This cluster is routine director-level selling at a trivial fraction of market cap. No C-suite participation and no unusual concentration suggest liquidity-driven diversification rather than informed selling. Monitor for any C-suite open-market sales in the next 30 days, which would carry more signal.
Price Chart
Executive Summary
Four FormFactor directors sold a total of $1.69M in open-market sales over a 7-day window (May 14–21, 2026), with three of the four trades clustered at ~$126/share near the stock's recent highs. The cluster is entirely director-level (no C-suite participation) and represents 0.017% of the $10B market cap — well below the 0.1% materiality threshold. The sales are likely routine portfolio diversification, not a bearish signal, especially given the absence of any C-suite selling or 10b5-1 pattern concerns.
Key Financial Metrics
Key Facts
- Four directors sold a total of 13,478 shares for $1.69M in open-market transactions over May 14–21, 2026.
- No C-suite executives (CEO, CFO, etc.) participated in the cluster — all sellers are directors.
- Total sales represent 0.017% of FormFactor's $10B market cap, far below the 0.1% materiality threshold.
- Three of four trades clustered at ~$126/share, near the stock's recent trading range.
- Recent insider activity (30d) shows 4 sells totaling $1.7M, consistent with this cluster's scale.
Financial Impact
Total insider sales of $1.69M, representing 0.017% of market cap — immaterial.
Risk Factors
- If additional C-suite selling emerges in the next 30 days, the signal would escalate.
- The stock is near recent highs — directors may be taking profits, but the dollar amount is too small to be informative.
