South Korean Stocks Soar Over 2% on Strong Tech and Auto Sector Performance; Kospi Breaks 7,800 Mark

South Korean stocks experienced a significant rebound on Wednesday, climbing over 2 percent to close above the crucial 7,800-point threshold. This robust market performance was driven by investors actively acquiring semiconductor and automotive shares, even as lingering Middle East tensions persisted ahead of the anticipated US-China summit. Despite the equity market surge, the local currency saw a decline against the US dollar.

After initially opening 1.69 percent lower, the benchmark Korea Composite Stock Price Index (Kospi) dramatically reversed its course, concluding the trading day at 7,844.01. This marked an impressive gain of 200.86 points, or 2.63 percent, for the index.

The previous day, Tuesday, saw the Kospi dip by 2.29 percent to finish at 7,643.15, ending a five-session bullish run primarily fueled by the tech sector due to profit-taking activities.

Market Dynamics: Trading Volume and Investor Activity

Wednesday’s trading volume was notably heavy, with 733.4 million shares changing hands, amounting to a substantial 49.7 trillion won ($33.4 billion). Despite the overall market rally, losers slightly outnumbered winners, with 599 declining stocks against 281 advancers.

Individual investors and institutions were the primary catalysts for the market’s strong uptick. They net purchased 1.9 trillion won and 1.7 trillion won worth of stocks, respectively. Conversely, foreign investors were net sellers, offloading a significant 3.7 trillion won in shares.

Driving Factors: Global & Domestic Sentiment Boost Kospi

Investor sentiment improved despite overnight reports of US inflation in April reaching its fastest pace in nearly three years, coupled with oil prices surpassing $100 per barrel amid dimming hopes for a Middle East peace accord. The optimism largely stemmed from expectations that the upcoming US-China summit could alleviate concerns surrounding the Iran conflict, thereby reducing global geopolitical risks.

Domestically, market sentiment also received a boost from calls by the prime minister and finance minister for Samsung Electronics’ management and labor to resume talks. These discussions aim to resolve their ongoing dispute regarding pay raises and bonus payments, following the failure of overnight mediation talks to bridge their differences on critical issues.

“Eased risks at home and abroad significantly contributed to the Kospi’s turnaround,” stated Lee Kyung-min, an analyst at Daishin Securities. “Key artificial intelligence (AI)-related stocks, including industry giants like Samsung Electronics, SK Hynix, and SK Square, played a pivotal role in leading this market resurgence.”

Further easing concerns for tech companies, President Lee Jae Myung clarified via social media that his chief policy adviser’s recent viral post regarding redistributing profits from the AI boom was a review of utilizing surplus tax revenue, not a proposal for a new levy on corporate profits. This clarification addressed earlier investor apprehension that arose on Tuesday after remarks by Seoul’s presidential policy chief, Kim Yong-beom, on profit sharing for tech companies in the AI era had weighed down on market sentiment.

Sector Highlights: Semiconductor, Auto, and Retail Lead Gains

On Wednesday, semiconductor and auto shares emerged as the biggest winners across the South Korean stock market.

  • Semiconductor & AI-Related Stocks:
    • Samsung Electronics saw its shares rise 1.79 percent to 284,000 won.
    • SK Hynix posted an impressive jump of 7.68 percent, reaching 1.98 million won.
    • AI investment firm SK Square climbed to 1.19 million won, an increase of 5.68 percent.
    • Samsung Electro-Mechanics, an electronics parts and module affiliate of Samsung Electronics, vaulted 7.41 percent to 1.03 million won.
  • Automotive Sector:
    • Top carmaker Hyundai Motor surged by 9.91 percent, closing at 710,000 won.
    • Its sister company, Kia, also advanced strongly, gaining 6.65 percent to reach 197,500 won.
  • Retail Sector:
    • Major retailer Shinsegae soared 9.29 percent to 482,500 won.
    • Lotte Shopping added 5.54 percent, closing at 160,100 won.

Notable Declines

While the market largely celebrated gains, some key companies experienced declines:

  • Defense giant LIG D&A decreased by 0.68 percent to 873,000 won.
  • Leading banking group KB Financial Group lost 1.04 percent, settling at 152,000 won.
  • In the biotech sector, Samsung Biologics decreased 2.29 percent to 1.41 million won.
  • Celltrion also dropped 1.45 percent, closing at 190,500 won.
