The dollar amounts are trivial relative to market cap, and the pattern of regular selling by multiple executives is consistent with routine portfolio diversification or tax planning. No actionable signal — ignore this cluster.
Price Chart
Executive Summary
Fastly CEO and CTO sold a combined $279K in open-market sales over a week, with the CTO's $227K sale representing the bulk. The total is ~0.008% of Fastly's $3.6B market cap — well below the 0.1% materiality threshold — making this a routine, non-informative cluster. Historical calibration shows score-6 reports in this segment have a 54% win rate and positive net alpha, but the dollar amounts here are too small to warrant an elevated score.
