📉

Selling streak — 1 quarter in a row

93% of all-time peak
175 funds currently hold this stock — 93% of the 3.0-year high of 188 funds (reached 2025 Q2). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
〰️

118 buying78 selling
Last quarter: 118 funds were net buyers (32 opened a brand new position + 86 added to an existing one). Only 78 were sellers (38 trimmed + 40 sold completely). A clear majority buying is a strong confirmation signal.
⚠️

Fewer new buyers each quarter (-14 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 39 → 20 → 46 → 32. 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.
🔒

■ 49% conviction (2yr+) ■ 29% medium ■ 22% new
85 out of 175 hedge funds have held ALT 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.
💎

Buying through price weakness — shares +20%, value +2%

Value
+1%
Shares
+19%
Last quarter: funds added +20% more shares while total portfolio value only changed +2%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.
📈

28 → 39 → 20 → 46 → 32 new funds/Q
New funds entering each quarter: 39 → 20 → 46 → 32. A growing number of institutions are discovering ALT each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

3.2
out of 10
Low Exit Risk
Exit risk score 3.2/10 — 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.
