South Korea's KOSPI hits record above 9,000, then tumbles in chip-led swings

South Korea's KOSPI has swung violently in late June, topping 9,000 for the first time on June 25 before sliding 5.8% to 8,411 by June 27. The benchmark earlier suffered a near-10% single-day drop on June 23 amid an MSCI upgrade setback and tax fears. The moves track global tech sentiment and heavyweight chip stocks Samsung and SK Hynix, which dominate the index.
