Based on 438 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their RGEN positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
📊

High ownership — 93% of 3.0Y peak

93% of all-time peak
438 funds currently hold this stock — 93% of the 3.0-year high of 472 funds (reached 2024 Q1). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
〰️

Stable — ownership unchanged year-over-year

fund count last 6Q
The number of hedge funds holding RGEN is almost the same as a year ago (-1 funds, 0% change). No significant rush to buy or sell — institutional backing is holding steady.
🟡

Slight buying edge — 50% buying

232 buying231 selling
Last quarter: 232 funds bought or added vs 231 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
⚠️

Fewer new buyers each quarter (-36 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 76 → 76 → 102 → 66. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒

■ 64% conviction (2yr+) ■ 18% medium ■ 18% new
281 out of 438 hedge funds have held RGEN for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.

Buying through price weakness — shares +5%, value -27%

Value
-27%
Shares
+5%
Last quarter: funds added +5% more shares while total portfolio value only changed -27%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈

65 → 76 → 76 → 102 → 66 new funds/Q
New funds entering each quarter: 76 → 76 → 102 → 66. A growing number of institutions are discovering RGEN each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

■ 71% veterans ■ 9% 1-2yr ■ 20% new
Of 446 current holders: 317 (71%) 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.
✅

39% from top-100 AUM funds
57 of 438 holders rank in the top 100 by AUM, accounting for 39% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
3.2
out of 10
Low Exit Risk
Exit risk score 3.2/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.
