South Korea's KOSPI index plunged 9% on July 28, breaking below 6,200 for the first time since April. The Korea Exchange triggered both the sell-side sidecar and circuit breaker mechanisms, halting program sell orders for 20 minutes. Chip stocks bore the brunt. SK Hynix tumbled over 12%, Samsung Electronics dropped more than 10%. The selloff followed a brutal session for U.S. semiconductors — the Philadelphia Semiconductor Index fell over 2%, with SanDisk down 11% and Nvidia off 5%. The trigger: CXMT's debut in China spooked markets over potential disruption to the memory chip oligopoly. Concerns over AI investment returns, peaking memory prices, and fresh supply from CXMT converged in a single session.

KOSPI Dropped 9% in a Single Session. The Memory Trade Just Hit a Wall
South Korea’s KOSPI index dropped 9% on July 28 and went below 6,200 for the time since April. The drop was so big that the Korea Exchange turned on both the sell-side sidecar and the circuit breaker stopping program sell orders for 20 minutes. This was not a day when all the markets were pulling back. It was a move against the companies that are at the center of the global memory and AI hardware supply chain.
Where the Damage Concentrated
Chip stocks took the hit. SK Hynix dropped than 12%. Samsung Electro

South Korea’s stock market margin balance has dropped to its lowest level since April.
According to recent data, the total margin debt in South Korea’s stock market continues to decline, reaching the lowest point in nearly four months.

While SK Hynix took the #1 spot in terms of common shares, Samsung Electronics still retains a slight edge as South Korea's largest overall corporate entity if you combine its common shares with its separate preferred shares. However, on the main KOSPI ticker index, SK Hynix is now recognized as the market's primary bellwether stock. #SKHynixTopsKOSPIByMarketCap #GateCompletesDividendDistribution ##IsraelStrikesIranBTCPlunges
