Quarter flow (concentrated managers)

Change in managers (2 → 2): 0 opened · 0 exited = 0

Net flow in the quarter: +$586K (+23 K shares) · bought $586K and sold $0Shares concentrated managers added minus those they cut, valued at the 13F quarter-end implied price, not each trade's price. It is a different measure from the change in managers: the two can have opposite signs.

Accumulation: combined they have held more shares for 2 quarters in a row (1 added, 0 trimmed). It is the combined share count of those still holding it: one large buyer can outweigh many who trimmed.

The 10 13F filers with the most shares as of Jun 30, 2026, whatever their type (index firms usually come first). “Change”: shares added or cut versus the previous quarter, split-adjusted; “no data” = there is no comparable portfolio for the previous quarter (no filing, or a filing with its holdings under confidential treatment). “% of the company” only where shares outstanding are up to date. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.
