Popular stocks hit limit down! Major capital outflows from these stocks this week (list attached)

This week, major funds increased their positions in several leading lithium battery stocks.

Today (March 13), in the afternoon, the popular stock Guangxun Technology (002281) hit the daily limit down and remained locked at the limit until the close, with still 50,900 lots of buy orders at the end of the trading day.

Last night, the company issued an announcement regarding abnormal stock trading fluctuations, stating that recently, the company noticed online information related to sample submissions, potential customers, large orders, revenue forecasts, technological breakthroughs, and capacity. After verification, all information was found to be false.

After-hours龙虎榜 data shows that the top trading seats bought 482 million yuan and sold 1.422 billion yuan throughout the day, resulting in a net sell of 941 million yuan.

Public information indicates that Guangxun Technology is a listed platform affiliated with China Information Technology Group, a leading domestic optical communication enterprise. Its main products include optical access/data communication and optical transmission equipment, with vertical integration capabilities from chips, devices, modules to subsystems, applicable to telecom optical networks and data center networks. According to Omida data, the company ranks fourth globally in the optical device industry and holds a leading market share in transmission networks, access networks, and data communication.

Major Funds Boost Two Key Industries This Week

From March 9 to 13, the Shanghai Composite Index declined by 0.7%, closing at 4,095.45 points. According to Securities Times·Data Treasure, net outflows of major funds this week exceeded 146 billion yuan.

Dividing by Shenwan’s first-level industries, machinery equipment and non-ferrous metals saw net outflows of over 19 billion yuan; computer, communications, defense military, and electronics industries each experienced net outflows exceeding 15 billion yuan. On the inflow side, basic chemicals and household appliances saw net inflows of over 1 billion yuan, at 6.451 billion yuan and 1.072 billion yuan respectively.

CITIC Construction Investment noted that, driven by post-holiday reopening and rising oil prices, the diffusion index (the proportion of categories with weekly price increases) for the 154 tracked chemical products reached 60.39%, the second-highest point in the past decade after the energy consumption dual control in October 2021. The firm highlighted ongoing US-Iran tensions, reassessment of coal chemical energy security, and price increases and arbitrage opportunities in small chemical varieties.

On the news front, geopolitical risks pushed oil prices higher, and most coal chemical products rely on petroleum derivatives as raw materials. Under the broad oil-coal price spread, coal-based products in the industry chain benefited significantly. Rising European natural gas prices also pressured chemical costs, but additive products with low downstream cost proportions and good pricing bases, such as amino acids, vitamins, and anti-aging agents, have started to realize price increases.

Major Funds Increase Positions in Several Leading Lithium Stocks

In terms of individual stocks, 66 stocks saw net inflows of over 300 million yuan from major funds this week. Leading the list were CATL, Sungrow Power Supply, BYD, Zhaochi Co., Ltd., and Luxshare Precision, with inflows of 3.63 billion, 3.224 billion, 2.202 billion, 1.222 billion, and 1.075 billion yuan respectively.

CATL’s revenue in 2025 is projected at 4.237 trillion yuan, up 17.04% year-over-year; net profit attributable to shareholders is expected to reach 722.01 billion yuan, up 42.28%, both hitting record highs. Earlier, CATL announced a dividend plan, proposing a cash dividend of 69.57 yuan per 10 shares (tax included), with no capital reserve transfer or bonus shares. In 2025, the company’s total cash dividends and share repurchases will amount to 40.486 billion yuan, accounting for 56.07% of the net profit attributable to shareholders in the annual consolidated report.

Since March 10, CATL’s stock price has surged more than 11%.

Besides CATL, other lithium sector stocks such as Lead Intelligent, EVE Energy, Tianqi Lithium, and China Science & Technology Electric have also been favored.

Additionally, wind power and photovoltaic stocks like Sungrow Power Supply, Hengdian DMEGC, and Tongyu Heavy Industry; electronics stocks such as Huidian Electronics, Luxshare Precision, and Jiangbolong; and basic chemical stocks like Hongbaoli and Baofeng Energy have also attracted major fund inflows.

Major Funds Exit Several Leading Optical Module Stocks

On the outflow side, 99 stocks experienced net outflows of over 500 million yuan from major funds this week. Leading the outflows were Huagong Tech, Runze Technology, and Tuowei Information, with net outflows of 5.081 billion, 3.484 billion, and 3.483 billion yuan respectively; GCL System Integration, BlueFocus, China Energy Construction, Lio Co., Ltd., and Xinwei Communications followed, each with net outflows exceeding 2 billion yuan.

After the Lunar New Year, Huagong Tech experienced a continuous rise, with a total increase of over 80%, but has recently declined for two consecutive days. On February 12, Huagong Tech held its first extraordinary general meeting for 2026, approving the issuance of H-shares and listing on the Hong Kong Stock Exchange. The main purpose of issuing H-shares is to raise funds for overseas production bases and optimize shareholder structure to attract long-term foreign investment.

Huagong Tech is a leading domestic optical communication company. According to its optical module business head, orders for connection products are booked into Q4 2026, with AI high-speed optical modules operating at full capacity 24/7. During the 2026 Spring Festival, the company’s Wuhan and Thailand production bases operated at full capacity to ensure mass production and delivery of 1.6T and 800G high-speed optical modules.

Notably, other top optical module companies such as Zhongji Xuchuang, Innolux, and Tianfutong also saw major fund withdrawals, with amounts of 1.048 billion, 1.292 billion, and 897 million yuan respectively.

CITIC Construction Investment remains optimistic about the optical module industry. The firm believes that with the rapid upgrade of GPUs and ASICs, computing power continues to improve, and data transmission demand has surged. By 2026, demand for 800G optical modules is expected to grow rapidly, with shipments of 1.6T modules also increasing significantly, and R&D for 3.2T modules has already begun.
