Smart Money Signals — GKOS

Based on 335 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds added GKOS 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
335 hedge funds hold GKOS 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.
📶

Steady growth — +6% more funds vs a year ago

fund count last 6Q
+20 new funds entered over the past year (+6% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠

More sellers than buyers — 48% buying

161 buying172 selling
Last quarter: 172 funds reduced or exited vs 161 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.
⚠️

Fewer new buyers each quarter (-30 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 45 → 61 → 78 → 48. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒

58% of holders stayed for 2+ years

■ 58% conviction (2yr+) ■ 24% medium ■ 18% new
195 out of 335 hedge funds have held GKOS 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.
📈

Growing discovery — still being found

58 → 45 → 61 → 78 → 48 new funds/Q
New funds entering each quarter: 45 → 61 → 78 → 48. A growing number of institutions are discovering GKOS each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 66% of holders stayed 2+ years

■ 66% veterans ■ 13% 1-2yr ■ 21% new
Of 342 current holders: 225 (66%) 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 — 51% AUM from top-100 funds

51% from top-100 AUM funds
57 of 335 holders are among the 100 largest funds by AUM, controlling 51% of total institutional value in GKOS. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.7
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.
