- After recording the fifth-largest single-day drop in history, South Korea's KOSPI index attempted to rebound but lacked momentum. The Bank of New York Mellon pointed out that the niche retail buying that previously drove the index to new highs is weakening due to regulatory authorities' lukewarm attitude towards leveraged ETFs.
- The global chip semiconductor sector is highly crowded, with the market focusing on Micron Technology's (MU:US) earnings report, which will be released after the US stock market closes. The focus is on its long-term supply agreements and prepayment arrangements with major clients.
- The yen traded around 160.56 against the dollar during the Asian trading session. Japan's Ministry of Finance plans to study how to improve the management of its $1.3 trillion foreign exchange reserves. The market is wary of potential joint intervention actions by Finance Minister Katsuyuki Katayama and US Treasury Secretary Scott Bessent.
Retail Leverage Withdrawal Drags Down Korean Stock Rebound
The KOSPI index, dominated by chip stocks, briefly surged in early trading on Wednesday before falling into volatility, erasing gains by midday in Seoul. The latest analysis from the Bank of New York Mellon indicates that the retail capital momentum that has driven the Korean stock market higher in recent months is undergoing marginal changes. Particularly, after Korean regulators showed cautious and lukewarm attitudes towards popular leveraged ETF products, retail investors' enthusiasm for going long has significantly waned. With the marginal weakening of retail buying, confidence in a bullish rebound is notably lacking after the KOSPI index experienced the fifth-largest single-day drop in history in the previous session, presenting an overall weak consolidation pattern.
Micron Earnings as a Litmus Test for Crowded Semiconductor Trades
In the Taipei market, shares of chip manufacturing giant TSMC (2330:TW) fluctuated lower, reflecting cautious attitudes ahead of key catalysts. Micron Technology's (MU:US) upcoming earnings report is set to become the next core indicator for assessing sentiment and capital flows in the Asian and global chip sectors. According to a June survey of fund managers by Bank of America, as many as 80% of professional investors surveyed believe that going long on semiconductors is currently the most crowded trade in global financial markets, a record high reading. Given the current high concentration of market positions and valuation levels, investors' tolerance for performance or guidance below expectations has significantly decreased.
Supply Chain Long-term Agreements and AI Cycle Assessment
The market's focus on Micron Technology's earnings is not limited to short-term earnings per share and revenue but also on whether it can announce long-term supply agreements with key downstream clients and related prepayment arrangements. This directly relates to the capacity lock-in of core hardware such as high-bandwidth memory (HBM) and the visibility of future cash flows. Despite crowded positions, the aforementioned fund manager survey also shows that more than half of respondents insist that the current AI investment cycle is still in a boom phase, not yet entering the frenzy, profit-taking, or panic stage before an asset price bubble bursts. If Micron's guidance exceeds expectations, it may attract funds to reprice tech stocks.
Risk of Japan-US Joint Intervention and Reassessment of Foreign Reserve Management
In the G10 currency market, the yen remains under pressure at a high of 160.56 against the dollar during the Asian session, close to the warning level that previously triggered intervention. As Japan's Finance Minister Katsuyuki Katayama and US Treasury Secretary Scott Bessent hold online talks this week, expectations for possible joint currency market intervention to support the yen have significantly increased. A draft report obtained by Reuters shows that the Japanese government plans to study how to improve the management of its $1.3 trillion foreign exchange reserves, which are currently mainly composed of US Treasury bonds. If core macro variables or intervention actions materialize, global cross-asset liquidity may face short-term reassessment.
