📈
Buying streak — 3 quarters in a row
For 3 consecutive quarters, more hedge funds added STXS 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
114 hedge funds hold STXS 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 — +30% more funds vs a year ago
fund count last 6Q
+26 new funds entered over the past year (+30% 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 — 43% buying
46 buying61 selling
Last quarter: 61 funds reduced or exited vs 46 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.
📈
More new buyers each quarter (+8 vs last Q)
new funds entering per quarter
Funds opening a new STXS position: 7 → 19 → 16 → 24. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒
54% of holders stayed for 2+ years
■ 54% conviction (2yr+)
■ 18% medium
■ 28% new
62 out of 114 hedge funds have held STXS 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 +0%, value -20%
Last quarter: funds added +0% more shares while total portfolio value only changed -20%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
🚀
Acceleration phase — new buyers rushing in
11 → 7 → 19 → 16 → 24 new funds/Q
New funds entering each quarter: 7 → 19 → 16 → 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.
🏛️
Veteran-anchored — 59% veterans vs 30% newcomers
■ 59% veterans
■ 11% 1-2yr
■ 30% new
Entry-cohort mix of 116 holders: 68 (59%) are 2+ year veterans, 13 entered 1–2 years ago, and 35 (30%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

Moderate Exit Risk
Exit risk score 4.4/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
