KOS Forced Sale Fails as Chairman's Margin Call Hits Ninth Floor

Overview

Dai Viet Securities (DVSC) reported that its October 1 forced sale of KOS shares held by Kosy Chairman Nguyen Viet Cuong matched zero shares, as the stock closed at its ninth consecutive floor price. The failed execution, alongside similar unsuccessful margin calls on shares held by his wife and sister, underscores how frozen liquidity in KOS has left creditors unable to liquidate collateral on HOSE.

Key Facts

• DVSC placed a forced-sale order on Chairman Nguyen Viet Cuong’s KOS account on October 1, 2026; matched volume was 0 shares.
• KOS closed at VND 15,800 per share on October 1, down the full 6.8% daily limit, its ninth consecutive floor session.
• Only 2,500 KOS shares traded that day, indicating near-frozen liquidity.
• KOS has fallen more than 52% from VND 32,950 on September 15, 2026.
• Market capitalization fell to approximately VND 3,420 billion, down more than VND 3,700 billion from mid-September.
• On September 30, Capital Securities placed forced-sale orders on 450,000 KOS shares held by Vice Chairwoman Nguyen Thi Hang and 476,000 shares held by Deputy General Director Nguyen Thi Phuong Thao; both matched 0 shares.
• Cuong completed the sale of 4.3 million KOS shares between August 27 and September 24, leaving him with about 72.4 million shares, or 33.43% of Kosy, short of his registered 5 million-share plan.

What Happened

Dai Viet Securities (DVSC) published a report on the results of a forced sale of KOS shares held by Nguyen Viet Cuong, Chairman of the Board of Kosy. The brokerage executed the margin-call sale on October 1, 2026, but the number of shares matched during the session was zero. The report did not disclose how many shares were submitted for the forced sale.

The failed execution came as KOS faced heavy selling pressure with almost no offsetting demand. The same pattern had already appeared a day earlier: Capital Securities placed orders to force-sell 450,000 KOS shares belonging to Vice Chairwoman Nguyen Thi Hang, Cuong’s wife, and 476,000 shares belonging to Deputy General Director Nguyen Thi Phuong Thao, his sister. Neither order matched. Separately, Cuong reported completing the sale of 4.3 million KOS shares between August 27 and September 24, leaving him with roughly 72.4 million shares, or 33.43% of the company. He did not sell the full 5 million shares originally registered, citing unfavorable market conditions and failure to reach expected agreements.

Market Context

KOS trades on HOSE and closed at VND 15,800 on October 1, 2026, the ninth straight limit-down session. The stock has lost more than 52% since September 15, when it traded at VND 32,950, and market capitalization has fallen to about VND 3,420 billion from roughly VND 7,120 billion. The collapse reflects a broader pattern in Vietnamese real estate equities, where leveraged insider positions and thin order books can turn margin calls into self-reinforcing selloffs once a ticker hits consecutive floor prices.

Strategic Significance

For long-term investors, the key issue is not the forced sale itself but the mechanics it exposes: when insider collateral cannot be liquidated, the overhang of pledged shares remains unresolved and continues to pressure the order book. The chairman’s 33.43% stake is large enough to matter for control and governance, yet the failed margin calls suggest a portion of that holding is encumbered. Until the pledged-share situation is clarified and liquidity returns, any valuation case for Kosy rests on asset quality in its real estate portfolio rather than on near-term trading dynamics.

What to Watch

• Disclosure of the actual number of KOS shares pledged as collateral at DVSC and Capital Securities.
• Further forced-sale filings from DVSC or Capital Securities for Cuong and family members.
• Daily matched volume in KOS; a return above a few hundred thousand shares would signal liquidity is thawing.
• Any Kosy statement on debt restructuring, asset sales, or additional insider transactions.
• HOSE surveillance notices, including potential warnings or control-status changes tied to the price decline.
