From November 9, 2026, Hoa Binh Securities Joint Stock Company (ticker HBS) can no longer send trading orders into the system of the Ho Chi Minh City Stock Exchange (HoSE). Per CafeF, HoSE announced a temporary suspension of its trading connection with the firm from that date, to last until HBS fully resolves the problem.CafeF
For anyone holding shares at HBS, the first question is whether their assets are safe. The second is harder: where does the November 9 decision sit in the chain of restrictions the company has been through since late 2025, and what does a client gain if this one is lifted?
What HoSE announced on November 9
According to Doanh Nhan VN magazine, the measure followed a period of information-security monitoring. It rests on point a, clause 1, Article 19 of the regulation on IT systems connecting to HoSE and the Hanoi Stock Exchange (HNX), issued under Decision No. 39/QD-HDTV of May 28, 2026 by the Vietnam Exchange (VNX).Doanh Nhan VN The regulation lets an exchange disconnect a member proactively in an emergency, when a connected organization affects, or risks affecting, the exchange's operations and information security.
HoSE used only the word "incident" and the stated aim of "ensuring information security". This article therefore does not name the type of incident.
The conditions for reconnection are also written into the regulation. HBS must fix the problem, report the result and pass testing if the exchange asks for it.Nguoi Quan Sat The timing of reconnection therefore follows no fixed date. It depends on the company completing those steps.
What this touches for HBS clients
According to Vietnam Finance, the disconnection means HBS cannot route orders into the HoSE system through the suspended connections. The same outlet says the measure does not mean clients' securities accounts or assets at HBS are frozen.Vietnam Finance
In other words, HoSE-listed shares that clients hold in custody at HBS still belong to the clients. What is blocked is the channel for sending buy and sell orders on those shares to the exchange through this firm. And for HBS that channel had already narrowed nearly a year ago, because buying activity has been suspended since late 2025.
The restrictions in date order
To see where the new measure sits, it helps to put it next to each earlier step.
October 2025: special control. The State Securities Commission (SSC) issued Decision No. 816/QD-UBCK on October 23, 2025, placing HBS under special control.Doanh Nhan VN
November 28, 2025: buying activity suspended. VNX issued Decision No. 93/QD-SGDVN suspending HBS's securities buying activity on the listed and registered-for-trading markets at both HoSE and HNX, effective November 28, 2025. The stated reason was that the SSC had placed the company under special control.Vietnam Finance This is the only step in the chain whose document links directly to the one before it.
June 2026: plan to liquidate shares in client accounts. At the annual general meeting on June 12, 2026, HBS shareholders passed a resolution directing the board, together with the management team, to draw up a plan to sell off shares held in 481 client trading accounts.Vietnam Finance According to figures the company reported at the meeting, as of May 11, 2026 those accounts held over 10.22 million shares across 501 tickers, worth about VND 91.65 billion.CafeF The SSC later sent a document requiring HBS not to liquidate shares in client accounts on its own, and to comply with rules on asset management and protect investors' lawful rights.Vietnam Finance
August 2026: HBS shares kept on the restricted list. HNX decided to keep HBS shares under trading restrictions because the company filed its reviewed 2025 half-year financial statements more than 45 days late. Even if taken off the suspension list, HBS shares would trade only on Fridays each week until the restriction is lifted.Doanh Nhan VN
September 3, 2026: HBS shares suspended from trading. HNX placed HBS shares on the trading-suspension list from September 3, 2026, citing continued breaches of disclosure rules after the earlier restriction.CafeF Before the suspension, HBS had nearly 33 million shares listed on HNX. The stock sits at a reference price of VND 3,700, a market capitalization of about VND 122 billion, and has recorded no trades in the last five sessions through the morning of November 10.
November 9, 2026: HoSE cuts the trading connection. The stated reason is protecting system information security, different from the reasons for the earlier steps. The documents do not tie this decision to the special control or to the disclosure breaches, so it is treated here as a separate measure stacked on top of those still in force.
Each step targets a different object
The SSC targets the company, VNX targets buying activity, HNX targets HBS shares, and HoSE targets the technical connection. Because the objects differ, lifting one step does not automatically lift the others.
This is also where clients are most likely to be confused. A HoSE notice restoring the connection would matter, but it reopens only one path. Buying remains governed by VNX's decision, and HBS shares remain governed by HNX's.
The VNDirect precedent: a measure with a condition for ending
Disconnection has a precedent. On March 25, 2024, both HoSE and HNX cut trading connections with VNDirect Securities after a cyberattack on its systems. On April 1, 2024, once remediation was complete and the related requirements were met, VNDirect was reconnected.CafeF
The precedent speaks to the mechanism: a disconnection has a clear end condition, which is finishing the fix and passing testing. It says nothing about the cause of the HBS incident, and VNDirect's one week is no forecast for HBS. The context also differs: HBS faced several restrictions before the disconnection, so reconnecting does not return the company to full operation.
HBS's balance sheet
According to the Q3/2026 financial statements cited by Vietnam Finance, HBS recorded no revenue from brokerage or other securities business in the first nine months of 2026. Even so, the company posted pre-tax profit of VND 12.43 billion and after-tax profit of VND 9.94 billion over the nine months.Vietnam Finance For Q3 alone, after-tax profit was about VND 2.57 billion.CafeF
Financial revenue came to VND 15.62 billion over the nine months, mostly from deposit interest. Property rental income was VND 9.16 billion, including a share of rental revenue from the building at 246 Cong Quynh, Ho Chi Minh City. As of September 30, 2026, the company held VND 309.53 billion in bank deposits with 3-12 month terms, about 84.3% of total assets of VND 367.2 billion. Liabilities stood at about VND 10.78 billion, and the company had no margin loans outstanding at quarter-end.Vietnam Finance
A balance sheet like this shows HBS is under no debt pressure. The figures describe the company's size and sources of income. They say nothing further about the cause of the connection incident.
What will show the next step
For clients holding HoSE shares in custody at HBS, the document to wait for is HoSE's notice restoring the connection, issued after the company reports the fix and passes testing if the exchange requires it. That notice reopens only the order channel into HoSE. VNX's suspension of buying and HNX's suspension of HBS shares are separate decisions, each needing its own document to lift.
If HoSE reconnects while the other measures remain, HBS returns to exactly the position it held before November 9. If the connection is not restored, the newest restriction keeps stacking on the older ones, and every order for HoSE shares through the firm stays frozen.
