• South Korea’s KOSPI benchmark rallied 5.76% to close at 8,088.34 following a V-shaped recovery from 7,300 lows

Samsung Electronics shares mounted an impressive comeback Friday, gaining 8.22% after experiencing a 9.1% decline in the prior trading session. This recovery mirrored a broader turnaround in South Korea’s KOSPI index, which had activated circuit breakers Thursday amid intense market-wide selling pressure.

The KOSPI benchmark touched intraday lows near 7,300 Friday morning before executing a striking V-shaped reversal, ultimately finishing 5.76% higher at 8,088.34. The previous session witnessed a brutal 7.89% decline — marking one of the index’s steepest single-day retreats in 2026.

Emerging reports suggesting AI powerhouse Anthropic is negotiating with Samsung regarding custom AI hardware development provided investors with compelling reasons to re-enter the market. This development helped propel the recovery in both Samsung and fellow semiconductor manufacturer SK Hynix.

SK Hynix shares soared 10.88% Friday, recovering from its own catastrophic 14.6% drop just one day earlier. As the KOSPI’s two largest components, these semiconductor giants significantly influence the broader index direction.

Thursday’s dramatic selloff was partially intensified by liquidation pressure in heavily leveraged single-stock exchange-traded funds. South Korea’s financial oversight authority publicly addressed concerns regarding this market dynamic.

Anthropic Partnership Speculation Energizes Recovery

Friday’s rally extended beyond simple technical retracement. The reports linking Anthropic with Samsung on bespoke hardware development provided genuine fundamental momentum alongside value-seeking and short position covering following Thursday’s panic-driven liquidation.

Samsung’s stock continues trading substantially below its 52-week peak of 374,500 won, suggesting potential for additional upside if the artificial intelligence memory narrative maintains strength.

The KOSPI’s exceptional 2026 performance has been predominantly fueled by the AI memory sector boom. With approximately 92% year-to-date gains, the index significantly outpaces every other major global benchmark. The S&P 500, for context, has advanced merely 9.3% during the same period.

AI Memory Momentum Extends Beyond Korea

The artificial intelligence memory sector rally isn’t confined to Seoul markets. American competitor Micron concluded Thursday’s abbreviated pre-holiday session down 5.5% at $975.56, swept up in the semiconductor sector weakness that pushed the Nasdaq 0.8% lower.

Micron nonetheless maintains impressive 166.4% year-to-date gains, underscoring the exceptional strength characterizing memory stocks throughout 2026.

South Korea’s robust Friday rebound is interpreted as an encouraging indicator for Micron when American exchanges resume trading Monday following the Independence Day holiday.

Friday’s advances for Samsung and SK Hynix reflected a convergence of technical short-covering, opportunistic value buying, and rapid-response capital all simultaneously pursuing the recovery trade.

Samsung’s shares settled 8.22% higher Friday, while SK Hynix posted corresponding gains of 10.88%.
