How we classify it
Investment firm, per its Form ADV of Mar 31, 2026 (high confidence).
The data, as reported: MANGROVE PARTNERS (CRD 162296): 7.B private funds: 1 hedge (gross assets $2.7 bn); 5.D assets by client type: pooled vehicles 99% (of $2.7 bn)
The type comes from a rule applied to that data. If it looks wrong, tell us.
Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided
Similar managers by type and size
Same type of filer and a 13F portfolio value between a third and three times this one. It is not a comparison of what they hold.
