South Korea’s KOSPI falls more than 5%, triggering sell-sidecar
South Korea’s KOSPI share index fell sharply on Oct.
13, and the exchange triggered a sell-sidecar at 9:47 a.m.
The index was down 5.03% at 6,062.86 at the time described.
A sell-sidecar temporarily stops program sell orders for five minutes after KOSPI 200 futures fall by at least 5% for one minute.
The drop came amid weakness in US chip and memory stocks overnight, including shares of Intel and Micron.
Investors were also concerned about Chinese chipmaker CXMT’s progress in DRAM memory and its plan to introduce a next-generation server product by the end of the year.
The news raised worries that increased memory chip supply from China could put pressure on South Korean shares, including Samsung Electronics and SK Hynix.
