Overview
On August 7, 2026, the Ho Chi Minh City Stock Exchange (HOSE) updated its list of securities ineligible for margin trading, adding 57 stocks including Vietnam Airlines (HVN), Duc Giang Chemicals (DGC), and newly listed DMX.

- DGC (Duc Giang Chemicals) is on the list due to restricted trading status.

What Happened
HOSE announced an updated list of securities not eligible for margin trading, effective August 7, 2026. The list includes 57 stocks, with several high-profile names such as HVN, DGC, and DMX. According to the exchange’s regulations, investors cannot use credit limits (margin) provided by securities companies to purchase these stocks.
The reasons for inclusion vary by company. For example, DMX, which debuted on August 6, 2026, is ineligible because its listing period is under six months. HVN and DGC are on the list due to restricted trading status, while others like APG and APH are under warning status. Some stocks, such as DAH and HAP, are included because their audited 2025 net profits were negative.
Market Context
Vietnam Airlines (HVN), trading on HOSE, closed at VND 23,850 on August 7, 2026. The margin restriction could reduce buying interest, especially from retail investors who rely on leverage. DGC closed at VND 44,200, and DMX at VND 84,000. The move is part of HOSE’s regular review of margin eligibility, which often affects liquidity and short-term price movements. The broader market has been cautious amid regulatory tightening and global uncertainties.
Strategic Significance
For long-term investors, the margin ban is a short-term liquidity constraint rather than a fundamental change. HVN’s restricted status reflects ongoing financial challenges, but its strategic position as the national carrier remains. DGC’s inclusion may be temporary, depending on its compliance with listing rules. Investors should monitor these companies’ efforts to resolve the issues that led to their margin ineligibility, as removal from the list could signal improved financial health and attract renewed buying interest.
What to Watch
- Quarterly earnings reports for HVN, DGC, and other affected companies to assess financial recovery.
- Any announcements from HOSE regarding removal from the margin-ineligible list.
- Changes in stock prices and trading volumes for affected tickers in the coming weeks.
- Regulatory updates on the status of companies under warning or control, such as APG or DQC.
- For DMX, the six-month listing anniversary (around February 2027) when it may become margin-eligible.
