📈
Buying streak — 1 quarter in a row
For 1 consecutive quarter, more hedge funds added INMB 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.

High ownership — 85% of 3.0Y peak
85% of all-time peak

🟡

💎
Buying through price weakness — shares -2%, value -26%
Last quarter: funds added -2% more shares while total portfolio value only changed -26%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊
Peak discovery — momentum slowing
13 → 18 → 26 → 15 → 13 new funds/Q
New funds entering each quarter: 18 → 26 → 15 → 13. INMB is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.

■ 50% veterans
■ 18% 1-2yr
■ 32% new
Of 74 current holders: 37 (50%) 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.
🏆

48% from top-100 AUM funds
22 of 72 holders are among the 100 largest funds by AUM, controlling 48% of total institutional value in INMB. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
