South Korea's KOSPI Plunges 7.89% on July 2, Rebounds 5.76% Next Day, Triggering Investor Regret

According to Financial News, South Korea's KOSPI index fell 7.89% on July 2, 2026, dropping to 7,648.09 from a record high of 9,114.55 on June 22, before rebounding 5.76% to 8,088.34 on July 3. Semiconductor stocks experienced similar volatility: Samsung Electronics fell 9.06% on July 2 and rose 8.22% the following day, while SK Hynix declined 14.57% before gaining 10.88%.

The sharp swings have intensified "profit-taking regret" among retail investors. According to research by the Capital Market Research Institute, individuals who lock in gains are experiencing post-sale regret when stock prices continue climbing, leading to concerns about missed upside and potential re-entry at higher prices.
