1.2 Million South Korean Traders Hit With Margin Calls in July Crash

MarketWatch reported July 17 that roughly 1.2 million South Korean retail traders received margin calls during a crash that rippled across Asia. That exceeds 3% of the country's adult population — an unusually broad hit for a single margin-call event in a developed market. A margin call forces investors to deposit cash or sell assets when borrowed positions lose value.
