August 31st Closing Market Conditions: KOSPI's Dramatic Rebound After Intraday 3% Plunge and the Next Scenario Hidden in Foreigners' Futures Buying

Summary

The August 31 KOSPI rebounded dramatically from its 6547 midday low to close up about 0.46% near 6820, while KOSDAQ sharply trimmed losses. Kim Jang-yeol argues the Jackson Hole rate fear was not confirmed and highlights memory supply shortages to 2028, Amazon's Anthropic catalyst, and Korean PCB/CCL strength. Lee Kwon-hee sees foreign futures buying and corporate buybacks as market support, and points to ESS battery names, LG group strength, and the upcoming KOSDAQ revitalization plan. Main macro risks remain US labor data and FOMC rate interpretation.
