Gotrade News - SK Hynix posted record quarterly profit but missed analyst forecasts, sending its shares sharply lower on Wednesday. The miss lit the fuse on a broader Asian semiconductor rout that dragged South Korea's KOSPI down 12.3%.
Investors read the shortfall as a sign that even booming AI-memory demand may not keep outrunning sky-high expectations. For US-listed chip investors, the selloff hit memory peers Micron and SanDisk and pressured Nvidia.
Key Takeaways
SK Hynix's operating profit surged 557% year-on-year to a record 60.54 trillion won, yet fell short of the roughly 64 trillion won consensus.
The stock fell 8.98% in regular trading and plunged as much as 20% intraday as the market-wide selloff intensified.
The KOSPI dropped 12.3% to 5,283.12, its second straight session halted by a circuit breaker.
US-listed memory names slid, with Micron down 8.85% and SanDisk down 14.25%, while Nvidia also declined.
A Record Quarter That Still Disappointed
SK Hynix reported its best-ever quarter and still could not satisfy the market. According to Investing.com, revenue reached a record 79.32 trillion won, up 257% year-on-year and 51% from the prior quarter, while operating profit surged 557% to 60.54 trillion won at a 76% operating margin. The trouble was the bar: per Investing.com, those figures still undershot analysts' consensus of roughly 64 trillion won in operating profit and 84 trillion won in revenue. The company said it began shipping its next-generation HBM4 memory during the quarter and plans to lift 2026 capital spending into the high-40-trillion-won range, up from 30.2 trillion won in 2025, a signal that the AI-memory build-out is far from finished even as investors fret over its pace.
Three forces stacked on top of the earnings miss. The first was AI-spending fatigue: investors are increasingly questioning whether the breakneck pace of data-center capex can be sustained. According to Investing.com, Lee Min-hee of BNK Investment & Securities pointed to "concerns that tech firms will take a breather in infrastructure spending." The second was a report that Nvidia (NVDA) could provide roughly $250 billion in financial backing for OpenAI's data-center project, reviving worries about circular financing, where a chipmaker helps fund the customer that buys its chips.

The third force came from China. Per Investing.com, the blockbuster market debut of Chinese memory maker ChangXin Memory Technologies (CXMT), together with progress in China's domestic chipmaking equipment, reignited fears of oversupply in exactly the memory segments where SK Hynix and Samsung dominate. The Korea Exchange twice triggered a circuit breaker as the KOSPI fell past 8%, halting trading for 20 minutes in a second consecutive session.
The US-Listed Read-Through
Samsung and SK Hynix are not available to trade as fractional shares on Gotrade, so the cleanest read-through runs through their US-listed peers. In memory, Micron Technology (MU) is SK Hynix's closest listed comparison and fell 8.85%, moving on the same HBM-demand-versus-oversupply theme, while fellow storage name SanDisk dropped 14.25%. Nvidia sits at the center of the story as both the largest HBM customer and the source of the $250 billion financing catalyst. On the manufacturing side, Taiwan Semiconductor (TSM), the world's largest foundry, remains the barometer for sentiment on the global chip-production cycle.
For investors, the episode is a reminder that semiconductors trade as one interconnected ecosystem, from Asian memory suppliers to US-listed designers and foundries. A doubt about the durability of AI spending in Seoul travels the whole chain. Understanding that linkage helps put a sharp single-day move in context, without treating one session's selloff as the last word on the sector's direction.
