After Vietnam's Historic Stock Crash, Billionaire Heirs Spent VND 2 Trillion Buying the Dip

On March 9, the VN-Index plunged over 110 points in a single session, a drop of more than 6%. It was the largest single-day point decline in the history of Vietnam's stock market.

The panic hadn't even settled before the bosses and their children moved in. Within two days, at least six major purchase registrations surfaced, totaling over VND 2 trillion (roughly $80 million).

Two Heirs Led the Charge

The biggest move came from Trần Vũ Minh, son of Hòa Phát Group chairman Trần Đình Long. With HPG shares at a six-month low, he registered to buy 50 million shares, a deal worth about VND 1.33 trillion at the time. If completed, his stake in Hòa Phát would rise from 2.3% to nearly 3%.

On the other side, Nguyễn Phước Hùng Anh Victor, son of Vietjet chairman Nguyễn Thị Phương Thảo, registered to buy 2 million VJC shares. The stock had fallen nearly 30% from its late-2025 peak. Victor's purchase is estimated at VND 3,100 billion, with a trading window from March 13 to April 11, just ahead of the March 30 shareholders' meeting.

The Bosses Weren't Sitting Still Either

It wasn't just the next generation. The executives themselves were buying too.

Masan Group CEO Danny Le registered to buy 5 million MSN shares, estimated at about VND 3,650 billion.

Hoàng Anh Gia Lai (HAGL) chairman Đoàn Nguyên Đức had already registered to buy 5 million HAG shares in early March, worth around VND 760 billion.

Phát Đạt Real Estate chairman Nguyễn Văn Đạt registered to buy 3 million PDR shares for about VND 440 billion. Notably, he sold 88 million shares last September at around VND 24,000 each, cashing out over VND 2.1 trillion. Now with the stock down to VND 14,750, he's buying back in.

Doãn Chí Thiên, deputy general director of seafood giant Nam Việt, also registered to buy 1 million ANV shares for about VND 230 billion.

Why Now

The backdrop is clear.

In early March, tensions in the Middle East escalated sharply as military conflict between Iran and Israel intensified. Oil prices briefly approached $100 per barrel. Rising energy costs fueled inflation fears, the market worried about rate hikes, and money fled stocks fast.

On March 9, the VN-Index dropped from 1,768 to 1,653. Hundreds of stocks were locked at their daily limit-down. Retail investors who wanted out couldn't sell.

For corporate insiders, this was an opportunity. They know their companies' operations better than anyone. Share prices got dragged down by geopolitics, but the fundamentals didn't change. Buying at a discount is both an investment call and a signal of confidence to the market.

What Retail Investors Should Know

Insider buying is traditionally seen as a bullish signal, but there are a few caveats this time.

First, these are all "registered purchases," not completed transactions. Vietnamese securities law requires insiders to disclose before trading, but they don't always buy the full amount.

Second, the amounts are not that large relative to these families' wealth. Trần Vũ Minh's VND 1.33 trillion sounds like a lot, but his father Trần Đình Long has a net worth of over $2.5 billion.

Third, the Middle East situation remains unresolved and oil prices are still elevated. If the conflict escalates further, markets could take another leg down.

As of March 12, the VN-Index had bounced back to around 1,736, recovering about 5% from the low, but still short of where it was before the March 9 crash.

Still, when this many corporate leaders register to buy at the same time, how you read that signal is up to you.
