Key Takeaways:
South Korea's Kospi Composite Index surged nearly 10% to KRW 8,430 on June 12, putting it within striking distance of its all-time high of KRW 8,925.
The Kospi jumped 9.8% to KRW 8,430 in Thursday trading, extending a dramatic V-shaped recovery after the index plunged more than 8% on June 8 in its worst single-day rout since October. The benchmark now sits just 5.9% below the record KRW 8,925 set earlier this year, having recouped nearly all of last week's losses in three sessions.
"The speed of this rebound reflects a market that overshot to the downside and is now repricing on renewed conviction in the AI trade," said Sarah Lin, equity markets analyst at Edgen. "The Kospi's heavy weighting in semiconductors means it moves in lockstep with global tech sentiment, and that sentiment flipped sharply this week."
Technology stocks powered the rally, with computer chip and memory makers leading gains. SK Hynix, which on June 8 announced plans to partner with Nvidia on data center infrastructure, surged 15.8% on June 9 and continued climbing through the week. Samsung Electronics advanced 8.8% on June 9 and added further gains in subsequent sessions. The broader semiconductor-heavy index has more than doubled the performance of most regional peers this year.
The rally coincided with a broader recovery in global technology shares after last week's selloff. On Wall Street, the S&P 500 added 0.3% to 7,405.73 on June 8, while the Nasdaq composite climbed 0.9% to 25,929.66, recovering some of the ground lost in the 2.6% drop on June 5 that was its worst since October. Micron Technology rose 9.9% after sliding 13.3% the prior session, and Marvell Technology climbed 9.6% after S&P Dow Jones Indices said the semiconductor company would join the S&P 500 index.
Regional markets followed the Kospi higher. Taiwan's Taiex advanced 2.8% on June 9, driven by gains in computer chip giant TSMC. Tokyo's Nikkei 225 gained 1% to 64,654.22, with computer chip equipment maker Tokyo Electron rising 7.5%. Hong Kong's Hang Seng index was flat at 24,631.52, while the Shanghai Composite added 0.7% to 3,988.46.
The Kospi's surge comes as foreign investors rotate back into Korean equities after last week's selloff. The index's 10% single-day gain is among its largest on record and underscores the extreme volatility driven by the concentrated tech exposure in Asian markets. South Korea's benchmark is dominated by Samsung Electronics and SK Hynix, which together account for more than 30% of the index's market capitalization, making it acutely sensitive to shifts in global semiconductor demand and AI-related capital expenditure cycles.
The next catalyst for the Kospi will be the Bank of Korea's monetary policy decision later this month, as well as second-quarter earnings from Samsung Electronics expected in early July. Traders will also watch for any escalation in geopolitical tensions involving Iran, which pushed oil prices higher last week and contributed to the initial selloff. Brent crude fell back to $93.09 per barrel on June 9 after briefly topping $98, while US benchmark crude settled at $89.88.
