10% owner L. P. Cantor Fitzgerald sold 557,106 shares (557.1K) for $7,595,512.98 across 3 transactions at blended avg $13.63

L. P. Cantor Fitzgerald, a 10% owner, executed 3 separate sales totaling 557,106 shares for $7,595,512.98 ($7.6M) on July 15–16, 2026, reducing holdings by 8.6% from 6,451,535 shares to 5,894,429 shares. The insider's cross-ticker track record shows 20 prior open-market sells with an average 90-day return of +58.4% and a well-timed rate of 0.00%, indicating that prior sales were systematically poorly timed—stocks rose after the sales, suggesting the insider missed subsequent gains. Against this unfavorable pattern, this multi-day disposition by a significant shareholder merits monitoring for any divergence from historical outcomes, though the company's fundamentals show steady state: $124.8M quarterly revenue and +8.5% annual growth.

Significance 5

CFO Pamela L Bentley sold 80,000 shares (80.0K) for $929,408.00 in two transactions at GCMG on 2025-12-16/17.

Bentley executed two separate sales totaling 80,000 shares for $929,408.00 (blended average $11.62) on 2025-12-16 and 2025-12-17, reducing her holdings from 83,309 shares to 3,309 shares (a -96.0% reduction in her position). The stock currently trades at $11.65, only slightly above the transaction prices. Her same-ticker history at GCMG shows 3 prior sells (2023-12-15, 2023-12-18, 2023-12-19) where 2 of 3 were well-timed at the 90-day mark, suggesting a pattern of selling near local peaks at this ticker. However, the company's recent fundamentals remain solid: $135.0M quarterly revenue with annual growth of +15.5%, a P/E of 14.56, and net income of $10.5M. The scale of this sale (nearly complete liquidation of her position) represents a significant reduction in her direct equity stake in GCM Grosvenor.
