Smart Money Signals — QSI

Based on 154 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added QSI 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
154 hedge funds hold QSI 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 — +15% more funds vs a year ago

fund count last 6Q
+20 new funds entered over the past year (+15% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 57% buying

85 buying63 selling
Last quarter: 85 funds bought or added vs 63 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.
📈

More new buyers each quarter (+12 vs last Q)

new funds entering per quarter
Funds opening a new QSI position: 14 → 16 → 33 → 45. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
📌

Mixed — 39% long-term, 34% new

■ 39% conviction (2yr+) ■ 27% medium ■ 34% new
Of the 154 current holders: 60 (39%) held >2 years, 41 held 1–2 years, and 53 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
🚀

Acceleration phase — new buyers rushing in

37 → 14 → 16 → 33 → 45 new funds/Q
New funds entering each quarter: 14 → 16 → 33 → 45. 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 — 48% veterans vs 39% newcomers

■ 48% veterans ■ 13% 1-2yr ■ 39% new
Entry-cohort mix of 161 holders: 78 (48%) are 2+ year veterans, 21 entered 1–2 years ago, and 62 (39%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 36% AUM from major funds

36% from top-100 AUM funds
34 of 153 holders rank in the top 100 by AUM, accounting for 36% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.1
out of 10
Moderate Exit Risk
Exit risk score 4.1/10 — 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.
