Market
KOSPI, from yesterday's (7/6) closing price of 8,051.33, plummeted to 7,389.22 (down -8.22% from the previous day) during today's session, triggering both the sidecar and circuit breaker, with trading completely halted for approximately 20 minutes. After trading resumed, it partially recovered losses to close at 7,573.97, recording a -5.93% decline from the previous day. KOSDAQ also closed lower, falling from 847.07 to 826.91, a -2.38% drop.
Supply/Demand Points
Based on the last confirmed trading day (7/6), KOSPI supply/demand showed retail investors +2.68 trillion won net buying, foreign investors -1.31 trillion won net selling, and institutions -1.46 trillion won net selling. Today's (7/7) confirmed investor-specific supply/demand figures, due to KRX data collection characteristics, are announced on the next business day and are not reflected in this update. However, according to reports, today also saw continued diverging flows with foreign investors selling and retail investors buying on margin. Samsung Electronics reportedly plummeted despite posting an all-time quarterly earnings, following Morgan Stanley's bearish outlook on memory semiconductors.
