Smart Money Signals — NEPH

Based on 33 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q

For 1 consecutive quarter, more hedge funds added NEPH 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.

📊

High ownership — 94% of 3.0Y peak

94% of all-time peak

33 funds currently hold this stock — 94% 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 — +74% more funds vs a year ago

fund count last 6Q

+14 new funds entered over the past year (+74% 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.

🟡

Slight buying edge — 58% buying

14 buying10 selling

Last quarter: 14 funds bought or added vs 10 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.

➡️

Steady new buyers — ~7 new funds per quarter

new funds entering per quarter

Funds opening this position for the first time: 5 → 15 → 3 → 7. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.

📌

Mixed — 36% long-term, 45% new

■ 36% conviction (2yr+) ■ 18% medium ■ 45% new

Of the 33 current holders: 12 (36%) held >2 years, 6 held 1–2 years, and 15 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 (+19% value, -1% shares)

Value

+18%

-1%

Last quarter: total value of institutional NEPH holdings rose +19% even though funds reduced share count by 1%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.

⚠️

Saturation — most institutions already know this story

3 → 5 → 15 → 3 → 7 new funds/Q

New funds entering each quarter: 5 → 15 → 3 → 7. Far fewer institutions are entering now vs. a year ago. When the pool of potential new buyers shrinks this fast, future price support from institutional inflows weakens significantly.

🏛️

Veteran-anchored — 45% veterans vs 42% newcomers

■ 45% veterans ■ 12% 1-2yr ■ 42% new

Entry-cohort mix of 33 holders: 15 (45%) are 2+ year veterans, 4 entered 1–2 years ago, and 14 (42%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

📋

Smaller funds dominant — 6% AUM from top-100

6% from top-100 AUM funds

14 of 33 holders rank in the top 100 by AUM, but together hold only 6% of total institutional value. The stock is held primarily by smaller and mid-sized funds.

4.2

out of 10

Moderate Exit Risk

Exit risk score 4.2/10 — 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.
