2. Fundamental Analysis: Why Did This Happen?
SK Hynix’s performance in the first half of 2025 was very positive, driven by the rapid growth of the AI market and surging demand for HBM. Positive factors include technological leadership with HBM3E mass production and HBM4 development, recovery in the DRAM and NAND sectors, maintaining a solid market share, active R&D investment, and a stable financial structure. However, macroeconomic uncertainty and intensifying competition remain potential risk factors.
3. Future Outlook and Investment Strategy: What Should Investors Do?
The net selling by foreign investors in after-hours trading represents a short-term supply burden. However, considering the growth of the AI market and SK Hynix’s strong fundamentals, this could be a buying opportunity. The growth of high-value-added products centered around HBM and the recovery of the DRAM and NAND markets will support SK Hynix’s mid- to long-term growth.
