Smart Money Signals — RLYB

Based on 38 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added RLYB 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.
🔻

Below peak — only 62% of 3.0Y high

62% of all-time peak
Only 38 funds hold RLYB today versus a peak of 61 funds at 2024 Q2 — just 62% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.
📉

Outflows — 21% fewer funds vs a year ago

fund count last 6Q
10 fewer hedge funds hold RLYB compared to a year ago (-21% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.
🟡

Slight buying edge — 56% buying

20 buying16 selling
Last quarter: 20 funds bought or added vs 16 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 — ~11 new funds per quarter

new funds entering per quarter

Buying through price weakness — shares +152%, value +86%

Value
+85%
Shares
+151%
Last quarter: funds added +152% more shares while total portfolio value only changed +86%. 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

7 → 6 → 4 → 12 → 11 new funds/Q
New funds entering each quarter: 6 → 4 → 12 → 11. A growing number of institutions are discovering RLYB each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 55% veterans vs 29% newcomers

■ 55% veterans ■ 16% 1-2yr ■ 29% new
Entry-cohort mix of 38 holders: 21 (55%) are 2+ year veterans, 6 entered 1–2 years ago, and 11 (29%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

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.
