ISHARES TR, News and Bitcoin Infrastructure Acquisition are filed on more than one line (share classes, or several funds under one trust name), so they're left out of the new, added and reduced lists, and the change in shares shows as n/a for ISHARES TR and Bitcoin Infrastructure Acquisition. A row that joins share classes shows their changes added together.

13F filings arrive up to 45 days after quarter end and cover US-listed long positions only. A put or call line is the option the manager holds, valued at the shares it covers, not at what the option cost; it counts in the reported value and the weights, as the filing counts it. Positions may have changed since. This is observation data, not a recommendation.

What this data is

Fund holdings (13F) for Starboard Value

Institutional managers with more than $100 million in US equities file a Form 13F within 45 days of each quarter end, listing every long position they held on the last day of the quarter. The site follows a fixed set of 30 managers and turns each filing into a table: the position, its value, its weight in the portfolio and how the share count changed from the previous quarter.

13F data is old by the time it's public, up to 135 days from the trade in the worst case. It won't tell you what a manager did yesterday. It tells you what they own, what they've been building for several quarters, and what they exited.

This page follows Starboard Value only. The full list and the cross-market view live on the Fund holdings (13F) hub.

How to read it

The change column is the story. A position built over three quarters is conviction; a position that appeared and vanished was a trade.
Portfolio weight beats dollar value for comparing managers of different sizes.
Treat every 13F number as weeks old and read it for structure, not timing.

Analysis of what the data shows, not advice. XOOMAR does not recommend buying, selling or holding anything.
