Smart Money Signals — WST

Based on 752 hedge funds · latest filing: 2026 Q1 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their WST positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
🏔️

At the ownership peak (95% of max)

95% of all-time peak
752 hedge funds hold WST 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 — +7% more funds vs a year ago

fund count last 6Q
+52 new funds entered over the past year (+7% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠

More sellers than buyers — 47% buying

362 buying412 selling
Last quarter: 412 funds reduced or exited vs 362 that bought or added. When more than half of active funds are selling, it's a caution flag — especially if the stock price hasn't moved down yet.
⚠️

Fewer new buyers each quarter (-28 vs last Q)

new funds entering per quarter
Funds opening this position for the first time: 107 → 121 → 119 → 91. Each quarter fewer new institutions are entering. This usually means most funds that wanted in are already in — the stock is well-known but the pool of potential new buyers is shrinking.
🔒

66% of holders stayed for 2+ years

■ 66% conviction (2yr+) ■ 19% medium ■ 16% new
493 out of 752 hedge funds have held WST 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.
➡️

Steady discovery — ~91 new funds/quarter

99 → 107 → 121 → 119 → 91 new funds/Q
New funds entering each quarter: 107 → 121 → 119 → 91. Consistent flow of new institutional buyers without clear acceleration or slowdown.
🏛️

Veteran-anchored — 68% veterans vs 20% newcomers

■ 68% veterans ■ 12% 1-2yr ■ 20% new
Entry-cohort mix of 765 holders: 523 (68%) are 2+ year veterans, 88 entered 1–2 years ago, and 154 (20%) joined within the past year. A veteran-weighted cap table skews toward institutional memory over fresh momentum.
✅

Strong quality — 38% AUM from major funds

38% from top-100 AUM funds
64 of 749 holders rank in the top 100 by AUM, accounting for 38% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
3.4
out of 10
Low Exit Risk
Exit risk score 3.4/10 — 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.
