The sale of 95,000 shares was in line with his prior registration. Following the transaction, his ownership fell to 4,989,438 shares, or 0.144% of SeABank’s charter capital.
In addition to Khoan’s transaction, several other SeABank executives and relatives of board members have registered to sell SSB shares.

Notably, Le Tuan Anh, son of Vice Chairwoman Nguyen Thi Nga, registered to sell 8 million shares, and Nguyen Tuong Huy, son of Vice Chairwoman Khuc Thi Quynh Lam, registered to sell nearly his entire holding of 214,100 shares.

Market Context
SSB is listed on the Ho Chi Minh Stock Exchange (HOSE). The insider sales come after a sharp rally in SSB shares in early September 2026, with the stock hitting a record high on September 18 before pulling back. On September 24, SSB closed at 20,000 VND, down 2.4% for the session but still up 38% since the start of the year. SeABank’s market capitalization stands at approximately 69,380 billion VND. The banking sector has been a key driver of the Vietnamese market’s performance in 2026, and SSB’s strong year-to-date gain reflects broader optimism, but the cluster of insider sales could test short-term sentiment.
Strategic Significance
For long-term investors, the wave of insider sales at SeABank warrants attention as a potential signal of valuation concerns or portfolio rebalancing by executives. While individual sales for personal financial reasons are common, the concentration of registrations from multiple senior leaders and family members of board members may raise questions about their confidence in the stock’s near-term upside. However, the bank’s fundamentals remain solid, with total assets growing 8% in the first half of 2026 to over 427,100 billion VND and credit growth of nearly 8%. The accidental buy by Deputy CEO Khoan is a minor technicality but highlights the importance of robust internal controls. Investors should monitor whether these sales are executed as planned and if further insider activity emerges.
What to Watch
- Execution of the registered share sales by Deputy CEOs Nguyen Tuan Anh, Dang Thu Trang, and Bui Quoc Hieu between September and October 2026.
- Completion of Le Tuan Anh’s 8 million share sale and its impact on his ownership percentage.
