On the afternoon of April 24, 2026, at the annual general meeting of Construction Development and Investment Corporation (DIC Corp, ticker DIG, HoSE), a shareholder asked a blunt question: do repeated margin-call sales of the Chairman's and his family's shares hurt the company's image? Mr. Nguyen Hung Cuong, Chairman of the Board, replied that nobody wanted this to happen and that the whole episode was "entirely due to market volatility." Then he made a commitment: "we will gradually buy back and raise our ownership ratio at an appropriate time."Người Quan Sát
More than six months later, that statement has a completed transaction behind it.
Full volume, finished eight days early
According to the insider transaction report covered by Markettimes and Người Quan Sát on November 4, Mr. Cuong bought all 5 million DIG shares as registered.Markettimes The purchases ran from October 12 to November 2, 2026. His holding rose from nearly 28.8 million to nearly 33.8 million shares, lifting his stake from 3.41% to 4% of charter capital.Markettimes
The original registration ran through November 10, so he finished eight days early.Doanh nhân & Pháp luật That detail matters to anyone who tracks insider trades, because a purchase registration does not oblige the filer to buy the full amount. This time, executed volume matched registered volume exactly.
As for cost, over the 16 sessions from October 12 to November 2, DIG traded between VND 9,160 and VND 10,300, with an average closing price of VND 9,721. Multiplied by 5 million shares, that puts the outlay at roughly VND 46 billion to VND 52 billion. This is an estimate based on the market price range, not his actual purchase price.
The 4% stake next to the late-July margin sales
To judge whether 4% is large or small, it helps to set it against what happened a few months ago. From July 27 to July 30, 2026, Mr. Cuong had 5,201,800 DIG shares sold under margin calls, cutting his stake from 4.06% to 3.41%.Báo Đầu tư Chứng khoán He has now bought 5 million shares against roughly 5.2 million sold. Put differently, this purchase returns him to almost exactly where he stood just before the most recent round of sales, 0.06 percentage points short.
The late-July round was only part of the year. In the first half of 2026, Mr. Cuong's family had a total of more than 36.85 million DIG shares sold under margin calls, so the 5 million shares just bought are less than one-seventh of that figure.Báo Đầu tư Chứng khoán Người Quan Sát tallies it differently: since the start of the year, margin-sold DIG volume has reached about 44 million shares.Người Quan Sát The two counts cover different scopes and cannot be added together, but both show that the shares sold are many times the amount bought back.
Two of Mr. Cuong's relatives were also caught in the late-July sales. His mother had more than 1.2 million shares sold, leaving her at 1.08%. His sister, Ms. Nguyen Thi Thanh Huyen, Vice Chair of the Board at DIC Corp, had more than 1.65 million shares sold and holds about 0.79%.Markettimes
Why ownership falls even when no one sells
For newer investors, a "margin sale" works like this: a shareholder pledges shares as collateral for a loan, and the lending brokerage has the right to sell those shares if the collateral's value falls below the agreed level. The sell order is then placed by the brokerage, not the account holder. That is why the DIC Corp executives' stakes fell over several rounds even though they never placed sell orders themselves.
The price decline explains why the sales kept coming. From October 17, 2025 to November 2, 2026, DIG fell 61.4%, from VND 24,600 to VND 9,490, below its VND 10,000 par value.Báo Đầu tư Chứng khoán During the 16 sessions in which Mr. Cuong bought, the price topped par for only a few sessions around October 21 before returning to the VND 9,500 area. DIG closed at VND 9,500 on November 3. In the afternoon session on November 4, it was up about 4.4% while the VN-Index was up about 1.4%. One up session on the day the news broke is not enough to say whether the market reacted to Mr. Cuong's trades or simply followed the broader index.
The CEO's wife has also registered to buy
Around the same time, Ms. Vu Thi Thu Huong, wife of Mr. Nguyen Quang Tin, CEO of DIC Corp, registered to buy 1 million DIG shares between October 15 and November 13, 2026, through order matching and/or negotiated deals. If she buys the full amount, her holding would rise from 159,000 to nearly 1.2 million shares, or from 0.02% to 0.14% of charter capital.Markettimes
The scale is small next to Mr. Cuong's trade. Still, it shows the buyback is not confined to one person: the Chairman and the CEO's family, two different branches of the leadership, are moving in the same direction of raising ownership.
Business backdrop
On earnings, third-quarter net profit came in at VND 69.16 billion, down 64.2% year on year, but the nine-month total reached VND 202.69 billion, up 1.4%. Nine-month pre-tax profit was VND 241.85 billion, or 40.3% of the full-year plan of VND 600 billion.Báo Đầu tư Chứng khoán
What DIG holders can read from this trade
The April promise has become a real transaction, at the registered volume and ahead of schedule. After nearly a year of shares being sold out from under the family, the leadership's stake has risen a step, which is the clearest signal of its direction. Even so, the purchase only offsets Mr. Cuong's own late-July sales and remains far short of everything the family lost during the year. The trade shows management is adding to its stake, not cutting it. It says nothing about where the share price goes, which still depends on fourth-quarter results and the broader market.
Two signals are worth watching next: Ms. Huong's transaction report after November 13, which will show how much of her 1 million registered shares she bought, and any new transaction registrations DIC Corp files on HoSE, which will show whether Mr. Cuong's family keeps buying.
