-listed positions only, up to 45 days after the quarter ends: no shorts, no cost basis, no trades inside the quarter. Read the Editorial Standards for how this site treats filings, and Form 13F in the glossary.
