Executive Summary
Two Teradyne insiders, including the CEO, sold a combined $1.49M in open-market sales within a week. The CEO's $1.35M sale is the dominant transaction, but at ~0.46% of market cap, the cluster is modest in size and lacks a clear informational signal — no 10b5-1 plan indication is present, but the dollar value relative to market cap is not alarming.
Key Facts
- CEO Gregory Smith sold 4,000 shares sold open-market at $337.83 for $1.35M
- Director Marilyn Matz 800 shares sold open-market at $337.83 for $270K (across two days)
- Total cluster value $1.49M, approximately 0.46% of market cap
- No 10b5-1 plan indication on either sale
Financial Impact
Total insider sales of $1.49M, representing ~0.46% of market cap
Risk Factors
- CEO open-market sale without 10b5-1 plan could indicate negative outlook
- Cluster sales are generally weak predictors per academic literature
