Smart Money Signals — APH

Based on 2116 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 11 quarters in a row

last 6Q
For 11 consecutive quarters, more hedge funds added APH 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
2,116 hedge funds hold APH 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 — +51% more funds vs a year ago

fund count last 6Q
+714 new funds entered over the past year (+51% 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 — 53% buying

1133 buying989 selling
Last quarter: 1,133 funds bought or added vs 989 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.
⚠️

Fewer new buyers each quarter (-66 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 332 → 286 → 335 → 269. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒

50% of holders stayed for 2+ years

■ 50% conviction (2yr+) ■ 24% medium ■ 26% new
1,061 out of 2,116 hedge funds have held APH 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.
➡️

Steady discovery — ~269 new funds/quarter

189 → 332 → 286 → 335 → 269 new funds/Q
New funds entering each quarter: 332 → 286 → 335 → 269. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 55% veterans vs 34% newcomers

■ 55% veterans ■ 11% 1-2yr ■ 34% new
Entry-cohort mix of 2,178 holders: 1,188 (55%) are 2+ year veterans, 247 entered 1–2 years ago, and 743 (34%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 53% AUM from top-100 funds

53% from top-100 AUM funds
70 of 2104 holders are among the 100 largest funds by AUM, controlling 53% of total institutional value in APH. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
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.
