| Date | Post |
|---|---|
| Fri, September 18, 2026 | Shenyang Blower Works Group (Shengu Group) <601091>, a Shenyang state-owned maker of large equipment including centrifugal and reciprocating compressors and nuclear reactor main pumps, was the Chinese stock most talked about online on September 18, 2026. Background: The company listed on the Shanghai Stock Exchange main board on September 17 at an IPO price of 4.39 yuan and closed its debut day up 373.8% at 20.80 yuan. On its second trading day, September 18, it opened 28% below the prior close, then rebounded sharply, at one point rising more than 297% intraday, prompting the Shanghai exchange to suspend trading accounts flagged for abnormal activity. It closed at 57.77 yuan (+177.74%), with a market capitalization of about 180 billion yuan. In its own risk announcement, the company disclosed a static P/E ratio of 242.96x (versus an industry average of 41.74x) and a price-to-book ratio of 26.06x (versus 3.50x), warning of the risk of a sharp pullback after the rapid short-term rally. |
| Thu, September 17, 2026 | Shanghai Yahong <603159>, a Shanghai-based manufacturer and seller of molds and dies, was the Chinese stock most talked about online on September 17, 2026. Background: The stock resumed trading on September 17 after a suspension, opening locked at the daily limit-up, then plunging to the daily limit-down within minutes, before rebounding back near the limit-up within about 20 minutes. It closed at 24.34 yuan (+2.53%), with a market capitalization of just under 3.5 billion yuan. The swing followed a share-transfer announcement the previous night: existing shareholders Ningsheng Group, Xie Yaming and Xie Yue agreed to sell a combined 29.99% stake (about 41.986 million shares) to Shanghai Feike Investment for 900 million yuan, shifting the company's actual controller from Sun Lin to Li Gaiteng, founder of Flyco Electrical Appliance, known as China's "domestic razor king." As a small-cap "clean shell" stock, it also drew speculation about a possible asset restructuring (M&A). |
| Wed, September 16, 2026 | Aohong Electronics <605058>, a Changzhou-based manufacturer that makes, develops and sells printed circuit boards (PCBs), was the Chinese stock most talked about online on September 16, 2026. Background: The stock closed at 44.33 yuan (+9.99%) on September 16, hitting its fourth consecutive daily limit-up and pushing its market capitalization to about 6.4 billion yuan. Among the 64 A-share stocks that hit their daily limit that day, it stood out as the stock with the longest limit-up streak. Its cumulative gain over the five trading days since September 11 topped 40%. On September 15 the company issued an abnormal stock-price-movement announcement warning of the risk of a sharp pullback after a rapid short-term rally, while stating that its core business and operating environment had not materially changed. The same announcement disclosed that its first-half 2026 net profit attributable to shareholders fell 17.89% year on year, and net profit excluding non-recurring items fell 38.73%. |
| Tue, September 15, 2026 | Sinovatio Technology <002912>, a Shenzhen-based information security company specializing in AI security and network content security systems, was the Chinese stock most talked about online on September 15, 2026. Background: The stock opened locked at the daily limit on September 15 and closed at 28.45 yuan (+10.02%), marking its fourth consecutive daily limit-up and pushing its market capitalization to about 4.9 billion yuan. The rally came after reports that Nvidia, Palantir and Booz Allen Hamilton had asked OpenAI and Anthropic to scale back or halt use of their most advanced AI models, which fueled AI-safety concerns and sent the broader network-security concept sector sharply higher, with several stocks hitting their daily limit. The company runs an AI-governance business for enterprise clients built around its "AI WorkForce" platform, though that business accounted for less than 2% of its first-half 2026 revenue. |
| Mon, September 14, 2026 | Fujian Mindong Electric Power <000993>, a Fujian-based regional utility operating hydro, wind and solar generation plus energy storage regulation, was the Chinese stock most talked about online on September 14, 2026. Background: The stock closed at 15.27 yuan (+10.01%) on September 14, hitting its fourth consecutive daily limit-up and pushing its market capitalization to about 7 billion yuan. Among the 57 A-share stocks that hit their daily limit that day, it stood out as the stock with the longest limit-up streak. The rally was driven by brokerage views that improving water inflows in the Dadu and Yalong river basins point to higher hydropower output, and that rising coal prices make hydropower's cost advantage more pronounced. The company also reported first-half 2026 revenue of 237 million yuan and net profit attributable to shareholders of 29.41 million yuan, while Fujian's designation as China's first pilot province for integrated "source-grid-load-storage" development provided additional policy support. |
| Fri, September 11, 2026 | Jiangxi Copper<600362>, China's largest copper producer, was the Chinese stock most talked about online on September 11, 2026. Background: On September 10 it was reported that the White House had put its copper import tariff plan on hold, on concern that the measure could push up manufacturing costs and offset the benefit of supporting the domestic mining industry. LME copper plunged USD 534 to USD 14,234 a tonne that day and COMEX copper fell 4.7%, while the October COMEX-LME spread narrowed by about USD 200 to minus USD 20. In response, the company's Hong Kong-listed shares closed down 9.19% on September 11, with copper stocks among the day's biggest decliners; MMG fell 8.20% and CMOC 7.73%. In the A-share market, Jingyi Co. hit limit-down while Northern Copper, Western Mining, Yunnan Copper and Sinosteel Engineering all fell more than 5%. The Shanghai Composite ended down 1.18% at 3,888.11 on turnover of RMB 1.97 trillion, with more than 4,800 stocks declining. |
| Thu, September 10, 2026 | Bank of Nanjing<601009>, a city commercial bank in Jiangsu Province, was the Chinese stock most talked about online on September 10, 2026. Background: The A-share market was weak that day, with the Shanghai Composite down 0.43%, the Shenzhen Component down 0.77% and the ChiNext Index down 0.49% on turnover of RMB 1.6471 trillion; 955 stocks rose while 4,512 fell. Bank shares bucked the trend, and the stock gained more than 3% to set a record high, with Bank of Jiangsu, Bank of Hangzhou and Bank of Chengdu also reaching record highs. The catalyst was the Ministry of Finance's announcement that it will soon issue RMB 300 billion of special treasury bonds to inject a combined RMB 360 billion into eight central financial institutions, including up to RMB 100 billion for ICBC and up to RMB 160 billion for Agricultural Bank of China. Analysts estimate the replenishment of core tier-one capital could support asset expansion of up to about RMB 4 trillion. In addition, at least 20 A-share listed banks disclosed 2026 interim dividend plans totaling about RMB 266.1 billion in cash, of which the six largest banks accounted for a record RMB 221.0 billion. |
| Wed, September 9, 2026 | Hangzhou Bai Da Group<600865>, a department store, hotel and commercial property operator in Hangzhou, was the Chinese stock most talked about online on September 9, 2026. Background: The stock hit its daily limit again that day for a fifth consecutive session since September 3, making it the A-share market's leading stock by number of consecutive limit-ups. Its cumulative gain from the September 2 close was 61.09%, with an average turnover rate of 8.46% over the period. In an announcement the same day, the company warned of overheated market sentiment and irrational speculation, said the sharp short-term gain carried a risk of subsequent decline, and stated that there had been no material change in its main business and no matters requiring disclosure that had not been disclosed. Factors cited by the market included a revaluation of the Hangzhou Department Store property it holds in the city's core commercial district, an 18.22% year-on-year increase in hotel business revenue, and gains from disposing of Bank of Hangzhou shares equivalent to more than 10% of the prior year's net profit. Its trailing P/E ratio stood at 206.48 times as of September 7. The Shanghai Composite rose 0.28% that day, with 48 stocks hitting their upper limit. |
| Tue, September 8, 2026 | Gansu Yasheng Industrial Group<600108>, a modern agriculture group engaged in forage grass, potatoes and seed corn, was the Chinese stock most talked about online on September 8, 2026. Background: The stock locked limit-up from the opening bell for a fourth consecutive session, its fifth limit-up in the past nine trading days. Unfilled buy orders at the limit price exceeded RMB 800 million, the stock was up more than 67% year to date, and market capitalization passed RMB 10 billion. The company stated in an announcement that it is not aware of any undisclosed information that could materially affect its share price. The catalyst was the joint release on September 7 by the Ministry of Agriculture and Rural Affairs and five other departments of an implementation plan to prioritize agricultural and rural development and improve the rural revitalization investment mechanism. Rising international sugar prices added support: the Thai Sugar Millers Corporation indicated output next season could fall below 10 million tonnes, and the FAO's global food price index for August reached its highest level since December 2022. COFCO Sugar, Baolingbao and Dunhuang Seed also hit their limits. The Shanghai Composite rose 0.20% on turnover of about RMB 1.96 trillion. |
| Mon, September 7, 2026 | Innolight Technology<300308>, a leading optical transceiver maker, was the Chinese stock most talked about online on September 7, 2026. Background: Goldman Sachs initiated coverage of the company's H-shares that day with a Buy rating and 12-month price targets of HKD 3,267 for the H-shares and RMB 2,645 for the A-shares, implying about 224.9% upside from a reference price of RMB 814. The bank noted that demand for optical modules is accelerating as AI infrastructure is upgraded, and that OpenAI's GPT-6 Astra has shifted the focus from cost reduction to capability improvement, raising computing requirements and optical module specifications. It projects the global optical module market to expand from USD 37.6 billion in 2025 to USD 148.5 billion in 2028. The A-shares rose more than 10%, ranking first by turnover across both exchanges, and market capitalization returned above RMB 1 trillion. The H-shares gained more than 13% intraday, while Eoptolink rose 8.08% and T&S Communications 7.36%. The ChiNext Index closed up 3.41%. |
| Fri, September 4, 2026 | New Hope Liuhe<000876>, a major animal feed and hog producer, was the Chinese stock most talked about online on September 4, 2026. Background: The A-share market was soft that day, with the Shanghai Composite down 0.3%, the Shenzhen Component down 0.79%, the ChiNext Index down 0.78% and the STAR Composite down 2.16% on turnover of RMB 2.03 trillion. Pork-related shares bucked the trend, and the stock surged in the afternoon to close limit-up. Xinwufeng, Luoniushan, Zhenghong Technology, Tianbang Food and Bangji Technology also hit their limits. The catalyst was tightening supply: National Bureau of Statistics data showed the national breeding sow herd stood at 37.80 million head at the end of the second quarter of 2026, down 3.20% from the previous quarter and within 0.8% of the Ministry of Agriculture and Rural Affairs' target of 37.50 million head. Because sow herd reductions feed through to hog supply roughly 10 months later, the market increasingly views a supply turning point in the hog cycle as near. Computing hardware and semiconductor shares corrected, with Hua Hong Semiconductor down more than 8% and Inspur locking limit-down. |
| Thu, September 3, 2026 | CXMT<688825>, China's largest DRAM maker, was the Chinese stock most talked about online on September 3, 2026.

Turnover was RMB 11.163 billion, second in the A-share market behind Innolight's RMB 17.691 billion. The catalyst was the August 29 announcement by Changxin Memory that its LPDDR6 had entered full mass production, with a peak rate of 12,800 Mbps and a maximum capacity of 16GB, described as the world's first commercial deployment of an LPDDR6 product. It will debut in the Xiaomi 18 Fold foldable handset due to be unveiled in September. Xiaomi's in-house XRing O3 chip became the world's first processor to support LPDDR6, and Lei Jun offered his congratulations, saying this is only the beginning. Across the A-share market that day, the Shanghai Composite rose 0.02% and the ChiNext Index rose 0.01% on turnover of RMB 1.76 trillion, while more than 3,500 stocks declined. |
| Wed, September 2, 2026 | Inner Mongolia First Machinery Group<600967>, an armored vehicle maker under China North Industries Group, was the Chinese stock most talked about online on September 2, 2026. Background: With tensions in the Middle East escalating, defense-related shares bucked the wider A-share decline that day and the stock locked limit-up for a second consecutive session. Among Shenwan secondary industry groups, Ground Weaponry II led with a 6.48% gain. Great Wall Military Industry, Jianshe Industry and Boyun New Materials also hit their limits, while Shengnan Technology rose 30%, Litong Technology more than 17% and Qifeng Precision more than 14%. On September 1 local time, President Trump announced that U.S. forces had struck Iranian air defense positions, radar systems and maritime targets over roughly six and a half hours, and Iran's Revolutionary Guard retaliated with ballistic missiles and drones. WTI crude rose 5.2% to USD 90.22 a barrel and Brent rose 4.6% to USD 94.65. The broader market was weak, with the Shanghai Composite down 0.97%, the Shenzhen Component down 1.88% and the ChiNext Index down 2.39%; 54 stocks hit their upper limit and agricultural shares slumped. |

Background: Agricultural planting shares surged that day, and the stock recorded its seventh limit-up in the past 12 trading sessions. Across the A-share market, 86 stocks hit their upper limit and none hit the lower limit, with Wanxiang Denong logging its eighth limit-up in 11 sessions and Xinsai Shares its fourth in a row. The rally was driven by rising grain prices: Chicago wheat futures were up 54.5% year to date at a three-year high, and conflict in the Black Sea region was reported to have severely damaged grain export capacity. NOAA also put the probability of a very strong El Nino in the autumn and winter of 2026 at 95%, sharpening focus on food security. Among seed companies, Shennong Seed Industry, Agricultural Development Seed Industry, Denghai Seeds and Yuan Longping High-Tech all hit their limits. Separately, the company issued an unusual share price movement announcement on August 20, stating that it expects a loss for the first half of 2026 and that it is not aware of any undisclosed material matters. |
