What Happened
According to filings disclosed by the companies, Mr. Đoàn Văn Hiểu Em, who serves as CEO of DMX and a member of the board at MWG, has registered to purchase 732,000 DMX shares. The transaction window runs from September 10 to October 9, 2026, and would lift his ownership to 0.38% of DMX’s charter capital. At the current market price, the purchase is estimated to cost around VND 57 billion.
In a parallel move, Mr. Hiểu Em registered to sell 1 million MWG shares between September 7 and October 6, 2026, reducing his MWG stake to 0.09%. The sale is estimated to generate approximately VND 73 billion. He stated the purpose is to rebalance his portfolio and shift toward a long-term investment in DMX. This follows his earlier sale of 2 million MWG shares in May 2026 for similar reasons.
Other insider transactions were also reported. At HAP, board member Trần Quang Tiến registered to buy 2 million shares from September 8 to October 6, which would increase his holding to 5.52% of the company. At SMC, CEO Nguyễn Quang Trung sold 4.9 million shares, reducing his stake to 1.36%, while Chairman Phạm Hoàng Anh purchased 5 million shares, raising his ownership to 8.14%. Additionally, TPC announced a plan to buy back 4 million treasury shares, representing nearly 24% of outstanding shares, with the intention to cancel them to boost future dividend payouts.
Market Context
DMX trades on the UPCOM exchange, closing at VND 78,000 on September 5, 2026. The insider buying comes as the VN-Index rose 20.96 points to 1,853.08 over the past week, while the HNX-Index slipped 2.24 points to 282.53. MWG, listed on HOSE, closed at VND 73,100 on the same date. The CEO’s shift from MWG to DMX may reflect a view that DMX offers better growth prospects, though his DMX stake remains small. Other affected tickers include HAP (HNX, close VND 7,320) and SMC (HOSE, close VND 10,050), where insider activity also signals changing expectations.
Strategic Significance
The insider trades highlight a rotation of management capital within Vietnam’s retail and materials sectors. Mr. Hiểu Em’s move to increase his DMX holding while trimming MWG suggests he sees greater upside in DMX’s business model, possibly tied to its expansion strategy. For long-term investors, such insider buying can be a signal of confidence, but the small stake size limits its significance. At SMC, the chairman’s large purchase contrasts with the CEO’s sale, indicating possible internal alignment or strategic shifts under new leadership. TPC’s treasury share buyback and cancellation is a capital-return move that could enhance shareholder value by reducing share count and increasing future dividends.
What to Watch
- Completion of Mr. Hiểu Em’s DMX purchase and MWG sale by the announced deadlines (October 9 and October 6, 2026, respectively).
- DMX’s upcoming quarterly earnings to assess whether the CEO’s confidence is justified.
- SMC’s operational performance under its new CEO and chairman, given the contrasting insider trades.
- TPC’s execution of the treasury share buyback and any subsequent dividend policy changes.
- Any further insider transactions at these companies that could confirm or reverse the current trends.
