Exact data and methodology

Axes scale independently; a crossing does not mean equal values. Weight uses each quarter's total reported non-derivative value. Same CUSIP; missing quarters are gaps, not zero. Revised history may include later disclosures.

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.
