📈
Buying streak — 2 quarters in a row
For 2 consecutive quarters, more hedge funds added IRWD 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.

📉

💎

■ 9% 1-2yr
■ 25% new

🏆
Elite ownership — 40% AUM from top-100 funds
40% from top-100 AUM funds
32 of 191 holders are among the 100 largest funds by AUM, controlling 40% of total institutional value in IRWD. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
