Private equity funds have become a key force behind sector rotation on South Korea's KOSPI as retail and foreign investor trading contracts. Their share of average daily KOSPI trading value reached 1.89% in August through the 28th, the highest level of the year, up from 1.73% in July and the low-to-mid 1% range recorded during the first half. These funds, which include private equity and hedge funds, can adjust positions more quickly than pension funds or insurers because they are not bound by predetermined asset-allocation guidelines. Their buying has centered on cosmetics, construction, energy and nuclear power-related shares, including Kolmar Korea, Cosmax, APR, Doosan Enerbility, OCI Holdings, Hanwha Solutions and GS Engineering & Construction. Retail and foreign investors have instead favored semiconductors and IT, shipbuilding and defense, and securities. Retail investors' average daily KOSPI trading value through August 28 was 16.6146 trillion won (approximately $12.1 billion), less than half June's 35.458 trillion won (approximately $25.9 billion), while foreign trading was about 19 trillion won (approximately $13.9 billion), down from roughly 37 trillion won (approximately $27.0 billion) in June. The rotation has produced unusually broad participation: on the 28th, the KOSPI fell 1.79% to 6,788.88, yet 640 stocks advanced against 238 decliners; on the 24th, 579 stocks rose even as the index dropped 3.12%. Construction gained approximately 40% over the past month, outperforming the KOSPI by 20 percentage points, while machinery and equipment and medical and precision instruments also outperformed. Analysts say improving earnings forecasts in refining, shipping, shipbuilding, home appliances, electrical equipment and machinery could support a broader rally, but warn that gains may represent valuation rotation if earnings do not catch up. Interest rates and foreign capital flows remain central risks. On the latest session described, the KOSPI initially fell more than 3% on semiconductor weakness before recovering to close up 0.46% at 6,820.02; Samsung Electronics and SK Hynix turned positive, while LG Electronics surged 7.44% after news of a planned large-scale chiller plant in Virginia.
