Smart Money Signals — CSGP

Based on 803 hedge funds · latest filing: 2025 Q4 · updated quarterly

📉

Selling streak — 1 quarter in a row

last 6Q
For 1 consecutive quarter, more hedge funds reduced or closed their CSGP 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 (96% of max)

96% of all-time peak
803 hedge funds hold CSGP 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 — +9% more funds vs a year ago

fund count last 6Q
+63 new funds entered over the past year (+9% YoY). Gradual, steady growth in institutional ownership is generally a healthy signal — not a speculative rush, but consistent conviction.
🟠

More sellers than buyers — 42% buying

373 buying510 selling
Last quarter: 510 funds reduced or exited vs 373 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.
📈

More new buyers each quarter (+8 vs last Q)

new funds entering per quarter
Funds opening a new CSGP position: 141 → 98 → 100 → 108. A growing influx of new institutional buyers means the asset is still gathering momentum — the consensus hasn't fully saturated yet.
🔒

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.
