Based on 419 hedge funds · latest filing: 2026 Q2 · updated quarterly

📈

Buying streak — 3 quarters in a row

last 6Q

For 3 consecutive quarters, more hedge funds added ALKS 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

419 hedge funds hold ALKS 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.

📶

Steady growth — +20% more funds vs a year ago

fund count last 6Q

+70 new funds entered over the past year (+20% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.

🟡

Slight buying edge — 55% buying

234 buying192 selling

Last quarter: 234 funds bought or added vs 192 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 (+16 vs last Q)

new funds entering per quarter

Funds opening a new ALKS position: 45 → 60 → 76 → 92. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.

🔒

58% of holders stayed for 2+ years

■ 58% conviction (2yr+) ■ 17% medium ■ 24% new

245 out of 419 hedge funds have held ALKS for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.

💰

Value +54% but shares only +9% — price-driven

Value

+54%

+8%

Last quarter: the total dollar value of institutional holdings rose +54%, but actual share count only changed +9%. 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

44 → 45 → 60 → 76 → 92 new funds/Q

New funds entering each quarter: 45 → 60 → 76 → 92. 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.

🏛️

Veteran-anchored — 64% veterans vs 25% newcomers

■ 64% veterans ■ 12% 1-2yr ■ 25% new

Entry-cohort mix of 432 holders: 275 (64%) are 2+ year veterans, 51 entered 1–2 years ago, and 106 (25%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

🏆

Elite ownership — 52% AUM from top-100 funds

52% from top-100 AUM funds

61 of 418 holders are among the 100 largest funds by AUM, controlling 52% of total institutional value in ALKS. When the biggest players dominate the cap table, it signifies deep institutional support — since mega-funds deploy the most rigorous due diligence and capital.

3.9

out of 10

Low Exit Risk

Exit risk score 3.9/10 — 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.
