Smart Money Signals — PSNL

Based on 141 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 4 quarters in a row

last 6Q
For 4 consecutive quarters, more hedge funds added PSNL 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
141 hedge funds hold PSNL 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 — +33% more funds vs a year ago

fund count last 6Q
+35 new funds entered over the past year (+33% 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.
🟢

More buyers than sellers — 60% buying

84 buying57 selling
Last quarter: 84 funds were net buyers (36 opened a brand new position + 48 added to an existing one). Only 57 were sellers (37 trimmed + 20 sold completely). A clear majority buying is a strong confirmation signal.
📈

More new buyers each quarter (+7 vs last Q)

new funds entering per quarter
Funds opening a new PSNL position: 33 → 21 → 29 → 36. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

42% of holders stayed for 2+ years

■ 42% conviction (2yr+) ■ 28% medium ■ 30% new
59 out of 141 hedge funds have held PSNL 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.

Shares

Last quarter: funds added +16% more shares while total portfolio value only changed -12%. 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

20 → 33 → 21 → 29 → 36 new funds/Q
New funds entering each quarter: 33 → 21 → 29 → 36. A growing number of institutions are discovering PSNL each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 57% of holders stayed 2+ years

■ 57% veterans ■ 10% 1-2yr ■ 33% new
Of 145 current holders: 82 (57%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.
✅

Strong quality — 20% AUM from major funds

20% from top-100 AUM funds
40 of 141 holders rank in the top 100 by AUM, accounting for 20% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
4.2
out of 10
Moderate Exit Risk
Exit risk score 4.2/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
