Based on 130 hedge funds · latest filing: 2019 Q3 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q

For 2 consecutive quarters, more hedge funds added ALDR 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

130 hedge funds hold ALDR 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 — +21% more funds vs a year ago

fund count last 6Q

+23 new funds entered over the past year (+21% 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 — 58% buying

81 buying58 selling

Last quarter: 81 funds bought or added vs 58 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.

📈

More new buyers each quarter (+31 vs last Q)

new funds entering per quarter

Funds opening a new ALDR position: 11 → 17 → 15 → 46. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

💰

Value +81% but shares only +13% — price-driven

Value

+80%

+13%

Last quarter: the total dollar value of institutional holdings rose +81%, but actual share count only changed +13%. The gap is explained by the stock's price rising — not new buying. Strong value growth with weak share growth means the rally is price momentum, not fresh institutional demand.

🚀

Acceleration phase — new buyers rushing in

13 → 11 → 17 → 15 → 46 new funds/Q

New funds entering each quarter: 11 → 17 → 15 → 46. The pace of institutional discovery is accelerating sharply. This is the 'hot idea' phase — the thesis is being passed from fund to fund. You are not late — the accumulation wave is still building.

3.3

out of 10

Low Exit Risk

Exit risk score 3.3/10 — low institutional crowding. Ownership is below peak levels, holder base is relatively sticky, and buying momentum is positive.

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.
