Smart Money Signals — BDSX

Based on 40 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q

For 1 consecutive quarter, more hedge funds added BDSX 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 67% of 3.0Y high

67% of all-time peak

Only 40 funds hold BDSX today versus a peak of 60 funds at 2025 Q1 — just 67% 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

20 fewer hedge funds hold BDSX compared to a year ago (-33% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.

🟢

More buyers than sellers — 71% buying

30 buying12 selling

Last quarter: 30 funds were net buyers (23 opened a brand new position + 7 added to an existing one). Only 12 were sellers (2 trimmed + 10 sold completely). A clear majority buying is a strong confirmation signal.

📈

More new buyers each quarter (+16 vs last Q)

new funds entering per quarter

Funds opening a new BDSX position: 6 → 7 → 7 → 23. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

🔒

40% of holders stayed for 2+ years

■ 40% conviction (2yr+) ■ 28% medium ■ 32% new

16 out of 40 hedge funds have held BDSX 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.

💰

Value +404% but shares only +139% — price-driven

Value

+403%

+138%

Last quarter: the total dollar value of institutional holdings rose +404%, but actual share count only changed +139%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.

🚀

Acceleration phase — new buyers rushing in

11 → 6 → 7 → 7 → 23 new funds/Q

New funds entering each quarter: 6 → 7 → 7 → 23. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.

🏛️

Veteran-anchored — 56% veterans vs 32% newcomers

■ 56% veterans ■ 12% 1-2yr ■ 32% new

Entry-cohort mix of 41 holders: 23 (56%) are 2+ year veterans, 5 entered 1–2 years ago, and 13 (32%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

📋

Smaller funds dominant — 5% AUM from top-100

5% from top-100 AUM funds

9 of 40 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.

2.2

out of 10

Low Exit Risk

Exit risk score 2.2/10 — 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.
