Smart Money Signals — IRON

Based on 216 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 4 quarters in a row

last 6Q
For 4 consecutive quarters, more hedge funds added IRON 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
216 hedge funds hold IRON 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 — +43% more funds vs a year ago

fund count last 6Q
+65 new funds entered over the past year (+43% 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 — 55% buying

118 buying95 selling
Last quarter: 118 funds bought or added vs 95 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 (-7 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 25 → 42 → 50 → 43. 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.
📌

Mixed — 36% long-term, 34% new

■ 36% conviction (2yr+) ■ 31% medium ■ 34% new
Of the 216 current holders: 77 (36%) held >2 years, 66 held 1–2 years, and 73 entered in the last year. A mixed base — the stock has long-term believers but also recent buyers who haven't been tested by a downturn yet.
📈

Growing discovery — still being found

25 → 25 → 42 → 50 → 43 new funds/Q
New funds entering each quarter: 25 → 42 → 50 → 43. A growing number of institutions are discovering IRON each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.
🏛️

Veteran-anchored — 44% veterans vs 36% newcomers

■ 44% veterans ■ 20% 1-2yr ■ 36% new
Entry-cohort mix of 225 holders: 100 (44%) are 2+ year veterans, 45 entered 1–2 years ago, and 80 (36%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
🏆

Elite ownership — 42% AUM from top-100 funds

42% from top-100 AUM funds
44 of 211 holders are among the 100 largest funds by AUM, controlling 42% of total institutional value in IRON. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
4.3
out of 10
Moderate Exit Risk
Exit risk score 4.3/10 — 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.
