Smart Money Signals — MGNX

Based on 106 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 1 quarter in a row

last 6Q

For 1 consecutive quarter, more hedge funds added MGNX 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.

🔻

Below peak — only 67% of 3.0Y high

67% of all-time peak

Only 106 funds hold MGNX today versus a peak of 159 funds at 2024 Q1 — just 67% of the maximum. Low institutional ownership can mean the stock is out of favor, but it also means there's a large pool of potential buyers if sentiment turns.

📉

Outflows — 15% fewer funds vs a year ago

fund count last 6Q

19 fewer hedge funds hold MGNX compared to a year ago (-15% decline). When institutions consistently reduce their exposure, it's worth exploring the underlying fundamental reasons driving them away.

🟢

More buyers than sellers — 61% buying

59 buying38 selling

Last quarter: 59 funds were net buyers (30 opened a brand new position + 29 added to an existing one). Only 38 were sellers (29 trimmed + 9 sold completely). A clear majority buying is a strong confirmation signal.

📈

More new buyers each quarter (+17 vs last Q)

new funds entering per quarter

Funds opening a new MGNX position: 26 → 18 → 13 → 30. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

■ 60% conviction (2yr+) ■ 16% medium ■ 24% new

64 out of 106 hedge funds have held MGNX 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.

💰

Value +59% but shares only +11% — price-driven

Value

+59%

+11%

Last quarter: the total dollar value of institutional holdings rose +59%, but actual share count only changed +11%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.

➡️

Steady discovery — ~30 new funds/quarter

19 → 26 → 18 → 13 → 30 new funds/Q

New funds entering each quarter: 26 → 18 → 13 → 30. Consistent flow of new institutional buyers without clear acceleration or slowdown.

🏛️

■ 70% veterans ■ 12% 1-2yr ■ 18% new

Of 111 current holders: 78 (70%) 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.

✅

Strong quality — 28% AUM from major funds

28% from top-100 AUM funds

28 of 106 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.

1.9

out of 10

Low Exit Risk

Exit risk score 1.9/10 — 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.
