Smart Money Signals — PUBM

Based on 155 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 PUBM 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.
📊

High ownership — 82% of 3.0Y peak

82% of all-time peak
155 funds currently hold this stock — 82% of the 3.0-year high of 189 funds (reached 2024 Q2). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
〰️

Stable — ownership unchanged year-over-year

fund count last 6Q

🟡

Slight buying edge — 55% buying

92 buying76 selling
Last quarter: 92 funds bought or added vs 76 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 — ~32 new funds per quarter

new funds entering per quarter

Buying through price weakness — shares +7%, value -19%

Value
-18%
Shares
+6%
Last quarter: funds added +7% more shares while total portfolio value only changed -19%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.

Entry-cohort mix of 163 holders: 97 (60%) are 2+ year veterans, 23 entered 1–2 years ago, and 43 (26%) 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.
