South Korea’s Kospi index advanced 6.6% on Wednesday because robust earnings alongside a massive shareholder distribution from SK Hynix revived market enthusiasm for artificial intelligence equities.
SK Hynix shares advanced 11%, whereas Samsung Electronics rallied 9%. This upward momentum spilled over into U.S. premarket sessions, pushing Micron Technology (MU) and SanDisk (SNDK) up by 4% each.
These advances build upon a broader rebound across the AI industry during recent sessions, breaking weeks of downward pressure driven by market skepticism regarding the pace of AI infrastructure expansion.
Bloomberg reported that SK Hynix posted a September-quarter operating profit of 83.3 trillion won ($62.5 billion), representing a sevenfold surge that topped expert predictions by greater than 7%.
Furthermore, the semiconductor manufacturer revealed intentions to distribute an additional 60 trillion won ($45 billion) via share repurchases and dividend distributions across the remainder of the fiscal year.
Bloomberg noted that SK Hynix indicated both traditional and high-bandwidth memory production capacity is fully booked through 2029, with tight supplies projected to last until at least 2030.
These financial figures indicate that constrained memory inventories continue bolstering manufacturer profitability, despite ongoing market worries regarding the expenditures and financing associated with AI infrastructure.
Meanwhile, Bitcoin experienced a modest recovery, climbing to $81,700.
