KOSPI stocks exhibited extreme volatility on July 15 and July 16, with semiconductor shares leading a 6.24% surge before reversing 6.37% the following session. Of 944 KOSPI-listed stocks, 648 declined from June 22 to July 14, with Samsung Electronics falling 25.60% and SK Hynix dropping 34.46% during the downturn. The sharp rebound concentrated in semiconductor and equipment stocks reflected valuation attraction after the selloff, according to Lee Jung-bin, research fellow at Shinhan Investment & Securities, who noted that earnings forecasts remained solid despite price corrections. The divergent recovery speeds across sectors increased stock selection difficulty, as non-semiconductor shares showed limited gains despite the broad market bounce.
