Doan Van Hieu Em, CEO of Dien May Xanh (DMX), bought an additional 732,000 DMX shares between September 10 and October 2, 2026, raising his ownership from 0.32% to 0.38%. He simultaneously sold 1 million MWG shares, reducing his stake in parent company The Gioi Di Dong to 0.08%. The trades were disclosed in an insider transaction filing published by DMX.

Key Facts

• Doan Van Hieu Em bought 732,000 DMX shares via order matching from September 10 to October 2, 2026.
• His DMX holding rose from 4.1 million shares (0.32%) to 4.83 million shares (0.38%).
• He previously bought 268,000 DMX shares on August 6, 2026, lifting his stake from 0.302% to 0.32%.

• The filing states the trades were portfolio restructuring to fund long-term investment in DMX.
• DMX board member Vo Ha Trung Tin registered to buy 100,000 DMX shares from September 18 to October 17, 2026, from zero holdings.

What Happened

According to the insider transaction report, Doan Van Hieu Em, who is also an executive board member at MWG, executed two opposing trades over roughly the same window. He accumulated DMX stock on-market while reducing his personal position in MWG, the parent company of Dien May Xanh. The filing attributes the shift to portfolio restructuring, with the stated aim of long-term alignment with DMX. This marks his second DMX purchase of 2026, following the August 6 transaction.

Separately, DMX fixed October 5, 2026 as the record date for shareholders eligible to attend an extraordinary general meeting on October 29, 2026, to be held both in person and online. The agenda covers a cash dividend paid from undistributed 2026 profit, a private placement of bonds with attached warrants, and other items delegated to the board chairman. The company did not disclose the dividend amount, the bond size, or the warrant terms in this announcement.

Market Context

DMX closed at 77,000 VND on October 5, 2026, while MWG closed at 74,400 VND the same day. The company metadata lists DMX on UPCOM, though the transaction report identifies the shares as trading on HoSE; the exchange designation should be verified against the latest listing notice. The trades sit within a Vietnamese retail sector that has drawn steady insider interest through 2026, with management teams at consumer-electronics and grocery chains adjusting personal holdings as earnings recover.

Strategic Significance

The signal for long-term investors is directional rather than size-based. A 0.38% stake is small in absolute terms, but the CEO’s decision to fund DMX purchases by selling MWG stock, and to describe the move as long-term alignment, points to a deliberate re-rating of the subsidiary relative to the parent. The pending bond-with-warrant issuance and cash dividend, if approved on October 29, would give DMX its own capital-markets identity rather than relying solely on MWG’s balance sheet. That separation is the core thesis to test.

What to Watch

• The October 29, 2026 EGM outcome, including the cash dividend per share and the bond-with-warrant terms.
• Whether Vo Ha Trung Tin completes his registered 100,000-share purchase by October 17, 2026.
• Any further DMX purchases or MWG sales by Doan Van Hieu Em in the next disclosure window.
• DMX’s Q3 2026 earnings release and the level of undistributed profit available for the dividend.
• Clarification of DMX’s listing venue, given the discrepancy between the UPCOM metadata and the HoSE reference in the filing.
