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.
No strong consensus or elite conviction detected among institutional holders.

Buying streak — 6 quarters in a row: For 6 consecutive quarters, more hedge funds added MBX 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.
More buyers than sellers — 65% buying: Last quarter: 98 funds were net buyers (41 opened a brand new position + 57 added to an existing one). Only 53 were sellers (29 trimmed + 24 sold completely). A clear majority buying is a strong confirmation signal.
Smaller funds dominant — 17% AUM from top-100: 26 of 137 holders rank in the top 100 by AUM, but together hold only 17% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
Mostly new holders — 51% entered in last year: Only 6 funds (4%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
