Smart Money Signals — WSBK

Based on 19 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 WSBK positions than added to them. Sustained institutional selling is a meaningful warning sign — these are professionals with deep research teams collectively deciding to exit.
📊

High ownership — 86% of 2.8Y peak

86% of all-time peak
19 funds currently hold this stock — 86% of the 2.8-year high of 22 funds (reached 2025 Q3). Ownership is elevated but not yet at maximum concentration. Room to grow, but watch if the trend reverses.
🚀

Fast accumulation — +1800% more funds vs a year ago

fund count last 6Q
+18 new funds entered over the past year (+1800% 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.
🔴

Heavy selling pressure — only 38% buying

5 buying8 selling
Last quarter: 8 funds sold vs only 5 buyers. This is widespread institutional distribution — not a few funds rebalancing, but a broad exit. High conviction bearish signal.
➡️

Steady new buyers — ~2 new funds per quarter

new funds entering per quarter
Funds opening this position for the first time: 18 → 4 → 3 → 2. A stable flow of new institutional buyers suggests ongoing interest without signs of either acceleration or slowdown.
🔄

Mostly new holders — 32% entered in last year

5% conviction (2yr+) 63% medium 32% new
Only 1 funds (5%) have held >2 years. The majority of current holders are relatively new to the position. New holders tend to sell faster when prices drop — a shallow conviction base that could amplify any sell-off.
💰

Price up while funds trimmed (+4% value, -11% shares)

Value
+4%
Shares
-10%
Last quarter: total value of institutional WSBK holdings rose +4% even though funds reduced share count by 11%. The stock price increased enough to offset the selling. Institutions are quietly trimming into price strength — watch for rotation.
⚠️

Saturation — most institutions already know this story

0 → 18 → 4 → 3 → 2 new funds/Q
New funds entering each quarter: 18 → 4 → 3 → 2. Far fewer institutions are entering now vs. a year ago. When the pool of potential new buyers shrinks this fast, future price support from institutional inflows weakens significantly.
🌱

Early stage — 95% of holders entered in last year

5% veterans 0% 1-2yr 95% new
Of 19 current holders: 18 (95%) entered in the past year, only 1 (5%) are 2+ year veterans. This is an early-phase institutional idea — still being discovered. High upside potential if the thesis plays out, but thin conviction base.
📋

Smaller funds dominant — 9% AUM from top-100

9% from top-100 AUM funds
6 of 19 holders rank in the top 100 by AUM, but together hold only 9% of total institutional value. The stock is held primarily by smaller and mid-sized funds.
4.7
out of 10
Moderate Exit Risk
Exit risk score 4.7/10 — some crowding factors present, but no critical concentration. Watch ownership trend over the next 1–2 quarters for direction.

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.
