Micron and SK Hynix Shares Fall as Chip Sell-Off Deepens
Micron (MU) and SK Hynix (000660.KS) shares fell 5% on October 13, extending a five-day losing streak, as a chip sell-off deepened due to competition from Chinese manufacturer CXMT. Samsung Electronics (005930.KS) also declined 7%. CXMT's progress in memory-chip design threatens the market share of these three companies, which collectively dominate 90% of the global DRAM market. Samsung reported a record $80B Q3 profit, but sector sentiment remains weak.
