Smart Money Signals — RPID

Based on 44 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q

For 3 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

44 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 — +57% more funds vs a year ago

fund count last 6Q

+16 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.

🟢

More buyers than sellers — 60% buying

29 buying19 selling

Last quarter: 29 funds were net buyers (12 opened a brand new position + 17 added to an existing one). Only 19 were sellers (9 trimmed + 10 sold completely). A clear majority buying is a strong confirmation signal.

➡️

Steady new buyers — ~12 new funds per quarter

new funds entering per quarter

Funds opening this position for the first time: 3 → 5 → 15 → 12. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.

📌

Mixed — 32% long-term, 43% new

■ 32% conviction (2yr+) ■ 25% medium ■ 43% new

Of the 44 current holders: 14 (32%) held >2 years, 11 held 1–2 years, and 19 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.

💎

Buying through price weakness — shares +8%, value -16%

Value

-15%

+8%

Last quarter: funds added +8% more shares while total portfolio value only changed -16%. 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

14 → 3 → 5 → 15 → 12 new funds/Q

New funds entering each quarter: 3 → 5 → 15 → 12. A growing number of institutions are discovering RPID each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

🌱

Early stage — 57% of holders entered in last year

■ 41% veterans ■ 2% 1-2yr ■ 57% new

Of 44 current holders: 25 (57%) entered in the past year, only 18 (41%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.

📋

Smaller funds dominant — 9% AUM from top-100

9% from top-100 AUM funds

16 of 44 holders rank in the top 100 by AUM, but together hold only 9% of total institutional value. The stock is held primarily by smaller and mid-sized funds.

5.1

out of 10

Moderate Exit Risk

Exit risk score 5.1/10 — 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.
