The selling is dominated by Japan Post Holdings, a 10% owner with a known large stake — their sales likely reflect portfolio management rather than adverse company outlook. Koide's sales are exercise-and-sell, routine for option monetization. No insider buying to offset. Monitor next 10-Q for any change in Japan Post's ownership intent.
Price Chart
Executive Summary
AFLAC insider cluster shows net selling of ~$6.4M over the past week, dominated by Japan Post Holdings (10% owner) selling ~$4.7M in open-market transactions. President Koide Masatoshi also sold ~$1.6M after exercising options. The selling is material relative to AFLAC's $48B market cap (~0.013%), but the 10% owner's consistent selling pattern suggests portfolio rebalancing rather than negative company-specific news.
