Following U.S. memory semiconductor company Micron's announcement of earnings that exceeded market expectations along with a positive future outlook, domestic semiconductor-related stocks showed a collective rally on the 25th. This is interpreted as a result of expanding demand for AI server high-bandwidth memory (HBM) and expectations for a memory industry recovery stimulating investor sentiment.

Micron recorded revenue of $41.46 billion in the third quarter of its fiscal year (March–May), demonstrating significant year-over-year growth. In particular, demand for AI server HBM and DRAM drove the earnings improvement, and the company provided next-quarter guidance that exceeded market expectations, creating a positive ripple effect across the global semiconductor sector.

In the domestic stock market as well, buying interest continued from large-cap semiconductor stocks to equipment and distribution companies.

As of the morning, SK Hynix was trading at 2,774,000 won, up 194,000 won (7.52%) from the previous trading day, showing a strong upward trend. As the company is considered a key supplier in the AI memory market, Micron's strong performance heightened expectations for direct benefits.

Samsung Electronics also traded at 353,500 won, up 1,300 won (3.82%), reflecting expectations for a memory industry recovery. The market is focusing on the possibility that DRAM price recovery and the expansion of the HBM business will lead to future earnings improvements.

Semiconductor equipment manufacturer Hanmi Semiconductor recorded a price of 278,000 won, up 8,000 won (2.96%). Forecasts that demand for TC bonder equipment, necessary for expanding HBM production, will continue supported investor sentiment.

Mirae Semiconductor, a specialized semiconductor distribution company, traded at 20,750 won, up 350 won (1.72%). Expectations for growth in downstream industries, driven by the expansion of the AI and high-performance semiconductor markets, were reflected in the stock price.

Techwing, a specialized test equipment company, recorded a price of 53,950 won, soaring 4,050 won (8.12%), marking the highest gain of the day. Expectations for expanded memory semiconductor production and increased demand for inspection equipment are analyzed to have driven the buying trend.

The market assesses that Micron's earnings are not simply positive news for an individual company, but a signal that an AI-centered memory super cycle is underway. Accordingly, expectations are growing for earnings improvements across the entire domestic semiconductor ecosystem, including HBM, advanced packaging, and test equipment.

However, investors are keeping an eye on future memory price trends, the pace of global AI investment, and U.S. big tech's data center investment plans as key variables that will determine whether the semiconductor sector will continue its upward trend.
