Smart Money Signals — ALKS

Based on 383 hedge funds · latest filing: 2026 Q1 · updated quarterly

📈

Buying streak — 2 quarters in a row

last 6Q
For 2 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
383 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 — +5% more funds vs a year ago

fund count last 6Q
+19 new funds entered over the past year (+5% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 50% buying

199 buying200 selling
Last quarter: 199 funds bought or added vs 200 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: 43 → 44 → 60 → 76. 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+) ■ 19% medium ■ 22% new
224 out of 383 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.
💰

Price up while funds trimmed (+22% value, -4% shares)

Value
+21%
Shares
-4%
Last quarter: total value of institutional ALKS holdings rose +22% even though funds reduced share count by 4%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
🚀

Acceleration phase — new buyers rushing in

66 → 43 → 44 → 60 → 76 new funds/Q
New funds entering each quarter: 43 → 44 → 60 → 76. 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 23% newcomers

■ 64% veterans ■ 13% 1-2yr ■ 23% new
Entry-cohort mix of 396 holders: 254 (64%) are 2+ year veterans, 52 entered 1–2 years ago, and 90 (23%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

34% from top-100 AUM funds
56 of 381 holders rank in the top 100 by AUM, accounting for 34% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.

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.
