- South Korea’s KOSPI benchmark rallied 5.76% to close at 8,088.34 following a V-shaped turnaround from lows near 7,300
- Speculation surrounding Anthropic’s discussions with Samsung for custom AI chip development bolstered investor sentiment
- Memory chipmaker SK Hynix soared 10.88% during the same trading session after plummeting 14.6% previously
- Despite recent volatility, the KOSPI maintains its position as 2026’s top-performing major global index with approximately 92% gains year-to-date
Samsung Electronics shares experienced a powerful rebound during Friday’s trading session, surging 8.22% following the previous day’s steep 9.1% decline. This dramatic turnaround occurred as South Korea’s KOSPI index recovered from Thursday’s circuit breaker-triggered trading halt amid widespread market panic.
Samsung Electronics Co., Ltd., SMSD.L
The benchmark KOSPI index plunged to intraday lows around 7,300 Friday morning before executing a remarkable V-shaped reversal, ultimately finishing the session 5.76% higher at 8,088.34. The previous day’s trading had witnessed a brutal 7.89% decline — marking one of the index’s most severe single-session losses in 2026.
Market sentiment shifted dramatically following reports that artificial intelligence company Anthropic has entered negotiations with Samsung regarding the development of specialized AI processing hardware. This development provided investors with a compelling fundamental reason to re-enter positions in both Samsung and its semiconductor industry peer SK Hynix.
SK Hynix shares rocketed 10.88% higher Friday, recovering from the previous session’s punishing 14.6% crash. These two semiconductor giants represent the KOSPI’s heaviest weightings, meaning their price movements significantly influence the broader index’s direction.
Thursday’s market rout received additional downward pressure from forced liquidations in heavily leveraged single-stock exchange-traded funds. South Korea’s financial oversight authorities publicly acknowledged their concerns regarding this specific market dynamic.
AI Hardware Partnership Speculation Energizes Recovery
Friday’s impressive comeback represented more than just technical positioning. The emerging reports about potential Anthropic-Samsung collaboration on custom AI hardware provided genuine fundamental support alongside opportunistic value buying and short position covering following Thursday’s extreme fear-driven selling.
Samsung’s stock continues trading substantially below its 52-week peak of 374,500 won, suggesting potential upside remains if the artificial intelligence memory narrative maintains momentum.
The KOSPI’s extraordinary 2026 performance has been predominantly driven by the AI memory semiconductor theme. The index has delivered approximately 92% returns year-to-date — a stunning outperformance compared to every other major global equity benchmark. The S&P 500, for context, has advanced just 9.3% during the same period.
Memory Chip Mania Extends Beyond Seoul
The AI memory semiconductor rally isn’t limited to South Korean markets. American competitor Micron concluded Thursday’s abbreviated trading session down 5.5% at $975.56, caught in the broader technology sector selloff that pressured the Nasdaq Composite, which declined 0.8% to close the holiday-shortened trading week.
Micron has still delivered extraordinary 166.4% gains year-to-date, underscoring the intense investor enthusiasm surrounding memory semiconductors throughout 2026.
South Korea’s robust Friday recovery is being interpreted as an encouraging indicator for Micron when American exchanges resume normal operations Monday following the Independence Day holiday.
Friday’s sharp advances in Samsung and SK Hynix resulted from a confluence of factors including technical short covering, value-oriented buying, and opportunistic short-term capital all simultaneously pursuing the recovery momentum.
Samsung Electronics concluded Friday’s trading session 8.22% higher, while SK Hynix finished up 10.88% on identical timing.
