Smart Money Signals — HBIO

Based on 60 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added HBIO 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.
🔻

Below peak — only 61% of 3.0Y high

61% of all-time peak
Only 60 funds hold HBIO today versus a peak of 99 funds at 2023 Q2 — just 61% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉

Outflows — 33% fewer funds vs a year ago

fund count last 6Q
30 fewer hedge funds hold HBIO compared to a year ago (-33% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡

Slight buying edge — 55% buying

33 buying27 selling
Last quarter: 33 funds bought or added vs 27 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.
📈

More new buyers each quarter (+6 vs last Q)

new funds entering per quarter
Funds opening a new HBIO position: 11 → 13 → 6 → 12. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

68% of holders stayed for 2+ years

■ 68% conviction (2yr+) ■ 13% medium ■ 18% new
41 out of 60 hedge funds have held HBIO 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.
💰

Price up while funds trimmed (+31% value, -14% shares)

Value
+30%
Shares
-14%
Last quarter: total value of institutional HBIO holdings rose +31% even though funds reduced share count by 14%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
📊

Peak discovery — momentum slowing

12 → 11 → 13 → 6 → 12 new funds/Q
New funds entering each quarter: 11 → 13 → 6 → 12. HBIO 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 — 76% of holders stayed 2+ years

■ 76% veterans ■ 6% 1-2yr ■ 18% new
Of 62 current holders: 47 (76%) 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.
✅

Strong quality — 20% AUM from major funds

20% from top-100 AUM funds
16 of 60 holders rank in the top 100 by AUM, accounting for 20% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
1.5
out of 10
Low Exit Risk
Exit risk score 1.5/10 — 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.
