Samsung Electronics mounted an impressive comeback Friday, rallying 8.22% following Thursday’s steep 9.1% decline. This rebound formed part of a sweeping recovery throughout South Korea’s KOSPI, which had activated trading halts during Thursday’s intense market downturn.

The KOSPI plummeted to approximately 7,300 during Friday’s early trading before executing an impressive V-shaped turnaround, ultimately finishing 5.76% higher at 8,088.34. Thursday’s trading had witnessed a 7.89% slide — ranking among the index’s most severe single-session losses this year.
News emerged that artificial intelligence company Anthropic has entered discussions with Samsung regarding the development of specialized AI hardware, providing investors with renewed optimism. This development helped propel the recovery for both Samsung and semiconductor competitor SK Hynix.
SK Hynix soared 10.88% Friday, recovering from its devastating 14.6% drop during the previous session. These two semiconductor giants dominate the KOSPI’s composition, making their movements critical to overall index performance.
Thursday’s market turmoil was intensified by heavy selling pressure in heavily leveraged single-stock exchange-traded funds. South Korea’s financial oversight authority issued public warnings regarding this market dynamic.
Friday’s rally extended beyond mere technical correction. The reports surrounding potential Anthropic-Samsung custom hardware collaboration provided substantive justification alongside value-seeking purchases and short position closures following Thursday’s extreme selling pressure.
Samsung’s stock continues trading significantly beneath its 52-week peak of 374,500 won, suggesting potential for additional gains if the AI memory narrative maintains momentum.
The KOSPI’s exceptional 2026 performance has been almost exclusively driven by the AI memory sector boom. The benchmark’s approximately 92% annual gain eclipses every other major global index. In contrast, the S&P 500 has advanced a modest 9.3%.
The AI memory sector rally transcends Seoul’s borders. American competitor Micron concluded Thursday’s trading down 5.5% at $975.56, swept up in the widespread semiconductor selloff that pressured the Nasdaq, which declined 0.8% to end the abbreviated holiday week.
Micron maintains an impressive 166.4% year-to-date advance, underscoring the remarkable strength of the memory sector throughout 2026.
South Korea’s robust Friday recovery provides an encouraging indicator for Micron heading into Monday’s U.S. market reopening following the Independence Day holiday.
Friday’s dramatic movements in Samsung and SK Hynix resulted from a convergence of technical short-covering activity, opportunistic value buyers, and short-duration investment funds simultaneously pursuing the recovery momentum.
Samsung’s shares finished Friday’s session 8.22% higher, while SK Hynix concluded up 10.88% on the same trading day.
