Smart Money Signals — HTFL

Based on 165 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 HTFL 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

165 hedge funds hold HTFL 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 — +16400% more funds vs a year ago

fund count last 6Q

+164 new funds entered over the past year (+16400% 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 — 75% buying

123 buying42 selling

Last quarter: 123 funds were net buyers (73 opened a brand new position + 50 added to an existing one). Only 42 were sellers (25 trimmed + 17 sold completely). A clear majority buying is a strong confirmation signal.

📈

More new buyers each quarter (+24 vs last Q)

new funds entering per quarter

Funds opening a new HTFL position: 0 → 86 → 49 → 73. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

🔄

Mostly new holders — 98% entered in last year

■ 1% conviction (2yr+) ■ 2% medium ■ 98% 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.

💎

Buying through price weakness — shares +23%, value +5%

Value

+4%

+23%

Last quarter: funds added +23% more shares while total portfolio value only changed +5%. Institutions were buying while the price was falling — a high-conviction accumulation signal. They're deliberately loading up on the dip.

📈

Growing discovery — still being found

0 → 0 → 86 → 49 → 73 new funds/Q

New funds entering each quarter: 0 → 86 → 49 → 73. A growing number of institutions are discovering HTFL each quarter. The narrative is still spreading — leaving room for ongoing capital accumulation.

🌱

Early stage — 98% of holders entered in last year

■ 2% veterans ■ 0% 1-2yr ■ 98% new

Of 168 current holders: 164 (98%) entered in the past year, only 4 (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 — 51% AUM from top-100 funds

51% from top-100 AUM funds

39 of 165 holders are among the 100 largest funds by AUM, controlling 51% of total institutional value in HTFL. 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.
