Executive Summary

Two Guardant Health insiders sold a combined $1.38M in open-market sales over two days, led by the Chief Legal Officer ($1.25M). The total is ~0.008% of the $17.2B market cap — trivial in proportion. No C-suite buying or material insider conviction signal. The cluster is likely liquidity- or vesting-driven, not informational.
