Smart Money Signals — MLM

Based on 1030 hedge funds · latest filing: 2025 Q4 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds added MLM 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
1,030 hedge funds hold MLM 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 — +13% more funds vs a year ago

fund count last 6Q
+119 new funds entered over the past year (+13% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 54% buying

487 buying412 selling
Last quarter: 487 funds bought or added vs 412 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.
📈

More new buyers each quarter (+30 vs last Q)

new funds entering per quarter
Funds opening a new MLM position: 110 → 132 → 121 → 151. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

62% of holders stayed for 2+ years

62% conviction (2yr+) 20% medium 18% new
640 out of 1,030 hedge funds have held MLM 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.
📈

Growing discovery — still being found

133 → 110 → 132 → 121 → 151 new funds/Q
New funds entering each quarter: 110 → 132 → 121 → 151. A growing number of institutions are discovering MLM each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Deep conviction — 63% of holders stayed 2+ years

63% veterans 13% 1-2yr 24% new
Of 1,046 current holders: 663 (63%) 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.
🏆

Elite ownership — 58% AUM from top-100 funds

58% from top-100 AUM funds
45 of 1030 holders are among the 100 largest funds by AUM, controlling 58% of total institutional value in MLM. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
3.6
out of 10
Low Exit Risk
Exit risk score 3.6/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
