Smart Money Signals — LUNG

Based on 108 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds added LUNG 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.
📊

High ownership — 90% of 3.0Y peak

90% of all-time peak
108 funds currently hold this stock — 90% of the 3.0-year high of 120 funds (reached 2023 Q4). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
📉

Outflows — 8% fewer funds vs a year ago

fund count last 6Q
9 fewer hedge funds hold LUNG compared to a year ago (-8% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.

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.
