Smart Money Signals — RYTM

Based on 263 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 RYTM 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
263 hedge funds hold RYTM 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 — +36% more funds vs a year ago

fund count last 6Q
+70 new funds entered over the past year (+36% 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 — 54% buying

151 buying131 selling
Last quarter: 151 funds bought or added vs 131 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.
➡️

Steady new buyers — ~54 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 48 → 31 → 53 → 54. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

44% of holders stayed for 2+ years

■ 44% conviction (2yr+) ■ 28% medium ■ 28% new
117 out of 263 hedge funds have held RYTM 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.
💰

Price up while funds trimmed (+9% value, -85% shares)

Value
+8%
Shares
-84%
Last quarter: total value of institutional RYTM holdings rose +9% even though funds reduced share count by 85%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
📈

Growing discovery — still being found

48 → 48 → 31 → 53 → 54 new funds/Q
New funds entering each quarter: 48 → 31 → 53 → 54. A growing number of institutions are discovering RYTM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 51% of holders stayed 2+ years

■ 51% veterans ■ 15% 1-2yr ■ 34% new
Of 267 current holders: 137 (51%) 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.
✅

Strong quality — 34% AUM from major funds

34% from top-100 AUM funds
36 of 263 holders rank in the top 100 by AUM, accounting for 34% 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.
