Smart Money Signals — RCUS

Based on 207 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 RCUS 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
207 hedge funds hold RCUS 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 — +14% more funds vs a year ago

fund count last 6Q
+25 new funds entered over the past year (+14% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 57% buying

121 buying93 selling
Last quarter: 121 funds bought or added vs 93 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.
⚠️

Fewer new buyers each quarter (-11 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 25 → 31 → 49 → 38. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒

57% of holders stayed for 2+ years

■ 57% conviction (2yr+) ■ 20% medium ■ 23% new
117 out of 207 hedge funds have held RCUS 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

32 → 25 → 31 → 49 → 38 new funds/Q
New funds entering each quarter: 25 → 31 → 49 → 38. 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 — 67% veterans vs 25% newcomers

■ 67% veterans ■ 8% 1-2yr ■ 25% new
Entry-cohort mix of 219 holders: 146 (67%) are 2+ year veterans, 18 entered 1–2 years ago, and 55 (25%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 24% AUM from major funds

24% from top-100 AUM funds
43 of 206 holders rank in the top 100 by AUM, accounting for 24% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
3.8
out of 10
Low Exit Risk
Exit risk score 3.8/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
