Korean Stocks Plunge as Samsung and SK Hynix Slide. Is It Time to Buy the Dip?
South Korean equities opened the week with a sharp sell-off on Monday, October 12. The benchmark KOSPI plunged 3.65% to close at 6,384.24, marking its first close below 6,400 in roughly two months and its largest single-day drop in about a month. The tech-heavy KOSDAQ followed suit, tumbling 4.83% to 849.19.
The Damage in Semiconductors
The two memory-chip giants bore the brunt of the selling. Samsung Electronics fell 4.39% to close at 250,500 won, equivalent to approximately $187.60 at the current exchange rate of 1,335.1 won per dollar. SK Hynix dropped 4.52% to 1.6 million won, or roughly $1,198.50 in dollar terms. This decline occurred despite Samsung reporting record-breaking earnings, a fact that has puzzled many market participants.
What Drove the Sell-Off?
Several factors combined to pressure the market:
1. Foreign Selling: Foreign investors net sold approximately 2.02 trillion won on the day and have been net sellers for five consecutive sessions, offloading roughly 8.6 trillion won over that period.
2. Buyback Support Fading: Market analysts noted that Samsung and SK Hynix may have completed their treasury stock purchases, removing a key source of demand.
3. AI Profitability Concerns: During the Korean market holiday, doubts expanded in the U.S. about artificial intelligence profitability following news that OpenAI's annualized revenue was below market expectations.
4. Middle East Tensions and Inflation: Renewed Houthi attacks on Saudi Arabia's main airport pushed oil prices higher, fueling inflation concerns and complicating the Federal Reserve's policy outlook.
Is This a Buying Opportunity?
The bull case for accumulating Korean tech stocks on weakness rests on several points:
· Goldman Sachs views the KOSPI's divergence from the Philadelphia Semiconductor Index (SOX) as a positioning washout rather than a cycle top. The firm noted that forward earnings expectations remain solid, with HBM4 capacity ramp-up and equipment shortages expected to sustain AI infrastructure demand through 2028.
· Korean tech stocks are trading at multi-decade low valuations, which Goldman cited as a reason to accumulate high-conviction memory and tech leaders during significant discounts.
· Samsung's record earnings suggest the fundamental business remains strong, even as the stock price faces selling pressure.
The bear case, however, warrants consideration:
· Foreign outflows show no signs of reversing. Yuanta Securities analyst Lee Jae-won noted that "the biggest concern for the domestic market is not semiconductor earnings but foreign investor supply and demand".
· The KOSPI has broken below its 100-day moving average, a technically significant level, while the 200-day average barely holds.
· Valuation alone is not a catalyst. As one analyst put it, "solid fundamentals being confirmed and foreigners immediately returning to buy Korean stocks are separate issues".
Key Levels to Watch
· KOSPI Support: 6,300–6,350 (psychological and technical zone)
· Samsung Electronics:$183.50–$187.25
· SK Hynix: $1,161–$1,198.50
The Bottom Line
The Korean market is caught between strong semiconductor fundamentals and heavy foreign selling pressure. The sell-off appears driven more by positioning, macroeconomic headwinds, and a fading buyback catalyst than by any deterioration in the underlying chip cycle. For long-term investors, Goldman's thesis of a positioning washout rather than a structural top offers a compelling framework. However, the absence of a near-term catalyst for foreign inflows suggests patience may be required.
