Smart Money Signals — ATYR

Based on 84 hedge funds · latest filing: 2025 Q4 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their ATYR 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 — 75% of 3.0Y peak

75% of all-time peak
84 funds currently hold this stock — 75% of the 3.0-year high of 112 funds (reached 2025 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📶

Steady growth — +11% more funds vs a year ago

fund count last 6Q
+8 new funds entered over the past year (+11% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🔴

Heavy selling pressure — only 35% buying

40 buying73 selling
Last quarter: 73 funds sold vs only 40 buyers. This is widespread institutional distribution — not a few funds rebalancing, but a broad exit. High conviction bearish signal.
⚠️

Fewer new buyers each quarter (-25 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 26 → 52 → 42 → 17. 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.
📌

Mixed — 35% long-term, 43% new

■ 35% conviction (2yr+) ■ 23% medium ■ 43% new
Of the 84 current holders: 29 (35%) held >2 years, 19 held 1–2 years, and 36 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
💰

Price up while funds trimmed (-4% value, -23% shares)

Value
-4%
Shares
-22%
Last quarter: total value of institutional ATYR holdings rose -4% even though funds reduced share count by 23%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
📊

Peak discovery — momentum slowing

29 → 26 → 52 → 42 → 17 new funds/Q
New funds entering each quarter: 26 → 52 → 42 → 17. ATYR is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️

Deep conviction — 47% of holders stayed 2+ years

■ 47% veterans ■ 6% 1-2yr ■ 48% new
Of 90 current holders: 42 (47%) 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.
🏆

Elite ownership — 42% AUM from top-100 funds

42% from top-100 AUM funds
26 of 84 holders are among the 100 largest funds by AUM, controlling 42% of total institutional value in ATYR. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.7
out of 10
Low Exit Risk
Exit risk score 3.7/10 — 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.
