GNTX GENTEX CORP
Price Chart
Executive Summary
Two Gentex directors sold ~5.9K shares each on the same day (May 15) at $22.98, totaling $273K. The transactions are small relative to the $5.0B market cap (~0.005%), and both were by non-C-suite directors, which carries minimal signaling weight per insider-sales literature.
Key Financial Metrics
Actionable Insight
This insider cluster is too small to warrant any trading action. Per academic literature, director-only sales carry near-zero predictive power for returns, and the cluster proportionality (<0.01% of market cap) is far below the 0.1% threshold for materiality. No read-through for current holders.
Key Facts
- Two directors sold 5,900 shares each at $22.98 on 2026-05-15
- Total sale value: $273K

Financial Impact
