1. 'Undervalued Debut' China's CXMT Reshuffles the Deck

- Key Summary: China's ChangXin Memory Technologies (CXMT) closed at 49.0 yuan on the 27th, its first day of trading on Shanghai's STAR Market, up 465.82% from its offering price of 8.66 yuan, reaching a market capitalization of 3.28 trillion yuan (about 712 trillion won) to become mainland China's largest company. This came after it raised 12.5 trillion won in its initial public offering (IPO) earlier this month, and its global DRAM market share also jumped from 3% in the first quarter of last year to 8% in the first quarter of this year. Amid this, news that a Chinese state-owned enterprise had begun mass production of immersion deep ultraviolet (DUV) lithography equipment on the 27th piled on, causing Korean and U.S. memory chip stocks to plunge in unison, including SK hynix (-7.47%), Micron (-2.25%) and SanDisk (-11.02%). Bloomberg also offered an assessment that CXMT had effectively "failed in its listing," saying its offering price had been set low for political reasons.

2. SK hynix Signs Long-Term Deals with 10 Clients Including Big Tech; HBM4 Yield Stabilization Boosts Production

- Key Summary: SK hynix announced at its second-quarter earnings release on the 29th that it had concluded long-term agreement (LTA) negotiations with more than 10 key clients including Big Tech firms. An LTA is a contract type that commits to transactions for up to five years, and the company plans to boost profitability by setting only base prices and including conditions to adjust actual prices in line with memory market fluctuations. Along with this, in the second half it raised HBM4 yields to the level of the previous-generation HBM3E and began full-scale production increases, and recently signed a strategic partnership worth 500 billion dollars with Nvidia. Financial information provider FnGuide forecast that SK hynix's third-quarter revenue would surpass 100 trillion won for the first time ever.

3. Chinese Tech Listings Surge 87%; Yangtze Memory, Moonshot, DeepSeek 'Big Fish' in Second Half

- Key Summary: Fundraising by companies newly listed on mainland China's stock market in the first half of this year totaled 100.5 billion yuan, surging 87% from a year earlier, consulting firm KPMG said on the 29th. As the United States tightened auditing regulations on Chinese companies listed in New York, China has responded with a strategy of dual listings on the mainland (A-shares) and Hong Kong (H-shares), and Hong Kong IPO volume also grew 92% from a year earlier. In the second half, Moonshot AI (target enterprise value of 72.22 trillion won) is scheduled to list, followed next year by Yangtze Memory (213.33 trillion won) and DeepSeek (115.21 trillion won). However, the mainland market's demanding screening and barriers to foreign capital remain high.

4. What Kind of Company Is China's DUV Maker 'Aishengna' That Triggered Semiconductor's 'Black Tuesday'

- Key Summary: The Chinese state-owned enterprise that triggered the plunge in global semiconductor stocks was confirmed to be Shanghai-based 'Aishengna,' Reuters reported on the 28th. Founded in August 2023, the company has the character of a consortium that gathered lithography equipment development personnel, and plans to produce five immersion deep ultraviolet (DUV) lithography units this year and 20 next year to supply SMIC, Hua Hong Semiconductor and CXMT. Experts interpreted this news, if true, as a signal that the U.S. technology blockade policy against China had effectively failed. However, JPMorgan predicted that immediate commercial impact would not be significant, saying small-scale production and building a mass-production system are entirely different matters.

5. 'AI-Driven Plunge' Contagion Fears…"UK Central Bank Investigating IB Concentration in SK hynix, TSMC"

- Key Summary: The Prudential Regulation Authority (PRA) under the Bank of England (BOE) is investigating investment banks' (IB) prime brokerage exposure concentrated in a small number of stocks including SK hynix, TSMC and CXMT, the UK's Financial Times (FT) reported on the 29th. Prime brokerage is a service in which IBs provide leverage to institutional investors such as hedge funds using stock portfolios as collateral, and the related market has grown rapidly along with the surge in Asian AI-related stocks. Amid this, SK hynix's share price fell more than 9% that day and Taiwan's TSMC also dropped 3.51%, continuing the AI-driven plunge in Asian stock markets. The FT also raised the possibility that Asian business revenue of major IBs including Goldman Sachs, JPMorgan Chase and Morgan Stanley could surpass their European business this year.

6. Only After 864 Trillion Won Vanished…F4 Holds Emergency Meeting

- Key Summary: The KOSPI closed at 5663.24 on the 29th, plunging 360.42 points (5.98%) from the previous trading day, with 864.5271 trillion won in market capitalization vanishing over two days. Sell-side sidecars and circuit breakers were triggered for two consecutive days in the KOSPI and KOSDAQ markets, marking the first time circuit breakers have been triggered on consecutive days in both markets. In response, the Ministry of Economy and Finance, Bank of Korea, Financial Services Commission and Financial Supervisory Service belatedly held a market situation review meeting (F4 meeting), and voices in the market are growing louder that authorities need to activate a contingency plan. Analysts say the KOSPI's plunge was driven by drops in semiconductor stocks including SK hynix (-9.61%) and Samsung Electronics (005930) (-5.23%).
