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.

- 25 Consecutive Limit-Down Sessions: Provincial Real Estate Firm Stirs Market
Kosy (HOSE: KOS) closed at 5,050 dong on 23 October, its 25th consecutive limit-down session, down more than 82% from 32,950 dong on 16 September, and its market capitalisation fell from about 7,133 billion dong to 1,257 billion dong. The family group of Chairman Nguyễn Việt Cường holds over 134 million shares, or more than 62% of the company, and some of these shares are pledged as collateral for bank loans. From late September to mid-October 2026, securities firms carried out forced sales of over 561,000 of Cường's shares, nearly 763,000 shares linked to Kosy Real Estate and about 4,700 shares linked to Leo Regulus. Forced-sale attempts for over 8.6 million shares held by Vice Chair Nguyễn Thị Hằng and 9 million shares held by Deputy General Director Nguyễn Thị Phương Thảo failed due to weak demand.

- Doctorate-Holding Chairman Repeatedly Hit by Forced Margin Share Sales
Kosy Chairman Nguyễn Việt Cường has had shares sold under margin forced liquidation again, the second time in under a month, as KOS extends a run of limit-down sessions.

KOS closed at 5,050 VND on 23 October, its 25th consecutive limit-down session and more than 82% below 32,950 VND on 16 September. Kosy attributed the pressure to weak liquidity, selling sentiment and some brokers cutting margin lending ratios and liquidating positions, while its reviewed H1 2026 net profit of over 15 billion VND, up about 121%, was only near 13% of its full-year plan.
- Chairman With a PhD Sees Shares Force-Sold by Securities Firm

A related entity, Kosy Real Estate Investment Co., Ltd., also had 8,000 shares force-sold on September 29 and from October 1 to 5. KOS has hit the floor price for 17 consecutive sessions, closing at 8,960 dong, with 75.6 million shares (about 35% of the company's total) offered at the floor and almost no buying demand. Kosy attributes the slide to momentum selling and to some brokers cutting margin lending ratios and forcing sales, while stating that its core real estate, renewable energy and project operations remain on plan. Its reviewed mid-year 2026 consolidated financial statements show revenue of nearly 723 billion dong (up 9%) and after-tax profit of over 15 billion dong (up about 121%), only about 13% of the 120 billion dong full-year target.

- Electricity Prices Could Fall from November 1
Households and businesses may receive electricity price cuts for 5 months starting November 1. On October 27, Deputy Prime Minister Nguyễn Văn Thắng asked Tập đoàn Điện lực Việt Nam (EVN) to urgently review and cut costs, prepare a plan to lower average retail electricity prices, and review a proposal to set the special consumption tax on gasoline to 0%. According to the Statistics Office (Cục Thống kê), residential electricity accounts for about 4.8% of the CPI basket, so a price cut could help ease inflation pressure and support growth. In the first 8 months of 2026, EVN reported profit of over 12,000 billion VND and had cleared its accumulated losses under consolidated financial statements by the end of June, which provides room to cut prices. The Ministry of Industry and Trade has asked EVN to finalize the plan and will give its opinion, and if the matter exceeds its authority, it will report to the Government.
