Smart Money Signals — AMT

Based on 1754 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds reduced or closed their AMT positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🏔️

At the ownership peak (96% of max)

96% of all-time peak
1,754 hedge funds hold AMT 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.
〰️

Stable — ownership unchanged year-over-year

fund count last 6Q
The number of hedge funds holding AMT is almost the same as a year ago (-59 funds, -3% change). No significant rush to buy or sell — institutional backing is holding steady.
🟡

Slight buying edge — 52% buying

900 buying844 selling
Last quarter: 900 funds bought or added vs 844 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 (-39 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 161 → 139 → 211 → 172. 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.
🔒

72% of holders stayed for 2+ years

■ 72% conviction (2yr+) ■ 16% medium ■ 12% new
1,265 out of 1,754 hedge funds have held AMT 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.
📈

Growing discovery — still being found

214 → 161 → 139 → 211 → 172 new funds/Q
New funds entering each quarter: 161 → 139 → 211 → 172. A growing number of institutions are discovering AMT each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 74% veterans vs 16% newcomers

■ 74% veterans ■ 10% 1-2yr ■ 16% new
Entry-cohort mix of 1,813 holders: 1,346 (74%) are 2+ year veterans, 185 entered 1–2 years ago, and 282 (16%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 60% AUM from top-100 funds

60% from top-100 AUM funds
72 of 1749 holders are among the 100 largest funds by AUM, controlling 60% of total institutional value in AMT. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.1
out of 10
Low Exit Risk
Exit risk score 3.1/10 — 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.
