US Market Analysis & Korea Daily Briefing — 2026-07-01
Yesterday’s US Market Recap
1. S&P 500 and Nasdaq Post Best First-Half Performance US markets closed higher on the final trading day of June, fueled by a rebound in large-cap semiconductor and tech stocks. The Dow Jones Industrial Average hit an all-time high on June 30 (local time), rising 0.3% to finish the first half with an 8.8% gain. Meanwhile, the S&P 500 rose about 14% and the Nasdaq jumped 19.6% over the same period, marking their best first-half performance in five years.
2. The Double-Edged Sword of Semiconductor Trends On July 1 (local time), New York markets plummeted due to weakness in the semiconductor sector. Shares of memory chip manufacturers like Micron tumbled more than 10%, erasing the Dow's late-session gains and dragging the Nasdaq down as well. Large-scale semiconductor investment announcements from Korea have sparked concerns about the end of the memory supercycle, leading to mixed market sentiment.
3. 10-Year Treasury Yields Stabilize The US 10-year Treasury yield remains relatively stable at 4.38% as of June 26, while the 2-year yield stands at 4.07%.
Key Korean Market Themes and Issues
Theme 1: Volatility in Equipment and Materials Stocks Following Semiconductor News Following announcements of massive investments by major domestic semiconductor firms, US semiconductor equipment stocks rallied, pushing the Philadelphia Semiconductor Index up by over 3%. While this signals a positive outlook for the global supply chain, it has simultaneously triggered fears that the memory supercycle may be nearing its end.
Theme 2: Transition to Rotation – Shipbuilding, Defense, and Power Equipment in Focus Starting in July, the market is expected to shift away from the semiconductor-centric trend toward a rotation strategy, with momentum spreading to sectors like shipbuilding, defense, and power equipment. Experts suggest that the government's "Great Leap Forward for Korea" policy and related industrial support will drive this sector rotation.
Theme 3: Concentration in Small-Cap Stocks and Disclosure Reliability Issues On July 1, KOSPI saw buying concentrated in individual small-cap stocks, leading to increased volatility among top-traded shares. At the same time, reliability concerns are surfacing in the KOSDAQ market as companies repeatedly retract announcements regarding supply contracts or financing plans.
Stocks to Watch Today
1. Kumho Electric (Wire/Power Equipment Sector) With expectations for a shift toward a rotation market, power equipment stocks are gaining attention. The stock was among the top-traded issues on July 1 and is expected to benefit from upcoming government power and energy policies.
2. Shipbuilding and Defense-Related Stocks (Including Kumho Construction and other ceiling-priced stocks) Experts are highly optimistic about the upside for the shipbuilding and defense sectors, with some going so far as to suggest that investors who wait too long might miss the window for gains starting in July. Stocks like Kumho Construction have already hit their daily price limits, and further profit opportunities are anticipated as government policies begin to roll out.
3. Daewon Cable (Materials/Equipment and Wire Sector) This stock is expected to benefit from two fronts: the strength of semiconductor materials/equipment stocks following recent investment news, and the broader sector rotation. It showed strong performance and ranked among the top-traded stocks on July 1.
