Kosy (KOS, HOSE) shares rose 6.9% to the daily ceiling of VND 4,340 per share in the morning of November 2, their second consecutive ceiling-price session. The move followed 29 straight floor-price sessions from September 21 to October 29, during which the price fell about 90%. Morning trading volume reached nearly 6.9 million shares, and buy orders at the ceiling still exceeded 4 million shares. Entities linked to Chairman Nguyễn Việt Cường continued to face forced selling, while his sister-in-law Hoàng Thị Yến has registered to buy 8 million shares from October 15 to November 13. Kosy said brokers cutting margin lending and forced selling had increased supply pressure, while its operations remained normal. For the first six months of 2026, net revenue was nearly VND 722 billion, up 9%, and after-tax profit was nearly VND 15.4 billion, up about 120%, equal to roughly 13% of its full-year profit plan.

- One Stock Snaps 29-Session Floor-Price Losing Streak; One-Third of Companies Change Hands
Shares of Kosy Corp (KOS) hit the daily limit up at 4,060 VND per share in the morning session on Oct 30, ending a streak of 29 consecutive floor-price sessions that began on Sept 21, with over 74 million shares matched. During the slide, the stock fell from above 30,000 VND per share on Sept 18 to 3,800 VND at the close on Oct 29, losing more than 87% of its value and shrinking market capitalization by about 5,700 billion VND. Selling pressure came from margin-call forced sales by several major shareholders and related parties, including Chairman Nguyễn Việt Cường, but only about 2.44 million shares were sold this way because many sales failed for lack of matching buyers. Kosy attributed the drop to investor sentiment, brokerages reducing margin lending ratios and forced selling, and said its core real estate and renewable energy businesses continue as planned. In H1 2026, revenue reached nearly 723 billion VND (up 9% year on year) and after-tax profit was about 15 billion VND, while borrowings of nearly 2,000 billion VND made up over 73% of total liabilities.
- Rare Plunge for KOS: Hit Floor Price for 29 Consecutive Sessions, Market Cap Evaporates Nearly VND 6,000 Billion
KOS shares of Kosy Joint Stock Company closed at the floor price of VND 3,800 per share on October 29, down nearly 7%, marking the 29th consecutive session at the floor. More than 63 million shares were still waiting to be sold at the floor price, while only about 1.4 million shares changed hands. Compared with the close above VND 30,000 per share on September 18, the price has fallen more than 87%, shrinking market capitalization from over VND 6,500 billion to about VND 823 billion. Forced-sale notices kept appearing for shares held by Chairman Nguyễn Việt Cường, Mr. Nguyễn Trung Kiên, Kosy Real Estate and Leo Regulus, but most sell orders failed to match. Kosy said its real estate and renewable energy operations remain on schedule, and for the first half of 2026 it reported revenue of nearly VND 723 billion, up 9%, and profit after tax of about VND 15 billion.
- Company linked to Kosy Group chairman continues to have KOS shares force-sold
Kosy Real Estate Investment Co., Ltd, a company linked to Kosy Group Chairman Nguyễn Việt Cường, had 754,900 KOS shares force-sold by a securities firm between 9 and 15 October 2026, reducing its stake from 4.605% to 4.26%. It had also been forced to sell 8,000 shares on 29/9/2026 and from 1/10/2026 to 5/10/2026. Leo Regulus Investment JSC, another company linked to Cường and Deputy Chairwoman Nguyễn Thị Hằng, had 4,732 shares sold, cutting its stake to 10.251%. Meanwhile, Cường's sister-in-law, Hoàng Thị Yến, registered to buy 8 million KOS shares from 15/10/2026 to 13/11/2026, which would raise her stake to 3.71%. Kosy said KOS hit the floor price for 5 consecutive sessions from 5/10 to 9/10/2026 due to market momentum and forced margin sales, and that its core operations remain normal.
- KOS Extends Floor-Price Streak to 29 Sessions, but Not a Record: This Is the Name With the Most Dramatic Floor-Price Losing Streak in Vietnam's Stock Market History
Shares of Kosy JSC (KOS) have hit the floor price for 29 consecutive sessions, falling nearly 90% in about six weeks and wiping out thousands of billions of VND in market capitalization. The slide came as securities firms repeatedly force-sold shares held by several executives and organizations linked to Kosy. KOS has not broken the record of 34 consecutive floor-price sessions set by CDO in 2016–2017, though FTM (30 sessions, 2019) and ATG (29 sessions, 2016–2017) also had long streaks. The article notes that when margin-selling pressure hits thinly traded stocks, investors may find it very hard to exit their positions, even after steep price declines.
- KOS unexpectedly hits ceiling price after 29 consecutive floor-price sessions, record liquidity of over 74 million units
KOS (HOSE) rose to the daily ceiling price of VND 4,060 per share in the morning session on 30/10, ending a streak of 29 consecutive sessions at the floor price since 21/09, with more than 74.1 million shares matched, the highest volume in the company's history. Before that, the stock had lost more than 87% of its value, falling from VND 30,050 per share on 21/09 to VND 3,800 at the close on 29/10, which shrank market capitalisation from over VND 6,000 billion to nearly VND 880 billion. Several executives and related entities, including Chairman Nguyễn Việt Cường, were repeatedly subject to forced margin sales by securities firms, cutting his stake to 33.09% of charter capital. In its explanations, KOS said some securities firms had cut prices and demanded collateral disposal within a short period, leaving the company without time to arrange funds, and maintained that its core operations showed no unusual changes. For the first half of 2026, the company reported net revenue of VND 722 billion and profit after tax of nearly VND 15.4 billion, but has not yet published its Q3 financial statements.
- Investors bottom-fishing after stock hits floor price for 30 consecutive sessions
KOS opened the 30/10 session at the floor price of 3,540 VND, its 30th consecutive session at the floor, with the stock down about 90%. Within 15 minutes, large buy orders absorbed all floor-price sell orders, lifting the price back to the ceiling of 4,060 VND, with buy orders of about 10 million shares left unfilled. Morning volume exceeded 74 million shares, equal to 34% of the company's capital, while market capitalization shrank by over 6,000 billion VND to under 900 billion VND. Management said selling pressure came from the forced disposal of collateral at several securities firms and from market-wide momentum selling, and that core real estate and renewable energy operations remain normal. As of 13/10, Chairman Nguyễn Việt Cường held over 71.8 million shares, or 33.17% of capital, and faces heavy margin-call pressure from several securities firms.

- US Plans Unexpected Economic Boost for Russia: Europe Immediately Objects
The US is pushing to quickly restart the sale of Russian gas to Europe through the pipeline crossing Ukraine, possibly via a US intermediary, with the proceeds placed in an escrow account in a third country so Moscow cannot use them to fund the war. Washington sees this as a lever to persuade President Vladimir Putin to accept a ceasefire on energy infrastructure, and Kyiv could earn significant transit fees. However, the EU must fully end Russian gas purchases by the end of 2027, and many European leaders have said they do not want to depend on Moscow again. Before the war Russia supplied about 45% of Europe's gas, now only about 11%, while US LNG covers about 30% of demand; the Iran conflict has pushed Europe's energy spending up by about 100 billion euros (112 billion USD), and storage is about 75% full. Moscow has not yet accepted the US-backed energy-strike ceasefire effort.
- Is Australia selling its ANZAC frigate shipyard to China?
The Williamstown shipyard, the last in Victoria able to build and maintain large naval vessels and located near Port of Melbourne, is being sold to EMKC, a property fund manager partly owned by Hong Kong's EMKC Group. A company representative confirmed the purchase contract has been signed, with the value undisclosed, though the site had been listed in 2024 at an estimated AUD 200 million. The deal has raised national security concerns, as the article notes that China's national security and foreign relations law could draw interest from its intelligence agencies, and it is unclear whether the Hong Kong company holds a majority stake. The yard built all 10 ANZAC-class frigates, but most staff were laid off after its last ship was completed in 2016. The sale comes as Australia replaces ANZAC frigates with Japan's New FFM design.
- Asia stocks rise as tech gains ahead of Apple results
Most Asian stocks rose on Monday, led by technology shares, as easing oil prices supported risk appetite while investors awaited Apple's quarterly results amid concerns over heavy AI infrastructure spending. South Korea's KOSPI jumped 2.6%, with SK Hynix up 4% and Samsung Electronics up 1.5%, while Japan's Nikkei 225 pared early losses to gain 0.4%. Intel's nearly 29% plunge on Friday after a disappointing profit outlook had raised concerns about semiconductor and other AI-related earnings. Brent crude fell 2% to $111.15 a barrel and U.S. crude dropped 2.3% to $101.73 as diplomatic efforts to end the U.S.-Israeli war on Iran continued. Australia's S&P/ASX 200 bucked the trend with a 0.5% fall ahead of a Reserve Bank of Australia decision on Tuesday, where a 25 basis point hike to 4.85% is widely expected, its fifth increase this year, after inflation accelerated to 4.3% in September.
- Can SpaceX Overcome the AI Trade Sell-Off?
AI stocks have sold off as investors demand proof that huge AI infrastructure spending will pay off, with results so far mixed. SpaceX's AI sales surged 830% to $7.6 billion in the third quarter, accounting for 52% of total revenue, but capex jumped 185% to $19.6 billion, with 83% allocated to AI. Its Starlink business grew 69% to $5.2 billion, and the company expects capex of up to $40 billion this year. The stock is down about 5% from its $150 opening price and remains below its IPO price, while Alphabet fell about 10% after capex of $51.3 billion and missed sales and earnings estimates. The author considers that investor skepticism about capex could weigh on SpaceX's shares for a while.
