Korea Exchange and Koscom Check data show retail investors aggressively bought
14 single-stock leveraged ETFs on July 24, with net inflows of about KRW 450
bln. Retail had been net sellers of these products over July 21–23, with
cumulative net outflows of KRW 547.17 bln. The July 24 reversal comprised net
purchases of seven Samsung Electronics single-stock leveraged products totaling
KRW 103.90 bln and seven SK Hynix products totaling KRW 350.03 bln. The buying
occurred on a day when the KOSPI fell over 5%, Samsung and SK Hynix fell about
7–8%, and the related single-stock leveraged ETFs dropped roughly 15–16%. Market
commentary notes the sharp ETF price declines likely drew dip buyers, and that
higher minimum margin requirements taking effect on July 31 may have prompted
some retail investors to increase positions ahead of tighter rules.
