Smart Money Signals — SIGA

Based on 178 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 SIGA 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 — 90% of 3.0Y peak

90% of all-time peak
178 funds currently hold this stock — 90% of the 3.0-year high of 197 funds (reached 2025 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📶

Steady growth — +11% more funds vs a year ago

fund count last 6Q
+18 new funds entered over the past year (+11% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠

More sellers than buyers — 47% buying

94 buying107 selling
Last quarter: 107 funds reduced or exited vs 94 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 — ~25 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 37 → 39 → 26 → 25. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

56% of holders stayed for 2+ years

■ 56% conviction (2yr+) ■ 24% medium ■ 20% new
99 out of 178 hedge funds have held SIGA 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.
📊

Peak discovery — momentum slowing

19 → 37 → 39 → 26 → 25 new funds/Q
New funds entering each quarter: 37 → 39 → 26 → 25. SIGA is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️

Veteran-anchored — 62% veterans vs 22% newcomers

■ 62% veterans ■ 16% 1-2yr ■ 22% new
Entry-cohort mix of 178 holders: 110 (62%) are 2+ year veterans, 28 entered 1–2 years ago, and 40 (22%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

45% from top-100 AUM funds
44 of 178 holders are among the 100 largest funds by AUM, controlling 45% of total institutional value in SIGA. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.3
out of 10

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.
