*CIRCUIT BREAKER TRIGGERED AFTER S. KOREA'S KOSPI PLUNGES 8% *KOREA'S KOSPI EXTENDS DROP TO 10% AFTER TRADING RESUMES The chart shows that the South Korean KOSPI stock index has doubled since last August (green) and has already corrected 17% from Friday's high (red), including a 10% correction today. This market is not for the faint of heart. South Korea's market is retail-dominated. It is estimated that up to 70% of its trading is retail, compared to about 20% for the NYSE. For years, South Korea was the world's largest equity options market by contract volume, even larger than the United States. This is a remarkable fact for a mid-sized economy. This is what retail-dominated markets do. They don't rally, they double. They don't correct, they crash. South Korea imports 94% of its oil, with 75% coming from the Middle East. So, it is easy to see why its "degens" are panicking.(Jim Bianco)
