SK Hynix shares plunge 30% in second flash crash in a week

South Korean chipmaker SK Hynix saw its shares plunge 30% on Nextrade in a flash crash, marking the second such incident in a week. The fall was triggered after just 11 shares traded at 1.168 million won each, before prices recovered during the pre-open session. A similar crash last week briefly impacted nearly $60 million in derivative contracts.
