GH Guardant Health, Inc.
Price Chart
Executive Summary
Two Guardant Health insiders — the Chief Legal Officer and a Director — sold a combined $1.38M in open-market sales over a 7-day window. The CLO's $1.25M sale dominates the cluster. No insiders bought shares. The sales represent ~0.008% of the $16.8B market cap, well below the 0.1% materiality threshold, making this a routine liquidity-driven event.
Key Financial Metrics
Actionable Insight
Insider selling is immaterial in size and lacks a cluster of C-suite executives selling simultaneously. No bearish signal. Monitor the next 8-K or earnings release for any fundamental changes, but this cluster alone does not warrant a trading action.
Key Facts
- Chief Legal Officer John G. Saia sold 10,000 shares at $125.08 for $1.25M on 2026-05-27.
- Director Manuel Hidalgo Medina sold 1,000 shares at $130.06 for $130K on 2026-05-28.
- Total cluster value of $1.38M represents ~0.008% of GH's $16.8B market cap.
- No open-market purchases were made by any insider during the window.
- Director Joyce Meghan V. also sold 3,516 shares at $126.52 for $445K on 2026-06-03, but this was paired with derivative exercises (non-cash).
- The CLO's sale is the largest single trade and may be tied to a 10b5-1 plan or routine diversification.
Financial Impact
Total insider sales of $1.38M, or ~0.008% of market cap — trivial relative to company size.
Risk Factors
- Insider sales could accelerate if the stock continues to rally, but current volume is too small to indicate informed selling.
- No purchases to offset the sales — a lack of insider conviction, but not a negative signal at this scale.
