Holdings as of the 2026-Q1 13F-HR filing. 13F is disclosed up to 45 days after quarter-end.
What a 13F does — and does not — show
These figures come from Form 13F, a quarterly filing that large US institutional managers must submit to the SEC. It is a useful window, but a partial and lagged one, so read it carefully:
- It is a snapshot, up to 45 days old. A 13F shows what a manager held on the last day of a quarter, filed up to 45 days later — the fund may have traded since.
- Long US-listed stocks only. It excludes short positions, cash, bonds, most derivatives, and non-US or private holdings, so it is not the fund’s whole portfolio.
- Reported 13F value is not assets under management. Every share and concentration figure below is a percentage of the reported 13F value only — not the firm’s total assets.
- It describes, it does not recommend. A large or long-held position is not an endorsement, and none of this is investment advice.

How this filer invests
Reproducible measures computed from the positions in this filer’s own 13F filings — not from any outside estimate.
How concentrated the book is
Across 85 reported positions. Shares are of reported 13F value (long US-listed equity), which is not the firm’s total assets. The concentration index (HHI) is the sum of each position’s squared weight — higher means a book concentrated in fewer names.
How much the book turned over
Between the 2025-Q4 and 2026-Q1 filings, on the stable identity of each holding (share classes combined). New positions and exits are counted by presence; adds and trims by reported value, so a stock split does not read as a change.
Long-term holdings vs. higher turnover
Of its 20 largest reported positions, 8 have appeared in its 5 most recent consecutive quarterly filings (more than a year), and 12 are more recent. This filer holds a mix of longer-term and more recently established large positions.
Notable sizing changes among its long-held positions:
- GOOGL — share count increased 1538%
- TVTX — share count reduced 46%
- CPRX — share count reduced 36%
Directional only, measured over the filer’s largest reported positions across the quarters we track. 13F is a quarter-end snapshot, so a name can be held continuously yet slip in and out of the largest positions; this is a starting question, not a verdict.
Quarter-over-quarter changes
What changed between the 2025-Q4 and 2026-Q1 13F filings. New positions and exits reflect the tracked snapshot; adds and trims are measured on reported value (split-invariant), and moves under $0.25M are omitted as noise.
Between the 2025-Q4 and 2026-Q1 filings, this filer opened its largest new position in IOVA, fully exited CLMT, added most to AGIO, and trimmed APO the most. This describes what the 13F reported — not a recommendation.

About 13F filings
A Form 13F is a quarterly disclosure that institutional investment managers with over $100 million in US-listed equities must file with the SEC. In plain English: it is a snapshot of the long stock positions a fund held at the end of a quarter. It is filed up to 45 days after quarter-end, so it is backward-looking — the manager may have traded since — and it covers long US-listed equities only, not short positions, cash, or private holdings. Reading a 13F tells you what a manager owned, not whether you should own it.
