📉 1. Massive Sell-off of Global Semiconductor and Chip Stocks, Korean KOSPI Triggers Circuit Breaker

1. Severe Fluctuations in Korean Stock Market

Index Plunge: On July 28, the Korean KOSPI index closed down 10.84% (at 6023.66 points), with an intra-day maximum decline of 11.3%, triggering the circuit breaker mechanism (the 8th time this year), marking the largest single-day drop since March. This month, the index has cumulatively dropped about 29%, retreating about 34% from the June high.

Samsung Electronics plummeted 14.4% in a single day (the largest single-day drop since October 2008), while SK Hynix fell 14.7%. Foreign investors net sold about 5 trillion won in a single day.

On July 29, KOSPI continued to drop over 2%, breaking below the 5895 point level, creating a new low in more than three months.

2. U.S. Semiconductor Sector and Micron (MU) Under Pressure

Sector Divergence: U.S. stocks presented structural rotation, with the Dow Jones index rising 1.03%, while the Philadelphia Semiconductor Index (SOX) plummeted 4.5% (at 11035 points).

Micron Technology (MU) Performance: Closed down 8.85% on July 28 (at $820.53, a single-day drop of $79.67), with trading range between $789.09–$848.36, and a total market capitalization of about $927 billion.

Associated Stocks Weakening: Stocks in the semiconductor and storage supply chain, such as Sandisk, NVIDIA (NVDA), AMD, and Intel, faced significant adjustments simultaneously.

3. Fluctuations in Derivatives and High-Leverage Contracts

As the underlying assets (Samsung, SK Hynix, Micron, etc.) experienced severe fluctuations, perpetual contracts on cryptocurrencies (such as SNDKUSDT, SKHYUSDT, KORUUSDT) faced sharp declines of 10%–17%, with high-leverage long positions facing concentrated liquidation.

📈 2. Ethereum (ETH) Low Point Correction and Spot ETF Fund Flows Turn Positive

Price Correction Performance

As of July 27, 2026, Ethereum (ETH) traded at $1,950–$1,970, rebounding about 25% from the early July low (around $1,570).

Continuous Inflows into Spot ETH ETF

After approximately 8 weeks of consecutive net outflow, the fund flow for U.S. spot Ethereum ETFs significantly improved in mid to late July.

Institution Distribution: Incremental funds are primarily dominated by the ETHA fund under BlackRock.

Corporate and Institutional Holding Dynamics

With macro inflation data (CPI) cooling and phased recovery in risk preference, corporate entities like Bitmine, associated with Tom Lee, continue to increase their ETH holdings as financial reserves. Currently, institutional holdings are close to 4.8%–5% of ETH's global total supply.
