Taiwan stocks extended their slide on July 29, briefly falling below the 40,000 mark after a sharp sell-off the previous day. Finance Minister Chuang Tsui-yun told lawmakers that personnel linked to the National Financial Stabilization Fund are continuing to monitor the market, but the threshold for intervention has not yet been met. She said the sell-off is not unique to Taiwan, pointing to synchronized declines in the U.S., Japan, and South Korea, with losses concentrated in electronics and semiconductor shares. The benchmark’s weakness came after a 2,030.83-point drop on July 28, the third-largest single-day point loss on record. Memory shares were hit particularly hard after SK Hynix reported second-quarter 2026 results that came in below expectations. Several names, including Winbond, Nanya Technology, and Macronix, fell to daily limit-down levels, while other memory-related stocks dropped more than 9%. Analyst Chou Chia-ho of Lun Yuan Securities Investment Consulting said funding and margin pressure remain a key issue, warning that forced selling may continue before the sector finds a clearer bottom.

ChangXin Technology, a domestic memory chip maker listed in Shanghai under 688825.SH, made a blockbuster debut on July 27, closing at RMB 49 per share, up 465.82% from its issue price and ending the day with a market capitalization of RMB 3.28 trillion. The company set several records cited in the source material, including the largest IPO in STAR Market history, becoming the first A-share stock to open above RMB 3 trillion in market value, overtaking Industrial and Commercial Bank of China for the top spot in the A-share market-cap ranking, and posting more than RMB 100 billion in first-day turnover. Based on the closing price, one subscription lot would have generated roughly RMB 20,000 in profit. The listing also translated into large paper gains for strategic investors, public and private funds, and company insiders. NIO, which committed RMB 158 million in the strategic placement, was shown with an estimated paper gain of about RMB 740 million, while Wuhan Yibabayi Ling Enterprise Management, identified in the source as a Xiaomi subsidiary, posted a similar first-day gain. Data cited from Chinese financial media showed public funds sitting on about RMB 49.79 billion in static gains and private funds on about RMB 6.509 billion. The report also highlighted founder Zhu Yiming, multiple executives and core technical staff with holdings valued above RMB 100 million, employee incentive shares worth more than RMB 37.6 billion at the close, and the roughly RMB 49.168 billion in missed paper gains tied to Country Garden’s prior exit from a 1.56% stake.

Lianyou Metal (7610), a Taiwan-listed company focused on rare metal recycling and refining, fell limit-down for a second straight session after market concerns spread from a public security case involving the head of industry peer Jing Yuan Tungsten Cobalt. The company said its operations were unrelated to the incident, but the sell-off continued, leaving the stock at TWD 1,350, down 50% from its early-July peak of TWD 2,730. The report ties the move to broader attention on tungsten, a strategic metal used in defense, semiconductor manufacturing, and precision heavy industry. Tungsten’s 3,422°C melting point and high hardness have kept it in focus as China controls more than 80% of global production and tightens exports. ABMedia’s report also reviewed Lianyou’s business model and recent financial results. Founded in 2018, the company recycles industrial waste into sodium tungstate and cobalt sulfate, and it is described as one of the world’s top three sodium tungstate producers outside China. First-quarter 2026 gross margin reached 73.88%, while June revenue was TWD 750 million and second-quarter revenue totaled TWD 1.9 billion, both records. The article also noted that, as an Innovation Board stock, Lianyou is only open to qualified investors and trades with relatively limited liquidity.

Changxin Technology, or CXMT, drew intense market attention after its July 27 STAR Market debut, where the stock opened at 49.50 yuan against an 8.66 yuan issue price and the company’s market value climbed above 3.6 trillion yuan. At the same time, Nomura published its first coverage report, assigning a Buy rating and a 116 yuan target price, a call that quickly became one of the market’s most discussed notes. The bank’s thesis rests on capacity expansion, technology upgrades, stronger pricing, rising AI-led memory demand, and room for domestic substitution in China’s DRAM market. Nomura also projects a sharp rise in revenue and profit through 2028 and expects CXMT’s global DRAM share to increase meaningfully. Still, the report does not ignore downside factors. It highlights risks tied to potential U.S. export restrictions on equipment and materials, heavy cyclicality in the DRAM business, and the possibility that aggressive expansion across the industry could eventually outpace demand. Those concerns mirror issues already flagged in the company’s own listing documents and remain central to how investors judge whether the valuation can hold.

Odaily reported that on-chain analyst Ember said in a post on X that ChangXin Memory Technologies, or CXMT, had risen above 50 yuan. Following that move, a whale holding a short position in the stock was sitting on an unrealized loss of $3 million. The update only cited Ember’s post and did not disclose further details about the position, including its size, entry level, or the identity of the trader. The report was categorized under whale activity.

Yuanta Securities Investment Trust has denied widely shared claims on Threads that Taiwan’s 0050 exchange-traded fund is about to undergo another split, including posts saying holders who keep the ETF through the end of July could see “1 lot become 20 lots.” In a statement, the firm said the information was not official and that no 0050 split has been arranged or carried out this year. According to the report, the posts were designed to create urgency and draw investors into follow-up interactions. The usual pattern starts with social accounts following users and asking them to comment “0050” or send a private message for more details. From there, users may be pulled into investment groups and shown unidentified products or messages, with some accounts suspected of steering people toward illegal investment chat groups. The rumor gained traction in part because 0050 did complete a 1-for-4 split in 2025, giving the false claims a veneer of plausibility. Yuanta said investors should verify information such as distributions, performance, and annualized returns through the Market Observation Post System and the firm’s official website. It also said it has no connection to the accounts spreading the claims and has not authorized any third party to publish related information. For suspicious messages, the company advised investors to call its anti-fraud hotline at (02) 2777-5165.

China’s tighter export controls on tungsten, a key industrial metal used in advanced semiconductors, defense and aerospace, have drawn fresh attention to supply-chain resilience. In Taiwan, the recent incident involving the head of ammonium paratungstate, or APT, producer Jing Yuan Tungsten Cobalt has added uncertainty to the local tungsten materials chain. Against that backdrop, Lianyou Metals (7610), a company focused on tungsten and cobalt recycling and refining, has moved into the spotlight. The company buys industrial waste materials in domestic and overseas markets, then refines them into sodium tungstate and cobalt sulfate. According to the source article, Lianyou is now one of the world’s top three sodium tungstate producers outside China. Its business model has also supported strong profitability because scrap acquisition costs are lower than primary ore mining costs. Financial figures cited in the report show Lianyou posted a 73.88% gross margin in the first quarter of 2026 and earnings per share of NT$10.87. June consolidated revenue reached NT$750 million, up 22% from a month earlier and 555% from a year before. Second-quarter consolidated revenue came in at NT$1.9 billion, rising 92% quarter on quarter and 450% year on year, both record highs. The company said demand from AI, aerospace, defense and high-end automation supported the result, while new capacity from its Pingnan No. 2 plant is expected to lift sodium tungstate output in the third quarter.

A homicide investigation in Taiwan has drawn attention to a company with an unusual position in the island’s industrial supply chain. Jing Yuan Tungsten Cobalt Resources, based in Pingtung, is described in the source report as Taiwan’s only producer of ammonium paratungstate, or APT, a key intermediate material in the tungsten industry. The company’s 56-year-old head, surnamed Huang, was found dead at his residence with visible injuries and signs that his hands may have been bound. Police have sealed off the scene, reviewed nearby surveillance footage, and started examining the victim’s personal and business relationships. The case is being handled as a suspected homicide, though the motive, number of people involved, and whether the case is tied to financial, debt, or business disputes have not been determined. The report says there is currently no evidence linking the killing to China’s tighter controls on tungsten-related exports, rising global tungsten prices, or broader competition over strategic metal supply chains. Even so, the company’s role in producing APT has put the case under a brighter spotlight, especially as tungsten remains important for cutting tools, aerospace, defense equipment, electronics materials, and semiconductor manufacturing.
