Based on 49 hedge funds · latest filing: 2025 Q4 · updated quarterly
➡️
No change last quarter
The number of hedge funds holding this stock didn't change last quarter. Neither a buying nor selling signal on its own — watch the next quarter for direction.
🏔️
At the ownership peak (100% of max)
100% of all-time peak
49 hedge funds hold GLSI right now — the highest count in 3.0 years. When ownership is this concentrated, any bad news can trigger a chain reaction: one big fund sells, others follow. This is a classic 'crowded trade' — high popularity doesn't equal safety.
🚀
Fast accumulation — +26% more funds vs a year ago
fund count last 6Q
+10 new funds entered over the past year (+26% 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 — 50% buying
24 buying24 selling
Last quarter: 24 funds bought or added vs 24 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 — ~8 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 8 → 8 → 5 → 8. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒
55% of holders stayed for 2+ years
■ 55% conviction (2yr+)
■ 27% medium
■ 18% new
27 out of 49 hedge funds have held GLSI 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 +131% but shares only +10% — price-driven
Last quarter: the total dollar value of institutional holdings rose +131%, but actual share count only changed +10%. 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.
📊
Peak discovery — momentum slowing
6 → 8 → 8 → 5 → 8 new funds/Q
New funds entering each quarter: 8 → 8 → 5 → 8. GLSI 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 — 69% of holders stayed 2+ years
■ 69% veterans
■ 12% 1-2yr
■ 18% new
Of 49 current holders: 34 (69%) 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.
🏆
Elite ownership — 56% AUM from top-100 funds
56% from top-100 AUM funds
20 of 49 holders are among the 100 largest funds by AUM, controlling 56% of total institutional value in GLSI. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
Exit risk score 3.7/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.
