The insider selling is routine and quantitatively trivial relative to market cap. No bearish signal. Monitor upcoming earnings or product announcements for any fundamental changes, but this cluster alone does not warrant action.
Price Chart
Executive Summary
Two Glaukos insiders (CFO and Chief Development Officer) sold a combined $1.6M in shares over a 7-day window. The CFO's sale followed option exercises at $38.68, a typical same-day exercise-and-sell pattern. At $8.8B market cap, the total sales represent only ~0.018% of market cap — well below the 0.1% threshold for materiality. This is routine insider selling with no bearish signal.
