South Korea’s stock market suffered a sharp setback overnight, with the Korea ETF EWY falling roughly 10% after recently reaching record highs. The move reversed what many traders viewed as a bullish breakout, highlighting the risks of relying solely on traditional technical analysis in today’s markets.
The decline was reportedly triggered by speculation that SK Hynix may shift production capacity away from high-bandwidth memory (HBM), a key component used in AI data centers, toward standard DRAM products. If accurate, the report could signal concerns about future HBM demand growth. However, investors should treat the report cautiously until further confirmation emerges.
The selloff in Korea has spilled into U.S. semiconductor stocks, pressuring the broader technology sector. Leveraged semiconductor ETF SOXL and memory-focused shares are seeing significant weakness ahead of Micron’s earnings release tomorrow, an event likely to provide important clues on AI-related demand trends.
Beyond semiconductors, investors are also preparing for quarter-end portfolio rebalancing, with institutions expected to shift substantial capital from equities into bonds. Meanwhile, companies are increasingly focusing on reducing AI operating costs, driving interest in cheaper open-source models and lower-cost alternatives, including offerings from China.
Elsewhere, concerns over SpaceX valuation continue to weigh on sentiment, while renewed government support for nuclear energy and quantum computing remains a longer-term positive.
Key tickers in focus today are $EWY, $MU, $SOXL, $GOOG, and $SPCX.
