Smart Money Signals — NYXH

Based on 33 hedge funds · latest filing: 2026 Q1 · updated quarterly

➡️

No change last quarter

last 6Q

The number of hedge funds holding this stock didn't change last quarter. Neither a buying nor selling signal on its own — watch the next quarter for direction.

🏔️

At the ownership peak (100% of max)

100% of all-time peak

33 hedge funds hold NYXH right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.

🚀

Fast accumulation — +27% more funds vs a year ago

fund count last 6Q

+7 new funds entered over the past year (+27% 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 sellers than buyers — 48% buying

11 buying12 selling

Last quarter: 12 funds reduced or exited vs 11 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.

➡️

Steady new buyers — ~6 new funds per quarter

new funds entering per quarter

Funds opening this position for the first time: 8 → 6 → 4 → 6. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.

🔄

Mostly new holders — 39% entered in last year

■ 24% conviction (2yr+) ■ 36% medium ■ 39% new

Only 8 funds (24%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.

💎

Buying through price weakness — shares -3%, value -38%

Value

-38%

-2%

Last quarter: funds added -3% more shares while total portfolio value only changed -38%. 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

5 → 8 → 6 → 4 → 6 new funds/Q

New funds entering each quarter: 8 → 6 → 4 → 6. NYXH is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.

📊

Mixed cohorts — 18% veterans, 45% new entrants

■ 18% veterans ■ 36% 1-2yr ■ 45% new

Of 33 current holders: 6 (18%) held 2+ years, 12 held 1–2 years, 15 (45%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.

📋

Smaller funds dominant — 4% AUM from top-100

4% from top-100 AUM funds

7 of 33 holders rank in the top 100 by AUM, but together hold only 4% of total institutional value. The stock is held primarily by smaller and mid-sized funds.

4.4

out of 10

Moderate Exit Risk

Exit risk score 4.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
