While the absolute dollar amount is routine for a $1.3B market cap, the unanimous selling by the top three insiders (CEO, CSBO, President/CMO) without a single open-market buy creates a bearish optical signal. The CROSS-FILING ACTUARIAL AMPLIFIER applies (cluster-insider-trades + multiple context categories), suggesting these trades may be signaling ahead of earnings or a corporate event. Monitor for any 8-K (2.02 earnings miss or 2.05 restructuring) in the next 14 days — a negative event would validate the cluster's timing and could trigger a 5-7% downside move given the stock's poor T+20 historical calibration.
Price Chart
Executive Summary
Three Maze Therapeutics insiders sold a combined $1.20M in open-market stock over a 6-day window, including the CEO, President/R&D/CMO, and CSBO. None of these sales are 10b5-1 plan trades — all are fully discretionary. The CEO sold the largest tranche ($666K) right before a 2% stock dip, and the President sold after an additional 1.8% decline. At a $1.3B market cap, the cluster represents 0.09% of shares outstanding, falling below the 0.1% materiality threshold, but the complete lack of any insider buying and the uniform selling by the three most senior R&D/C-suite executives warrants heightened scrutiny ahead of the next catalyst event.

Financial Impact
Insider selling of $1.2M, or ~0.09% of $1.3B market cap — below the 0.1% materiality threshold
Risk Factors
- Uniform insider selling without any buys increases the risk of adverse news flow near-term
- Historical MAZE calls underperformed SPY by -19.6% at T+20, indicating persistent selling pressure or disappointing catalysts
- Cross-filing calibrations flag amplifiers but the score-4/5 neutral calls in the past have still produced -9% T+5 moves
- If the CEO's sale was pre-planned (10b5-1 is not disclosed in this data), that would reduce the bearish signal
