📈
Buying streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds added NMM than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.

💰
Value +20% but shares only +3% — price-driven
Last quarter: the total dollar value of institutional holdings rose +20%, but actual share count only changed +3%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
📈
Growing discovery — still being found
11 → 3 → 11 → 12 → 15 new funds/Q
New funds entering each quarter: 3 → 11 → 12 → 15. A growing number of institutions are discovering NMM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

■ 59% veterans
■ 21% 1-2yr
■ 20% new
Of 81 current holders: 48 (59%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.
📋
Smaller funds dominant — 12% AUM from top-100
12% from top-100 AUM funds
9 of 70 holders rank in the top 100 by AUM, but together hold only 12% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
Exit risk score 2.9/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
