Smart Money Signals — MRK

Based on 3780 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 consecutive quarters, more hedge funds added MRK 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
3,780 hedge funds hold MRK 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 — +12% more funds vs a year ago

fund count last 6Q
+410 new funds entered over the past year (+12% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 50% buying

1808 buying1787 selling
Last quarter: 1,808 funds bought or added vs 1,787 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.
⚠️

Fewer new buyers each quarter (-191 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 210 → 208 → 540 → 349. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒

72% of holders stayed for 2+ years

■ 72% conviction (2yr+) ■ 15% medium ■ 14% new
2,711 out of 3,780 hedge funds have held MRK 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.
🚀

Acceleration phase — new buyers rushing in

216 → 210 → 208 → 540 → 349 new funds/Q
New funds entering each quarter: 210 → 208 → 540 → 349. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.
🏛️

Veteran-anchored — 73% veterans vs 16% newcomers

■ 73% veterans ■ 11% 1-2yr ■ 16% new
Entry-cohort mix of 3,867 holders: 2,838 (73%) are 2+ year veterans, 426 entered 1–2 years ago, and 603 (16%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 50% AUM from top-100 funds

50% from top-100 AUM funds
70 of 3763 holders are among the 100 largest funds by AUM, controlling 50% of total institutional value in MRK. 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.
