Buying streak — 4 quarters in a row
For 4 consecutive quarters, more hedge funds added KPTI 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.
🔻
Below peak — only 65% of 3.0Y high
65% of all-time peak
Only 83 funds hold KPTI today versus a peak of 128 funds at 2023 Q2 — just 65% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
🚀
Fast accumulation — +66% more funds vs a year ago
fund count last 6Q
+33 new funds entered over the past year (+66% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟢
More buyers than sellers — 71% buying
63 buying26 selling
Last quarter: 63 funds were net buyers (29 opened a brand new position + 34 added to an existing one). Only 26 were sellers (10 trimmed + 16 sold completely). A clear majority buying is a strong confirmation signal.

■ 59% conviction (2yr+)
■ 19% medium
■ 22% new

💎
Buying through price weakness — shares +170%, value -64%
Last quarter: funds added +170% more shares while total portfolio value only changed -64%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
🚀
Acceleration phase — new buyers rushing in
5 → 11 → 8 → 24 → 29 new funds/Q
New funds entering each quarter: 11 → 8 → 24 → 29. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🏛️
Veteran-anchored — 71% veterans vs 20% newcomers
■ 71% veterans
■ 9% 1-2yr
■ 20% new
Entry-cohort mix of 100 holders: 71 (71%) are 2+ year veterans, 9 entered 1–2 years ago, and 20 (20%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
📋
Smaller funds dominant — 13% AUM from top-100
13% from top-100 AUM funds
19 of 77 holders rank in the top 100 by AUM, but together hold only 13% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
Exit risk score 2.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
