Schedule 13D/13G stakes
Stakes of 5% or more disclosed on Schedule 13D or 13G, each on the filer's latest filing for the security. These are event-dated stakes, not the quarter-end 13F portfolio below.
| Company | Schedule | Event date | Filed | Shares | % of class | Status |
|---|---|---|---|---|---|---|
| XPRO Expro Ltd | 13D/A | Apr 17, 2026 | 7mo | 11,961,960 | 10.5% | Current |
| EBS Emergent BioSolutions Inc. | 13G | Sep 30, 2024 | 1y | 3,613,338 | 6.39% | Unconfirmed since Sep 30, 2024 |
A 13D or 13G stays in force until its filer amends it and no amendment is due without a material change, so a stake with no filing in 24 months reads unconfirmed, never sold. An amendment reporting under 5% ends the filer's duty to amend, not necessarily the holding. Shares are restated onto today's split basis. Show 1 exited, below-5% or retired stake
Portfolio style
Measured from the filed 13F common-share book for Jun 30, 2026, never from the firm's own description.
Closest benchmark: the Russell 2000 as of 2026-06-30, active share 99.8%; sector active share 76.8% against the combined 13F book's sector weights.
Over time 26 measured quarters
How the bands are measured
Style bands measure the filed 13F common-share book each closed quarter, tested in this order. Unknown: under $10,000,000 of valued equity or 5 stocks. Index-like (100+ stocks): active share of 20% or less against the closest benchmark, which is the S&P 500, S&P MidCap 400, S&P SmallCap 600, Russell 1000, Russell 2000, Nasdaq-100 or Dow Jones Industrial Average (weighted by an index-tracking fund's reported holdings or the index's constituents nearest the quarter end, over the names resolved to companies, and only when those are 90%+ of its weight) or every 13F filer's combined book, or index series holding 80%+ of the registered fund assets it advises (N-CEN) and equal to 50%+ of its book. Systematic-like: 500+ stocks, 100%+ annual turnover and a top 10 weight of 25% or less. Concentrated: a top 10 weight of 60%+ or 12 or fewer effective positions. Diversified active: none of these. Turnover is the smaller of buys and sells over average equity value, summed over four quarters: low under 30%, high 100%+. Horizon is the value-weighted number of quarters each position has been held: short under 4, long 12+.

Covers the securities this platform tracks: U.S.-listed common stock and the put/call positions reported on it. A 13F can also report security types outside that coverage — preferred shares, bonds, warrants, untracked share classes — so the filing's own declared total can exceed the figures above. The source filing is linked at the top of this table.
