Japan Post Holdings Co., Ltd., a major AFLAC shareholder, sold 35,804 AFLAC shares on May 19, 2026 at $118.55 per share, for a total of about $4.24 million. While the dollar amount is meaningful, the bigger news is the pace: Japan Post has been a steady seller in AFLAC over multiple sessions, with sizable sales reported almost daily from May 8 through May 19. This matters because Japan Post is not a typical executive insider buying or selling based on compensation or personal liquidity. As a large institutional holder with a long-standing relationship to AFLAC, its trades can reflect portfolio management decisions such as reducing a concentrated position, meeting capital needs, or rebalancing exposure. Retail investors often watch these moves because large holders can supply a meaningful amount of stock to the market over a short period. The selling continued after the May 19 transaction, with another reported sale of roughly $3.11 million on May 20. Over the same 30-day window, an individual insider, Thomas J. Kenny, also sold about $202,830 on May 15, but the dominant activity has been Japan Post’s repeated sales.
