AI Podcast
Japanese and South Korean stock markets closed lower on May 28. The Nikkei 225 fell 0.47% and the KOSPI Index dropped 0.53%. Profit-taking pressured the Nikkei, with SoftBank Group and Tokyo Electron declining. Semiconductor stocks showed mixed performance, though passive components like Taiyo Yuden and Murata Manufacturing hit record highs. The KOSPI saw significant intraday losses before recovering, driven by SK Hynix's 2.07% rise to a record close, reflecting strong HBM technical barriers. Samsung Electronics fell 2.44%, contrasting with SK Hynix, and LG Energy Solution surged over 15% on an ESS contract.

The KOSPI Index plummeted by more than 3% intraday, breaking below the 7,900-point threshold, but heavyweight semiconductor stocks attracted dip-buying capital, driving a significant narrowing of the index's losses.
SK Hynix closed up 2.07%, hitting another record closing high and bringing its year-to-date gain to 251.61%, decoupling from the weak broader market. Samsung Electronics fell 2.44% under pressure, highlighting a significant divergence between the two memory giants. LG Energy Solution surged over 15% after signing a 2.4 trillion won energy storage system (ESS) supply contract, making it one of the day's standout heavyweight performers.
The two memory giants, Samsung and SK Hynix, have a combined weight of over 50% in the KOSPI. Samsung Electronics' pressure that day was interpreted by the market as a continued digestion of approximately 5.28 trillion won in foreign sell-offs from the previous week. In contrast, SK Hynix's gain against the trend reflects the market's differentiated pricing of HBM technical barriers.
Furthermore, the listing of 18 leveraged and inverse single-stock ETFs on May 27 further intensified capital rotation and volatility among individual stocks.
