A foreign investor placing a buy order for Vietnamese shares and receiving a no-match notice because the room is full is a common experience on the two exchanges. The foreign ownership limit, the maximum aggregate stake foreign investors may hold in a public company, is not one single number for every ticker. It varies with the issuer business lines and with that company own charter, so the first step before any sizeable order is pinning down the ceiling of the specific stock.
The Legal Framework You Need
The legal framework for foreign ownership in public companies sits in the Law on Securities 54/2019/QH14 and Decree No. 155/2020/ND-CP. The general principle: for business lines outside the restricted market-access list, a public company may apply no limit or set its own maximum ratio in its charter; for sectors conditional for foreign investors, the ratio follows sector law and treaties, and where no specific rule exists, the default ceiling commonly applied is 49 percent of charter capital. Certain special sectors such as banking carry their own tighter ceiling under banking law.
Foreign ownership is calculated over total outstanding voting shares, and the regulator together with the depository tracks room in near real time: once aggregate foreign holdings touch the ceiling, new buy orders from foreign investors are blocked, leaving only sell orders or foreign-to-foreign transfers within technical limits. A public company must disclose its maximum foreign ownership ratio, and any change to that ratio requires a General Meeting of Shareholders resolution plus notification procedures with the State Securities Commission.
Applying the Rules to a Real Deal
Investors check remaining room from several official sources: the public company own disclosures, data of the stock exchange where the shares are listed, and depository records of the Vietnam Securities Depository and Clearing Corporation. In live trading, the securities company hosting the investor account displays available room at order entry, and that figure decides whether the order can enter the system. For large block trades, investors should check room as at the expected ownership transfer date, not merely the signing date, because room moves from session to session.
When room is full, lawful options remain, but none of them is a workaround purchase. First, buy from another foreign investor who is selling, because a foreign-to-foreign trade does not raise aggregate foreign ownership. Second, wait for the company to raise its room where the sector allows and shareholders approve. Third, consider non-voting depository receipts or related instruments issued by eligible issuers. What must be avoided absolutely is nominee holding through a domestic person, because nominee ownership breaches securities and investment law and can lead to forced divestment and sanctions.
Illustrative example: A Korean asset manager built a position in a listed pharmaceutical distributor and hit the room ceiling just below its target stake. Its compliance team mapped which foreign funds held the stock, negotiated an off-exchange foreign-to-foreign block purchase when one fund rebalanced, and documented the room check before and after settlement. The position reached the target six weeks later without a single order being rejected by the trading system.
Procedure and Documents to Prepare
First: identify the target public company main business lines and cross-check the conditional market-access list. Next: read the company charter and disclosures to learn the maximum foreign ownership ratio applying to that exact ticker. After that: check remaining room through the broker, the exchange and depository data as close as possible to the trade date. Then: plan purchases in tranches matching available room, preferring negotiated block trades for size. Finally: if room is full, choose a lawful alternative: foreign-to-foreign purchase, waiting for a room increase, or non-voting instruments.

Common Risks and How to Prevent Them
The first risk is applying the default 49 percent ceiling to every company, while each company has its own lower or higher cap by charter and sector. The second risk is room moving between signing and ownership transfer, so a negotiated block cannot settle as planned. The third and gravest risk is nominee holding through a domestic name, which can trigger sanctions, forced divestment and loss of shareholder rights. The safeguard is to verify room from official sources immediately before trading and to file the check evidence in the investor compliance record.
The foreign room moves with every trading session; a purchase decision is only safe when the foreign ownership ratio has been verified from official sources immediately before the order is placed. Keep the room-check evidence in the investor’s compliance file, ready to produce whenever the regulator asks.
Frequently Asked Questions
What is the foreign ownership limit (room) of a public company?
There is no single ratio for all public companies. The foreign ownership ceiling depends on the business lines and the charter of each company: unrestricted sectors may open up to 100 percent if shareholders so decide, conditional sectors without a specific rule commonly apply the default 49 percent of charter capital under the Decree No. 155/2020/ND-CP framework, and special sectors such as banking apply their own lower ceiling under sector law. To know the exact room of one ticker, investors must read that company own disclosures.
Where can I check the remaining room?
Three sources are reliable. First, the public company official disclosure of its maximum foreign ownership ratio and room status. Second, trading data of the stock exchange where the shares are listed or registered for trading. Third, the system of the securities company where you hold an account, which shows available room in real time at order entry. For a large negotiated trade, ask the broker to confirm the room in writing as at the intended execution date, so a mid-process room change does not break the deal.
If the room is full, is there any way to buy more shares?
There are lawful routes but no shortcuts. You may buy shares from another foreign investor who is selling, because aggregate foreign ownership does not increase. You may wait for, and support, a room increase where the company sector permits it and the General Meeting of Shareholders approves. Some investors use non-voting depository receipts issued by the public company to gain economic exposure without voting rights. By contrast, asking a domestic person to hold shares as nominee is a violation and should never be used.
