Smart Money Signals — AMTM

Based on 464 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their AMTM 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 (95% of max)

95% of all-time peak
464 hedge funds hold AMTM 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 AMTM is almost the same as a year ago (+6 funds, +1% change). No significant rush to buy or sell — institutional backing is holding steady.
🟠

More sellers than buyers — 46% buying

213 buying251 selling
Last quarter: 251 funds reduced or exited vs 213 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.
⚠️

Fewer new buyers each quarter (-13 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 74 → 96 → 75 → 62. 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.
🔄

Mostly new holders — 25% entered in last year

■ 4% conviction (2yr+) ■ 71% medium ■ 25% new
Only 19 funds (4%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
💎

Buying through price weakness — shares +4%, value -15%

Value
-15%
Shares
+3%
Last quarter: funds added +4% more shares while total portfolio value only changed -15%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📊

Peak discovery — momentum slowing

113 → 74 → 96 → 75 → 62 new funds/Q
New funds entering each quarter: 74 → 96 → 75 → 62. AMTM is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
📊

Mixed cohorts — 2% veterans, 29% new entrants

■ 2% veterans ■ 69% 1-2yr ■ 29% new
Of 482 current holders: 10 (2%) held 2+ years, 333 held 1–2 years, 139 (29%) entered in the past year. Balanced distribution — some institutional memory, some recent momentum buyers.
🏆

Elite ownership — 51% AUM from top-100 funds

51% from top-100 AUM funds
53 of 460 holders are among the 100 largest funds by AUM, controlling 51% of total institutional value in AMTM. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.6
out of 10
Low Exit Risk
Exit risk score 3.6/10 — 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.
