The initial HTML of this page carries its exact data as script#portfolio-data (JSON): values, units, scope, preview limits and SEC sources. Read it directly, no script or API key needed; script#research-access says what needs an account. This page lists 7 of 7 current positions (options included); totals and weights use the complete filing.

Without an account: the last 3 years, with the row caps stated on the page. A free account opens all history on file on these pages and the CSV of what a page shows. Rows beyond the caps and bulk retrieval go through the authenticated API / MCP.

Sources, coverage & how to read this data

Figures are as reported to the SEC and merged with later amendments where Akkru could match them. Preview limits apply to what is listed, not to the totals, which come from the complete reported data. Nothing is zero-filled: a missing quarter or month is shown as missing.

13F reports quarter-end long positions in securities traded on US exchanges, filed by managers holding at least $100 million of such securities; it is not the manager's full portfolio, not assets under management, and value changes are not returns. Weights use the reported total value as denominator. Option rows show notional value, not premium or net exposure. Amendments are merged into the quarter when Akkru could match them.
