DIG Chairman Buys 5 Million Shares After Margin Call: Insider Moves Across DIG, HDC, PNJ

Overview

DIC Corp (DIG, HOSE) Chairman Nguyen Hung Cuong has registered to buy 5 million DIG shares between 12 October and 10 November, lifting his ownership to 4% of charter capital after a series of margin calls cut his holding to 3.41%. The move follows similar insider registrations at Hodeco (HDC) and a forced sale of 2.94 million PNJ shares held by the daughter of PNJ Chairwoman Cao Thi Ngoc Dung, putting insider dealing at three Vietnamese listed companies in focus.

What Happened

According to company disclosures, DIC Corp Chairman Nguyen Hung Cuong registered to purchase 5 million DIG shares to raise his ownership to 4% of charter capital. The registration follows repeated margin calls: the family was force-sold nearly 37 million DIG shares in the first half of the year, and between 27 and 30 July a further 5,201,800 DIG shares were liquidated, reducing his stake to 3.41%. Vu Thi Thu Huong, wife of DIG General Director Nguyen Quang Tin, separately registered to buy 1 million DIG shares to reach 0.14% ownership.

At Hodeco, Chairman Doan Huu Thuan registered to buy 500,000 HDC shares to lift his stake to 9.21%, while his sons Doan Huu Ha An and Doan Huu Ha Vinh registered for 300,000 and 200,000 shares respectively. CEO Le Viet Lien registered for 1 million HDC shares to reach 3.93%. The registrations, totalling 2 million HDC shares, follow the margin call of 200,000 HDC shares held by the general director. Separately, PNJ Chairwoman Cao Thi Ngoc Dung’s daughter, Tran Phuong Ngoc Giao, was force-sold 2.94 million PNJ shares, cutting her holding to 11.7 million units, or 2.29% of charter capital; the filing did not disclose the reason or sale price.

Market Context

DIG closed at 9,400 on 11 October 2026, HDC at 10,100 and PNJ at 19,500. The DIG and HDC registrations come after a prolonged period of deleveraging in the Vietnamese real estate sector, where margin lending against concentrated family holdings has repeatedly triggered forced selling. PNJ, a retail jewellery name on HOSE, has seen prior insider selling, including 9 million shares sold by Cao Ngoc Duy, brother of the chairwoman, and stake reductions by T. Rowe Price Associates. The pattern points to margin pressure among large individual shareholders rather than company-level fundamentals.

Strategic Significance

For DIG, the chairman’s open-market purchase is a signal that the controlling family intends to rebuild its position after a damaging deleveraging cycle, though a 4% stake remains modest relative to the scale of prior forced sales. At HDC, coordinated buying by the chairman, CEO and family members suggests insiders view the recent share price as disconnected from asset value, a common thesis among Bà Rịa-Vũng Tàu land developers. The PNJ forced sale is different in character: it is a passive reduction by a family member rather than a change in the chairwoman’s own holding, but it adds to a visible trend of insider supply in a consumer-retail name that has historically traded at a premium valuation.

What to Watch

• Actual execution of the DIG and HDC registrations between 12 October and 13 November, and whether the full volumes are purchased.
• Further margin-call disclosures from the Cuong family or other large DIG shareholders.
• Any additional PNJ insider filings following the 2.94 million share forced sale.
• Q3 2026 earnings releases for DIG, HDC and PNJ, which will show whether operating performance supports the insider-buying thesis.
• Foreign-ownership and block-trade filings at PNJ, given T. Rowe Price’s prior stake reductions.
