Smart Money Signals — SI

Based on 56 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q
For 3 consecutive quarters, more hedge funds added SI 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
56 hedge funds hold SI 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 — +5500% more funds vs a year ago

fund count last 6Q
+55 new funds entered over the past year (+5500% 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.
🟢

More buyers than sellers — 70% buying

39 buying17 selling
Last quarter: 39 funds were net buyers (16 opened a brand new position + 23 added to an existing one). Only 17 were sellers (8 trimmed + 9 sold completely). A clear majority buying is a strong confirmation signal.
➡️

Steady new buyers — ~16 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 0 → 41 → 12 → 16. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄

Mostly new holders — 96% entered in last year

2% conviction (2yr+) 2% medium 96% new
Only 1 funds (2%) 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.
📊

Peak discovery — momentum slowing

0 → 0 → 41 → 12 → 16 new funds/Q
New funds entering each quarter: 0 → 41 → 12 → 16. SI is well-known in the hedge fund world, but fresh entries are gradually declining. The explosive phase of institutional discovery is likely behind us.
🌱

Early stage — 96% of holders entered in last year

4% veterans 0% 1-2yr 96% new
Of 56 current holders: 54 (96%) entered in the past year, only 2 (4%) 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 — 65% AUM from top-100 funds

65% from top-100 AUM funds
21 of 56 holders are among the 100 largest funds by AUM, controlling 65% of total institutional value in SI. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.
7.4
out of 10
High Exit Risk
Exit risk score 7.4/10 — 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.
