Smart Money Signals — GLSI

Based on 61 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 GLSI 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.
🏔️

At the ownership peak (100% of max)

100% of all-time peak
61 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 — +36% more funds vs a year ago

fund count last 6Q
+16 new funds entered over the past year (+36% 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.
🟢

More buyers than sellers — 65% buying

41 buying22 selling
Last quarter: 41 funds were net buyers (24 opened a brand new position + 17 added to an existing one). Only 22 were sellers (10 trimmed + 12 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 GLSI position: 8 → 5 → 8 → 24. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

41% of holders stayed for 2+ years

■ 41% conviction (2yr+) ■ 18% medium ■ 41% new
25 out of 61 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 +47% but shares only +28% — price-driven

Value
+46%
Shares
+28%
Last quarter: the total dollar value of institutional holdings rose +47%, but actual share count only changed +28%. 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

8 → 8 → 5 → 8 → 24 new funds/Q
New funds entering each quarter: 8 → 5 → 8 → 24. 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.
🏛️

Deep conviction — 51% of holders stayed 2+ years

■ 51% veterans ■ 8% 1-2yr ■ 41% new
Of 61 current holders: 31 (51%) 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 — 33% AUM from major funds

33% from top-100 AUM funds
21 of 61 holders rank in the top 100 by AUM, accounting for 33% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.3
out of 10
Moderate Exit Risk
Exit risk score 4.3/10 — 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.
