Insider sales are immaterial relative to market cap and likely driven by diversification or tax planning. No bearish signal. Monitor next 10-Q for any fundamental deterioration, but this cluster alone does not warrant action.
Price Chart
Executive Summary
Four Coherent insiders, including the CTO and three directors, sold a total of $3.48M in stock over a 7-day window. The sales are small relative to the $51.8B market cap (~0.007%), making them routine and non-informative. The CTO's sales are the largest but still modest in absolute terms, and no open-market buying was detected to offset the selling.
