GH Guardant Health, Inc.
Price Chart
Executive Summary
Three Guardant Health directors sold a total of $1.81M in open-market sales over a 7-day window, with the largest sale ($1.23M) by Director Krognes at $132.51. The cluster is dominated by sales, but the total value is only ~0.01% of the $17.6B market cap, making it trivial in proportion. Non-cash derivative exercises by Joyce and Krognes have zero economic impact. The historical calibration shows a -2.41% average net alpha at T+20 for this segment, and the score-6 observed win rate is only 30%, suggesting limited predictive power for this cluster size.
Key Financial Metrics
Actionable Insight
This cluster is too small relative to market cap to warrant a directional trade. Monitor for any material corporate events (earnings, FDA decisions, M&A) that could explain director selling, but treat this as routine portfolio diversification. The historical calibration suggests limited edge on small clusters at this market cap.
