Cathie Wood runs ARK Investment Management LLC, a diversified book of 189 stocks worth $15.4B as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter they opened Space Exploration Techn-CL A and trimmed Tesla Inc. Their largest long position is Tesla Inc at 8% of the equity book.
ARK is the only book here that narrates itself daily. Research notes, trades disclosed nightly. That makes the 13F almost redundant, except for one thing: it standardizes the book into the same shape as everyone else's, so conviction can be compared side by side. Read it against the daily disclosures, not instead of them.
New buys still signal; exits still judge. And ARK's concentration cuts both ways. The focus that compounds in a mania draws down in a rotation. The 45-day lag applies to ARK too.

Use Arkolith to show Cathie Wood's latest 13F book, the biggest position changes this quarter, and the filing each one comes from.
Aggregated from SEC Form 13F filings (institutional long equity positions, reported quarterly, up to 45 days after quarter-end). Holdings are public domain, sourced to SEC EDGAR. The book totals, weighting, concentration and sectors are long equity only; disclosed put/call options are listed separately and excluded from those figures. Price-derived performance is withheld until the price-source policy and freshness gate are green. Every panel is one call to the Arkolith API & MCP server.
