Smart Money Signals — NEPH

Based on 27 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 NEPH 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 — 77% of 3.0Y peak

77% of all-time peak

27 funds currently hold this stock — 77% of the 3.0-year high of 35 funds (reached 2025 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.

🚀

Fast accumulation — +59% more funds vs a year ago

fund count last 6Q

+10 new funds entered over the past year (+59% 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.

🔴

Heavy selling pressure — only 31% buying

9 buying20 selling

Last quarter: 20 funds sold vs only 9 buyers. This is widespread institutional distribution — not a few funds rebalancing, but a broad exit. High conviction bearish signal.

⚠️

Fewer new buyers each quarter (-12 vs last Q)

new funds entering per quarter

Funds opening this position for the first time: 3 → 5 → 15 → 3. 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.

🔒

41% of holders stayed for 2+ years

■ 41% conviction (2yr+) ■ 26% medium ■ 33% new

11 out of 27 hedge funds have held NEPH 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 +1%, value -38%

Value

-38%

+1%

Last quarter: funds added +1% 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.

➡️

Steady discovery — ~3 new funds/quarter

1 → 3 → 5 → 15 → 3 new funds/Q

New funds entering each quarter: 3 → 5 → 15 → 3. Consistent flow of new institutional buyers without clear acceleration or slowdown.

🏛️

Deep conviction — 52% of holders stayed 2+ years

■ 52% veterans ■ 11% 1-2yr ■ 37% new

Of 27 current holders: 14 (52%) 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.

📋

Smaller funds dominant — 5% AUM from top-100

5% from top-100 AUM funds

9 of 27 holders rank in the top 100 by AUM, but together hold only 5% of total institutional value. The stock is held primarily by smaller and mid-sized funds.

4.8

out of 10

Moderate Exit Risk

Exit risk score 4.8/10 — 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.
