South Korea's red-hot stock market index, the Kospi, is experiencing a volatile start to the week, dropping 8% on Monday, before gaining 8% on Tuesday. The Kospi dropped sharply at Monday's open, losing around 700 points, or 8%, as investors took stock of a US market sell-off at the end of last week, which particularly affected tech stocks. On Tuesday, it recovered all those losses, closing at 8,096 points, a gain of 8.2% on the day, and around 50 points above its Monday opening price.
