Japan Post Holdings Co., Ltd., a significant AFLAC insider, sold 14,895 shares on March 23, 2026 at $106.78 per share, a transaction worth about $1.59 million. While the share count is modest relative to AFLAC’s overall market value, the sale stands out because it is part of a steady series of disposals over multiple days rather than a one-off trade. Japan Post’s role matters because it is not a typical executive selling personal stock; it is a large strategic shareholder whose trades can reflect portfolio rebalancing, capital needs, or changes in ownership exposure. Over the last two weeks, Japan Post has reported near-daily sales, including additional sales of roughly $1.49 million (March 24), $1.52 million (March 25), and $809.93 thousand (March 26). That consistent cadence suggests an organized reduction plan rather than an isolated decision. Other insider activity has been limited by comparison. Director Lake Charles D II also sold about $536.37 thousand on March 25, but the dominant pattern in recent filings is Japan Post’s repeated selling. Retail investors often watch this kind of sustained selling because it can gradually increase share supply, even when each individual sale is relatively small.
