Smart Money Signals — MRCY

Based on 353 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 9 quarters in a row

last 6Q
For 9 consecutive quarters, more hedge funds added MRCY 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
353 hedge funds hold MRCY 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 — +41% more funds vs a year ago

fund count last 6Q
+103 new funds entered over the past year (+41% 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 — 53% buying

192 buying169 selling
Last quarter: 192 funds bought or added vs 169 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 — ~57 new funds per quarter

■ 65% veterans ■ 7% 1-2yr ■ 28% new
Of 363 current holders: 236 (65%) 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.
🏆

Moderate Exit Risk
Exit risk score 4.0/10 — 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.
