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.
In 2026 Q1, 59 hedge funds were net buyers of MGNX (30 opened a new position, 29 added to an existing one), while 38 reduced or exited (29 trimmed, 9 sold completely) — a 61% buyer ratio, indicating clear institutional accumulation. 27% of total institutional value in MGNX is held by top-100 AUM funds, reflecting strong institutional quality. Net fund flow last quarter: +21 funds (more new holders than closures). Total institutional holders: 106.
Institutional ownership data sourced from SEC EDGAR Form 13F-HR filings.
Signal Freshness measures how much MGNX has moved relative to its sector benchmark (XLV) since the 2026 Q2 13F filing. A stock that has barely outrun its sector is still a relatively fresh entry point — the fund's thesis has not yet been priced in by the broader market.
MGNX outperformed XLV by -0.5% since June 30, 2026.
Interpretation: The stock is tracking its sector benchmark closely. The signal remains fresh and the entry point is still near the fund's implied reference. Learn more →

Buying streak — 1 quarter in a row: 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.
More buyers than sellers — 61% buying: 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.
Strong quality — 27% AUM from major funds: 28 of 106 holders rank in the top 100 by AUM, accounting for 27% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
60% of holders stayed for 2+ years: 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.
Since the quarter end (June 30, 2026), MGNX has gained +0.0% vs +0.5% for XLV. The stock is tracking its sector benchmark closely. The signal remains fresh and the entry point is still near the fund's implied reference.
