Smart Money Signals — GOSS

Based on 169 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds reduced or closed their GOSS 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 — 85% of 3.0Y peak

85% of all-time peak
169 funds currently hold this stock — 85% of the 3.0-year high of 198 funds (reached 2025 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀

Fast accumulation — +33% more funds vs a year ago

fund count last 6Q
+42 new funds entered over the past year (+33% 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 sellers than buyers — 49% buying

91 buying95 selling
Last quarter: 95 funds reduced or exited vs 91 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 (-20 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 54 → 51 → 48 → 28. 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.
🔒

40% of holders stayed for 2+ years

■ 40% conviction (2yr+) ■ 24% medium ■ 37% new
67 out of 169 hedge funds have held GOSS 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.
💎

Buying through price weakness — shares +115%, value -5%

Value
-5%
Shares
+115%
Last quarter: funds added +115% more shares while total portfolio value only changed -5%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊

Peak discovery — momentum slowing

32 → 54 → 51 → 48 → 28 new funds/Q
New funds entering each quarter: 54 → 51 → 48 → 28. GOSS 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 — 51% veterans vs 44% newcomers

■ 51% veterans ■ 6% 1-2yr ■ 44% new
Entry-cohort mix of 172 holders: 87 (51%) are 2+ year veterans, 10 entered 1–2 years ago, and 75 (44%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 30% AUM from major funds

30% from top-100 AUM funds
35 of 166 holders rank in the top 100 by AUM, accounting for 30% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
3.4
out of 10
Low Exit Risk
Exit risk score 3.4/10 — 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.
