KOSPI Falls 8%; Know Why Trading Halted for 20 Minutes


    By Dalal Street Investment Journal (DSIJ)

    Summary :

     

    South Korea's KOSPI plunged more than 8%, triggering a 20-minute trading halt. Weak investor reaction to Samsung Electronics' earnings, a sharp sell-off in semiconductor stocks, employee protests, and fresh geopolitical concerns after an LNG carrier attack in the Gulf of Oman weighed heavily on market sentiment.

    KOSPI Slides 8% Amid Samsung Earnings Shock and Global Risks

    South Korea's equity market saw one of its sharpest declines of the year on Tuesday after the benchmark KOSPI index slumped more than 8% during intraday trade. The steep fall forced the exchange to activate a 20-minute trading halt, as panic selling swept across the market.

    The KOSPI dropped to an intraday low of 7,404.48 before trading was temporarily suspended. The halt came into effect at 1:57 p.m. Korea Standard Time (KST) after the index breached the exchange's circuit breaker threshold. Trading resumed at 2:17 p.m. KST.

    Earlier in the session, authorities had also activated a sell-side circuit breaker, which briefly paused program sell orders in an attempt to slow the pace of the decline. It was the sixth time this year that the exchange had invoked a circuit breaker.

    Samsung Electronics Earnings Disappoint Investors

    A key reason for the fall was the reaction to Samsung Electronics' preliminary second-quarter earnings. While the company announced strong financial results, they did not live up to market expectations. According to the company, revenue from operations amounted to 171 trillion KRW, lower than the anticipated 173.9 trillion KRW. Operating profit came in at 89.4 trillion KRW, slightly higher than the projected 87.3 trillion KRW.

    Market participants reacted negatively to the lower-than-expected revenue figures and questioned whether the recent surge in artificial intelligence stock prices was justified. 

    Moreover, market sentiment was further weighed down by employee protests at Samsung Electronics. The protests centred around the company's internal incentive policy.  As a result, the stock fell below the 300,000 KRW mark, adding pressure on the broader market. It fell as much as 9.75% during early trade, slipping to 287,000 KRW.

    Semiconductor Stocks Felt the Heat

    The weakness was not limited to Samsung Electronics. Selling spread across the semiconductor space as investors reduced exposure to technology stocks.

    SK Hynix shares fell more than 10% during the session and traded at 2,095,000 KRW. The stock came under pressure as investors exited chipmakers following Samsung Electronics' earnings update.

    Gulf of Oman Attack Fuels Risk-off Sentiment

    "During the trading session, reports surfaced that an LNG tanker was targeted in the Gulf of Oman, a vital shipping route located in the Strait of Hormuz. This brought new worries regarding energy security and geopolitical issues. Consequently, investors pulled capital out of risk assets, triggering another round of selling in the technology-dominated markets like South Korea.
