Samsung Electronics and SK Hynix both showed up at a presidential briefing in Seoul on Monday with massive chip investment announcements. The markets didn’t care.
Samsung dropped 5.3% to 321,500 won. SK Hynix fell 3.4% to 2,583,000 won. The KOSPI itself slipped to 8,258 from 8,411. Not exactly a vote of confidence.
The numbers were impressive on paper. Samsung Group presented roughly 1,000 trillion won in planned spending. SK Group followed with another 1,000 trillion won. Combined, that’s about $1.3 trillion directed at new semiconductor fabs, AI data centers, and chip cluster development over the next decade.
So why the selloff? A few things stacked up. Global tech sentiment has been sour. South Korea’s market triggered circuit breakers twice last week on fears about AI chip valuations. Samsung and SK Hynix together make up roughly 42% of the KOSPI, so when chip stocks bleed, Seoul bleeds harder. Retail investors who borrowed heavily during recent rallies are now facing compounding losses.
Then there’s the regulatory angle. The Korea Exchange scrapped its planned launch of weekly options contracts tied to Samsung, SK Hynix, Hyundai Motor, and LG Energy Solution. Regulators pulled the plug after retail investors flooded into daily double-leveraged ETFs, pushing KOSPI volatility to record highs. Removing that product took a key tool away from short-term traders and hit speculative appetite immediately.
Middle East tension didn’t help either. The US struck Iranian military targets over the weekend, though both sides have since agreed to halt attacks and meet in Doha on Tuesday.
Sometimes a $1.3 trillion announcement is just a number. The market wanted to see execution, not promises.
