Smart Money Signals — ALT

Based on 209 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added ALT 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
209 hedge funds hold ALT 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.
📶

Steady growth — +11% more funds vs a year ago

fund count last 6Q
+21 new funds entered over the past year (+11% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟢

More buyers than sellers — 71% buying

149 buying60 selling
Last quarter: 149 funds were net buyers (59 opened a brand new position + 90 added to an existing one). Only 60 were sellers (35 trimmed + 25 sold completely). A clear majority buying is a strong confirmation signal.

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.
