Smart Money Signals — SNDX

Based on 243 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 SNDX 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
243 hedge funds hold SNDX 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 — +10% more funds vs a year ago

fund count last 6Q
+23 new funds entered over the past year (+10% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟡

Slight buying edge — 59% buying

143 buying100 selling
Last quarter: 143 funds bought or added vs 100 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 (+8 vs last Q)

new funds entering per quarter
Funds opening a new SNDX position: 30 → 40 → 34 → 42. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

53% of holders stayed for 2+ years

■ 53% conviction (2yr+) ■ 23% medium ■ 24% new
128 out of 243 hedge funds have held SNDX 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.

37 → 30 → 40 → 34 → 42 new funds/Q
New funds entering each quarter: 30 → 40 → 34 → 42. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 59% veterans vs 27% newcomers

■ 59% veterans ■ 14% 1-2yr ■ 27% new
Entry-cohort mix of 257 holders: 151 (59%) are 2+ year veterans, 36 entered 1–2 years ago, and 70 (27%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.

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.
