Smart Money Signals — RPID

Based on 41 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added RPID 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
41 hedge funds hold RPID 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 — +128% more funds vs a year ago

fund count last 6Q
+23 new funds entered over the past year (+128% 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 buyers than sellers — 77% buying

27 buying8 selling
Last quarter: 27 funds were net buyers (15 opened a brand new position + 12 added to an existing one). Only 8 were sellers (6 trimmed + 2 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+10 vs last Q)

new funds entering per quarter
Funds opening a new RPID position: 13 → 3 → 5 → 15. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

46% of holders stayed for 2+ years

46% conviction (2yr+) 24% medium 29% new
19 out of 41 hedge funds have held RPID 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.
📈

Growing discovery — still being found

2 → 13 → 3 → 5 → 15 new funds/Q
New funds entering each quarter: 13 → 3 → 5 → 15. A growing number of institutions are discovering RPID each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 56% of holders stayed 2+ years

56% veterans 2% 1-2yr 41% new
Of 41 current holders: 23 (56%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.
📋

Smaller funds dominant — 10% AUM from top-100

10% from top-100 AUM funds
12 of 41 holders rank in the top 100 by AUM, but together hold only 10% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
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.
