Breakthrough High by KOSPI – Targeting Short-cover Stocks (Park Hyun-sang)
Market strategist Park emphasizes that along with strong foreign purchases, the unwinding of short positions through short covering (short-covering) by short sellers also contributed to the rally. This mechanism helped even previously neglected sectors such as secondary batteries catch up in the bullish momentum.
