■ KOSPI Records Largest-Ever Drop: The KOSPI closed at 8,203.84, down 910.71 points (9.99%) from the previous trading session, marking its largest decline on record. Profit-taking in semiconductor stocks combined with losses on leveraged products, and while foreign investors and institutions net sold 4.1393 trillion won and 4.5289 trillion won respectively, retail investors net bought 8.5398 trillion won, their largest purchase on record.
■ Big Tech Shifts Fundraising Structure: Major U.S. technology companies that boosted shareholder value through share buybacks are pivoting toward fundraising through large-scale IPOs and capital increases. While the returns of the M7 have stagnated this year, investment returns are dispersing toward industries benefiting from AI infrastructure, such as semiconductors and power equipment.
■ Call to Foster Indirect Investment and ISA: Hwang Sung-yeop, chairman of the Korea Financial Investment Association, diagnosed that the excessively high proportion of retail investors in the domestic stock market makes increased volatility inevitable. He emphasized that, alongside expanding the share of institutional investors, the country should establish an indirect investment culture by fostering ISAs as a “fourth-tier pension” following the National Pension, retirement pensions, and personal pensions.

– Key Summary: The KOSPI closed at 8,203.84 on Tuesday, down 910.71 points (9.99%) from the previous trading session, setting a new record for the largest decline by margin. The nearly 10% drop came just a day after the index recorded an all-time high (9,114.55) the previous day, with market capitalization evaporating in a single day on the securities market reaching 742.7573 trillion won. With the top four semiconductor stocks (SK hynix (000660.KS), Samsung Electronics (005930.KS), SK Square (402340.KS), and Samsung Electro-Mechanics (009150.KS)) accounting for 61.7% of the KOSPI, Samsung Electronics fell 12.31% and SK hynix fell 12.47%, recording their largest declines since the 2008 financial crisis. The average decline of single-stock leveraged ETFs (exchange-traded funds) reached -25.6% for SK hynix and -24.6% for Samsung Electronics, while revisions to U.S. Federal Reserve rate-hike forecasts by Bank of America (BofA) and Deutsche Bank also pressured investor sentiment.
2. The Subtle Signal Sent by Mega IPOs
– Key Summary: SpaceX’s largest-ever initial public offering (IPO) and Alphabet’s $80 billion capital increase show that major U.S. technology companies have pivoted from share buybacks to large-scale fundraising. As Big Tech pours enormous capital into building data centers and AI infrastructure, the benefits are spreading to related industries such as semiconductors and power equipment. While the returns of the M7 (Magnificent 7) have stagnated this year, the rest of the Standard & Poor’s (S&P) 500 companies recorded relatively solid performance. Meanwhile, structural concerns have been raised that large IPOs shift the risk of founders and early investors onto general investors, and analysts say that for Anthropic and OpenAI, both expected to go public in the second half, demand for early investors to recoup their investments has been reflected in part. Korea’s stock market has a relatively favorable supply-demand environment given its expanded share buybacks and limited large IPOs, but the extreme polarization between semiconductors and non-semiconductors is deepening investors’ discomfort.
– Key Summary: Hwang Sung-yeop, chairman of the Korea Financial Investment Association, pointed out on Tuesday at the association’s office in Yeouido, Seoul, that the high proportion of retail investors in the domestic stock market is a structural cause of increased volatility, calling for an expanded share of institutional investors and the establishment of an indirect investment culture through pensions. “There was a 75% gain last year and about a 120% gain this year. I wonder if such a thing could ever happen in the history of capital markets,” he said, predicting that while there is room for further gains, ups and downs along the way are inevitable. He also said of single-stock leveraged products, “I have concerns about how the market will turn out,” and rebutted the estimate by Financial Supervisory Service Governor Lee Chan-jin that related fees amounted to 5 trillion to 10 trillion won, saying, “Since May 27 until now, it has been around 50 billion won.” He also proposed fostering ISAs (Individual Savings Accounts) as a “fourth-tier pension” following the National Pension, civil servant pensions, retirement pensions, and personal pensions, emphasizing that split buying and installment buying are investment principles in volatile markets.

4. Yen Hits Lowest in Two Years… U.S.-Japan Hold “Late-Night Emergency Meeting”
– Key Summary: As the yen-dollar exchange rate rose to the 161.9 yen range, hitting its lowest level in two years since July 2024, Japanese Finance Minister Satsuki Katayama and U.S. Treasury Secretary Scott Bessent held a late-night online consultation. The exchange rate stabilized to 161.08 yen within an hour after reaching 161.93 yen, a psychological resistance line, and as the timing of the consultation coincided with the point when the yen’s decline halted, the market sees that either currency intervention or a “rate check” by U.S. foreign exchange authorities took place. Japanese authorities have set the high-161 yen range as their final line of defense and are making every effort to stabilize the currency, but with expectations of a Fed rate hike gaining momentum, the U.S.-Japan interest rate gap is cited as the fundamental cause of yen selling, and the prevailing view is that the effect of official intervention will be limited.
5. Micron Forms Memory-AI Design “Alliance” with Anthropic… Concerns Over Circular Trading Illusion
– Key Summary: U.S. memory chipmaker Micron and AI company Anthropic have established a partnership spanning from joint research on memory and storage technology to strategic investment. Anthropic raised $65 billion (about 99.98 trillion won) in its Series H round at a valuation of $965 billion (about 1,484.36 trillion won), and through this agreement Micron aims to improve AI infrastructure performance and power efficiency and enhance the economics of tokens (the smallest unit by which AI models process language). Micron is also expanding the adoption of Anthropic’s generative AI model “Claude” across its operations, while participating as a strategic investor in Anthropic’s Series H investment round. However, since the structure has Micron’s invested funds flow back into purchases of Micron products, some point out the possibility of a circular trading illusion that inflates corporate value by exaggerating external demand.
6. Borrowing 31 Trillion Won Right After Listing… SpaceX Busy with Refinancing
– Key Summary: Aerospace company SpaceX decided to issue corporate bonds of at least $20 billion (about 31 trillion won) with maturities of 5 to 30 years, about ten days after conducting a 130 trillion won IPO. This is refinancing to repay the $20 billion bridge loan (a short-term temporary loan) used in March this year to repay the debt of X (formerly Twitter) and xAI, and global investment bank (IB) Oppenheimer expects SpaceX to accumulate $400 billion in net debt by 2031. When news of the bond issuance broke, the 10-year U.S. Treasury yield breached the psychological ceiling of 4.5% again at 4.51%, and the 30-year yield also approached the resistance line of 5.0% again at 4.94%, sending ripples across the bond market. That day, SpaceX shares plunged 16.43%, evaporating $400 billion (about 615 trillion won) in market capitalization in a single day, the second-largest single-day market cap decline in the history of the New York stock market since Nvidia following the DeepSeek shock in January last year.
