KOSPI plunged almost 9% - its third biggest drop since the Lehman crash - tumbling to close below its 7,000-handle for the time since early May, dipping below its 100DMA (@ 6874), after experiencing a 7th Circuit Breaker for the year. There have been 13 market-wide trading halts since the system's inception in 2000; this means that more than half of all market-wide halts this century have occurred this year.
