Smart Money Signals — MBX

Based on 154 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 7 quarters in a row

last 6Q

For 7 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.

🏔️

At the ownership peak (100% of max)

100% of all-time peak

154 hedge funds hold MBX 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 — +95% more funds vs a year ago

fund count last 6Q

+75 new funds entered over the past year (+95% 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 — 54% buying

83 buying72 selling

Last quarter: 83 funds bought or added vs 72 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 — ~38 new funds per quarter

new funds entering per quarter

Funds opening this position for the first time: 21 → 42 → 43 → 38. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.

🔄

Mostly new holders — 48% entered in last year

■ 5% conviction (2yr+) ■ 47% medium ■ 48% new

Only 8 funds (5%) 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.

📈

Growing discovery — still being found

28 → 21 → 42 → 43 → 38 new funds/Q

New funds entering each quarter: 21 → 42 → 43 → 38. A growing number of institutions are discovering MBX each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

🌱

Early stage — 63% of holders entered in last year

■ 6% veterans ■ 31% 1-2yr ■ 63% new

Of 158 current holders: 100 (63%) entered in the past year, only 9 (6%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.

✅

Strong quality — 28% AUM from major funds

28% from top-100 AUM funds

44 of 153 holders rank in the top 100 by AUM, accounting for 28% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.

5.3

out of 10

Moderate Exit Risk

Exit risk score 5.3/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
