[Key Issue Briefing]
■ AI Chip Debate: A U.S. Treasury bubble warning and JP Morgan's optimism are colliding head-on over the sustainability of the AI rally, widening the gap in market views. Earnings releases and executive conference calls from major chipmakers such as TSMC and ASML, continuing through mid-month, have emerged as a watershed that will determine the direction of the AI market.
■ Deepening Yen Weakness: As the yen's value plunged to its lowest level in 40 years, hedge funds' speculative yen short positions ballooned to their largest in 19 years, since 2007, just before the Lehman Brothers collapse. Market distrust of the Bank of Japan's slow tightening pace, combined with the Takaichi Sanae cabinet's expansionary fiscal stance, is strengthening expectations of prolonged yen weakness.
■ Domestic Market Concentration: As extreme capital concentration into AI chip and policy-beneficiary stocks continues, the gap between the share prices of the bio and secondary battery sectors and brokerages' target prices is widening to a record level. Despite signs of easing in the electric vehicle chasm (a temporary demand slowdown) and strong global battery shipments, funds are flowing only toward the leading stocks of the AI rally, deepening polarization between sectors.
[News of Interest to Global Investors]
- Key Summary: U.S. Treasury analysts reportedly included in a draft confidential report a warning that if the AI market fails to monetize, a shock similar to the dot-com bubble collapse could spread across data centers, the private credit market, and chip manufacturers. Morgan Stanley also raised market caution, estimating Big Tech's global AI investment budget at $805 billion in 2026 while recommending a reduction in chip exposure. In response, JP Morgan presented an optimistic view that global chip stocks will set all-time highs during the second half of 2026, arguing that new AI chip supply facilities are difficult to secure by 2028 and that chronic supply shortages support pricing power. Experts say that as interpretations emerge suggesting the record earnings of Micron and Samsung Electronics (005930.KS) are a late-cycle sign relying on price increases rather than volume growth, the major companies' conference calls continuing through mid-month are the key variable that will determine the direction of the AI market.
- Key Summary: Samsung Electronics announced preliminary results of 171 trillion won in revenue and 89.4 trillion won in operating profit for the second quarter of 2026, with quarterly operating profit reportedly exceeding as much as 106 trillion won when incentive provisions are excluded. The memory division's operating margin was about 83%, surpassing Micron (81%) to record the industry's highest level, and Samsung Electronics is assessed to have solidified its status as a "swing producer" (a key producer that regulates market supply) that has a decisive influence on price and supply-demand trends in the global memory market, backed by monthly wafer production capacity of 650,000 to 700,000. Meanwhile, Samsung Electronics is maintaining its technological lead by becoming the world's first to mass-produce sixth-generation high-bandwidth memory (HBM) HBM4, which is used in Nvidia's next-generation AI accelerators, and by being the first to supply samples of seventh-generation HBM4E. The industry projects that as the production capacity of the three memory companies will only expand in earnest after 2028, Samsung Electronics will continue its record of exceeding 100 trillion won in quarterly operating profit in the second half as well, and that surpassing 140 trillion won per quarter next year is also possible.
3. Tightening Sluggish While Coffers Open...Yen Selling Largest in 19 Years
- Key Summary: Bloomberg reported, citing U.S. Commodity Futures Trading Commission (CFTC) data, that hedge funds' yen short positions reached 138,000 contracts, the largest since June 2007 in 19 years, a result of surging speculative selling as the yen's value plunged to its lowest in 40 years. The Bank of Japan raised its base rate to 1% for the first time in 31 years and signaled the possibility of further hikes, but the dominant concern in the market is that it is in a "behind the curve" state (a monetary policy that lags market conditions) with a tightening pace slow relative to prices and exchange rates. In addition, as new U.S. Federal Reserve Chairman Kevin Warsh signaled a tightening stance, dollar strength also fueled yen weakness, with bets on a strong dollar reaching about $40 billion (about 61 trillion won), the highest since December 2015. Within Japan, too, as concerns grow that the funding for the Takaichi Sanae cabinet's expansionary fiscal policy is unclear, pessimism is emerging that yen weakness could deepen to 170 yen per dollar.

4. Neglected Bio and Secondary Battery Stocks...Target Prices Grow More Distant
- Key Summary: According to FnGuide, the current share prices of 231 of the 233 KOSPI stocks—99.1%—fell below brokerages' target prices, and 136 stocks had a divergence rate exceeding 50% from their target prices. In the bio sector, large-cap stocks such as Yuhan (000100.KS) (88.2%), SK Biopharmaceuticals (326030.KS) (71.3%), Hanmi Pharmaceutical (128940.KS) (54.0%), and Celltrion (068270.KS) (48.6%) fell far below their target prices, while in the secondary battery sector, the divergence rates of L&F (066970.KQ) (135.5%), POSCO Holdings (005490.KS) (81.3%), Samsung SDI (006400.KS) (76.0%), and LG Energy Solution (373220.KS) (62.5%) stood out. Heo Hye-min, a researcher at Kiwoom Securities (039490.KS), analyzed, "In the first half, the pharmaceutical and bio sector experienced extreme supply-demand neglect and was the weakest even in the returns of major countries' Morgan Stanley Capital International (MSCI) healthcare index," adding, "For a trend-based rebound, it must ease concentration and prove global competitiveness." Despite the easing phase of the EV chasm and strong global battery shipments, as capital concentration into AI chip and policy-beneficiary stocks continues, expectations for earnings improvement in the secondary battery and bio sectors are not being sufficiently reflected in share prices.
5. Embracing SpaceX...Will Space ETFs Ride a "Rebound Rocket"?
- Key Summary: With SpaceX officially joining the Nasdaq 100 index on Monday, mechanical buying of up to 41.2 trillion won is estimated to occur through inflows of global passive (index-tracking) funds that track the Nasdaq 100 and Russell 1000. This inclusion is a case applying the "Fast Entry" system introduced by Nasdaq this year, and SpaceX showed extreme share price volatility after listing at an offering price of $135 on the 12th of last month, soaring to as high as $225.64 intraday before falling to $147.11 following the announcement of a plan to issue $20 billion in corporate bonds. Among domestic space exchange-traded funds (ETFs), TIGER US Space Tech recorded the poorest return at -35.45% over the recent one-month period before the inclusion, while ACE US Space Tech Active (-22.60%) and KODEX US Space Aerospace (-20.04%) also posted double-digit declines. However, the industry is offering cautious views that the index inclusion effect may already be substantially priced in, so the scale of initial passive fund inflows may be more limited than the market expects.
