Smart Money Signals — PRLB

Based on 259 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 4 quarters in a row

last 6Q
For 4 consecutive quarters, more hedge funds added PRLB 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
259 hedge funds hold PRLB 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 — +37% more funds vs a year ago

fund count last 6Q
+70 new funds entered over the past year (+37% 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 — 55% buying

128 buying105 selling
Last quarter: 128 funds bought or added vs 105 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 (+6 vs last Q)

new funds entering per quarter
Funds opening a new PRLB position: 32 → 33 → 47 → 53. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

65% of holders stayed for 2+ years

65% conviction (2yr+) 15% medium 20% new
169 out of 259 hedge funds have held PRLB 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.
🚀

Acceleration phase — new buyers rushing in

28 → 32 → 33 → 47 → 53 new funds/Q
New funds entering each quarter: 32 → 33 → 47 → 53. 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 — 74% veterans vs 21% newcomers

74% veterans 5% 1-2yr 21% new
Entry-cohort mix of 262 holders: 193 (74%) are 2+ year veterans, 13 entered 1–2 years ago, and 56 (21%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

Strong quality — 32% AUM from major funds

32% from top-100 AUM funds
49 of 258 holders rank in the top 100 by AUM, accounting for 32% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.0
out of 10
Moderate Exit Risk
Exit risk score 4.0/10 — 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.
