The insider selling cluster is too small relative to market cap to drive stock movement. Monitor MTG's upcoming quarterly earnings (next 10-Q) for any fundamental changes; meanwhile, this cluster does not warrant a directional trade.
Price Chart
Executive Summary
Three MTG insiders (CEO, President/COO, EVP/General Counsel) sold a total of $5.68M in open-market sales over Aug 3-7, 2026. At ~0.09% of market cap ($6.3B), the cluster is economically trivial and unlikely to carry a directional signal, consistent with routine portfolio diversification or tax planning.

- CEO sale of $4.18M may attract attention, but it is routine for a $6.3B company
