Smart Money Signals — GOSS

Based on 190 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 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.
🏔️

At the ownership peak (96% of max)

96% of all-time peak
190 hedge funds hold GOSS 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 — +57% more funds vs a year ago

fund count last 6Q
+69 new funds entered over the past year (+57% 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 — 53% buying

124 buying110 selling
Last quarter: 124 funds bought or added vs 110 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 — ~48 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 32 → 54 → 51 → 48. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

42% of holders stayed for 2+ years

■ 42% conviction (2yr+) ■ 19% medium ■ 39% new
80 out of 190 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 -11%, value -97%

Value
-97%
Shares
-10%
Last quarter: funds added -11% more shares while total portfolio value only changed -97%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈

Growing discovery — still being found

27 → 32 → 54 → 51 → 48 new funds/Q
New funds entering each quarter: 32 → 54 → 51 → 48. A growing number of institutions are discovering GOSS each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 53% veterans vs 42% newcomers

■ 53% veterans ■ 5% 1-2yr ■ 42% new
Entry-cohort mix of 197 holders: 105 (53%) are 2+ year veterans, 10 entered 1–2 years ago, and 82 (42%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 33% AUM from major funds

33% from top-100 AUM funds
37 of 182 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.
4.6
out of 10
Moderate Exit Risk
Exit risk score 4.6/10 — 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.
