Smart Money Signals — PBYI

Based on 162 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 11 quarters in a row

last 6Q
For 11 consecutive quarters, more hedge funds added PBYI 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
162 hedge funds hold PBYI 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 — +34% more funds vs a year ago

fund count last 6Q
+41 new funds entered over the past year (+34% 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 — 55% buying

87 buying70 selling
Last quarter: 87 funds bought or added vs 70 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 — ~26 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 25 → 33 → 27 → 26. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒

51% of holders stayed for 2+ years

■ 51% conviction (2yr+) ■ 25% medium ■ 23% new
83 out of 162 hedge funds have held PBYI 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.
💰

Value +29% but shares only +2% — price-driven

Value
+28%
Shares
+2%
Last quarter: the total dollar value of institutional holdings rose +29%, but actual share count only changed +2%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.
➡️

Steady discovery — ~26 new funds/quarter

21 → 25 → 33 → 27 → 26 new funds/Q
New funds entering each quarter: 25 → 33 → 27 → 26. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 57% veterans vs 31% newcomers

■ 57% veterans ■ 12% 1-2yr ■ 31% new
Entry-cohort mix of 164 holders: 94 (57%) are 2+ year veterans, 19 entered 1–2 years ago, and 51 (31%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 48% AUM from top-100 funds

48% from top-100 AUM funds
44 of 161 holders are among the 100 largest funds by AUM, controlling 48% of total institutional value in PBYI. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.9
out of 10
Low Exit Risk
Exit risk score 3.9/10 — 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.
