Smart Money Signals — MLM

Based on 1066 hedge funds · latest filing: 2026 Q2 · updated quarterly

📉

Selling streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds reduced or closed their MLM positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🏔️

At the ownership peak (96% of max)

96% of all-time peak
1,066 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 — +8% more funds vs a year ago

fund count last 6Q
+79 new funds entered over the past year (+8% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠

More sellers than buyers — 48% buying

470 buying519 selling
Last quarter: 519 funds reduced or exited vs 470 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
📈

More new buyers each quarter (+7 vs last Q)

new funds entering per quarter
Funds opening a new MLM position: 135 → 161 → 109 → 116. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

65% of holders stayed for 2+ years

■ 65% conviction (2yr+) ■ 19% medium ■ 16% new
690 out of 1,066 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.
💎

Buying through price weakness — shares +93%, value +3%

Value
+2%
Shares
+93%
Last quarter: funds added +93% more shares while total portfolio value only changed +3%. 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

141 → 135 → 161 → 109 → 116 new funds/Q
New funds entering each quarter: 135 → 161 → 109 → 116. MLM is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🏛️

Veteran-anchored — 67% veterans vs 19% newcomers

■ 67% veterans ■ 13% 1-2yr ■ 19% new
Entry-cohort mix of 1,080 holders: 728 (67%) are 2+ year veterans, 143 entered 1–2 years ago, and 209 (19%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 53% AUM from top-100 funds

53% from top-100 AUM funds
67 of 1063 holders are among the 100 largest funds by AUM, controlling 53% 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.
3.4
out of 10
Low Exit Risk
Exit risk score 3.4/10 — 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.
