Smart Money Signals — IMSR

Based on 87 hedge funds · latest filing: 2026 Q1 · updated quarterly

➡️

No change last quarter

last 6Q

The number of hedge funds holding this stock didn't change last quarter. Neither a buying nor selling signal on its own — watch the next quarter for direction.

🏔️

At the ownership peak (100% of max)

100% of all-time peak

87 hedge funds hold IMSR 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 — +8600% more funds vs a year ago

fund count last 6Q

+86 new funds entered over the past year (+8600% 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 — 50% buying

54 buying55 selling

Last quarter: 54 funds bought or added vs 55 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 (-56 vs last Q)

new funds entering per quarter

Funds opening this position for the first time: 0 → 0 → 86 → 30. 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.

🔄

Mostly new holders — 93% entered in last year

■ 1% conviction (2yr+) ■ 6% medium ■ 93% new

Only 1 funds (1%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.

➡️

Steady discovery — ~30 new funds/quarter

0 → 0 → 0 → 86 → 30 new funds/Q

New funds entering each quarter: 0 → 0 → 86 → 30. Consistent flow of new institutional buyers without clear acceleration or slowdown.

🌱

Early stage — 98% of holders entered in last year

■ 2% veterans ■ 0% 1-2yr ■ 98% new

Of 93 current holders: 91 (98%) entered in the past year, only 2 (2%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.

🏆

Elite ownership — 41% AUM from top-100 funds

41% from top-100 AUM funds

21 of 87 holders are among the 100 largest funds by AUM, controlling 41% of total institutional value in IMSR. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

7.3

out of 10

High Exit Risk

Exit risk score 7.3/10 — multiple crowding signals converge. Institutional ownership is at 100% of its all-time high — near peak crowding. Crowded trades can unwind fast — a single catalyst can trigger a cascade.

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.
