📈
Buying streak — 4 quarters in a row
For 4 consecutive quarters, more hedge funds added ACLS 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 — 93% of 3.0Y peak
93% of all-time peak
376 funds currently hold this stock — 93% of the 3.0-year high of 404 funds (reached 2023 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀
Fast accumulation — +26% more funds vs a year ago
fund count last 6Q
+78 new funds entered over the past year (+26% YoY). That's a rapid rush of institutional money. Fast accumulation often signals a major thesis — but it also means the stock could fall quickly if that thesis breaks.
🟠
More sellers than buyers — 47% buying
174 buying194 selling
Last quarter: 194 funds reduced or exited vs 174 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.
