The KOSPI index fell 4.52% to close at 7,730.82 on March 10, 2024 [1].
The sharp decline reflects growing instability in global markets, as geopolitical friction and technology sector volatility trigger automatic circuit breakers in Seoul.
Market volatility led to the triggering of a sell-sidecar during the session [1]. This followed a buy-sidecar that had been triggered the previous trading day [1]. At one point during the day, the index dipped to an intraday low of around 7,400 [1].
Investor activity showed a stark divide between institutional and retail traders. Foreign investors net sold 2.7717 trillion KRW [1], while institutions net sold 2.2673 trillion KRW [1]. Conversely, individual investors net bought 4.8612 trillion KRW [1].
Analysts said external pressures were the primary drivers of the slump. The combination of escalating tensions between the U.S. and Iran, and a downturn in U.S. technology stocks, weighed heavily on investor sentiment [1].
An anchor for YTN News said the signs of intensifying conflict between the U.S. and Iran, along with the weakness of U.S. tech stocks, appeared to have a significant impact [1].

The rapid succession of a buy-sidecar followed by a sell-sidecar indicates extreme short-term volatility in the South Korean market. The heavy net selling by foreign and institutional investors, offset only by retail buying, suggests a lack of confidence among professional managers regarding geopolitical risks and the stability of the global tech sector.
