📈
Buying streak — 4 quarters in a row
For 4 consecutive quarters, more hedge funds added MASS 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
114 hedge funds hold MASS 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.
🚀
Fast accumulation — +44% more funds vs a year ago
fund count last 6Q
+35 new funds entered over the past year (+44% 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.
🟡
Slight buying edge — 53% buying
60 buying53 selling
Last quarter: 60 funds bought or added vs 53 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
➡️
Steady new buyers — ~21 new funds per quarter
new funds entering per quarter
Funds opening this position for the first time: 22 → 26 → 19 → 21. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔒
45% of holders stayed for 2+ years
■ 45% conviction (2yr+)
■ 28% medium
■ 27% new
51 out of 114 hedge funds have held MASS for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
💎
Buying through price weakness — shares +7%, value -36%
Last quarter: funds added +7% more shares while total portfolio value only changed -36%. 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
17 → 22 → 26 → 19 → 21 new funds/Q
New funds entering each quarter: 22 → 26 → 19 → 21. MASS is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️
Deep conviction — 62% of holders stayed 2+ years
■ 62% veterans
■ 9% 1-2yr
■ 29% new
Of 116 current holders: 72 (62%) have held for over 2 years without selling. These are not momentum buyers — they have lived through drawdowns and stayed. A large veteran base acts as a stabilizing force during selloffs.

Moderate Exit Risk
Exit risk score 4.2/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.
