Global Market: South Korean shares surge 6% as SK Hynix earnings fuel AI chip rally
Economic Times 1 hr ago·28 Oct 2026, 4:54 am
South Korean stocks jumped nearly 6% on Wednesday, led by SK Hynix and Samsung Electronics. The rally was triggered by strong earnings reports and growing optimism regarding artificial intelligence (AI) demand for memory chips. SK Hynix, a major supplier of high-bandwidth memory used in AI, reported a significant jump in profits, while foreign investors injected over $440 million into the market. This surge highlights the critical role of South Korea in the global technology supply chain.
For investors, this event underscores the growing importance of the semiconductor sector as a key driver of the AI revolution. The sharp rebound in South Korean equities suggests that the market is reacting positively to the strong earnings outlook for chipmakers. This momentum is likely to spill over into other global tech stocks, making the semiconductor industry a focal point for investors monitoring the AI trend.
Moving forward, investors should watch for further earnings updates from major chip manufacturers and global demand trends for AI-related hardware. The sustainability of this rally will depend on whether the current optimism regarding AI demand translates into sustained sales and profitability for tech companies.
