Smart Money Signals — PRTK

Based on 64 hedge funds · latest filing: 2023 Q2 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q

For 1 consecutive quarter, more hedge funds added PRTK 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 60% of 3.0Y high

60% of all-time peak

Only 64 funds hold PRTK today versus a peak of 107 funds at 2021 Q2 — just 60% 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 — 12% fewer funds vs a year ago

fund count last 6Q

9 fewer hedge funds hold PRTK compared to a year ago (-12% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.

🟠

More sellers than buyers — 47% buying

32 buying36 selling

Last quarter: 36 funds reduced or exited vs 32 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.

📈

More new buyers each quarter (+13 vs last Q)

new funds entering per quarter

Funds opening a new PRTK position: 5 → 14 → 7 → 20. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

💎

Buying through price weakness — shares -8%, value -98%

Value

-98%

-8%

Last quarter: funds added -8% more shares while total portfolio value only changed -98%. 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

11 → 5 → 14 → 7 → 20 new funds/Q

New funds entering each quarter: 5 → 14 → 7 → 20. A growing number of institutions are discovering PRTK each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

1.1

out of 10

Low Exit Risk

Exit risk score 1.1/10 — 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.
