📉

92% of all-time peak
158 funds currently hold this stock — 92% of the 3.0-year high of 172 funds (reached 2024 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
〰️

Value
-33%
Shares
-3%
Last quarter: funds added -3% more shares while total portfolio value only changed -33%. 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

26 → 21 → 42 → 26 → 25 new funds/Q
New funds entering each quarter: 21 → 42 → 26 → 25. HDSN is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.

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.
