At the ownership peak (99% of max)
99% of all-time peak
272 hedge funds hold MTRN 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 — +20% more funds vs a year ago
fund count last 6Q

🟠
More sellers than buyers — 43% buying
112 buying150 selling
