KOSPI Erases 2.3% Early Gain as SK Hynix Slides

The intraday reversal matters less than the concentration it exposes: a single chipmaker's move was enough to flip the benchmark from a solid gain to a loss, which says the index's direction is effectively a proxy for semiconductor sentiment. That leaves Korean equity risk tightly coupled to memory-cycle expectations, with little cushion from other sectors. Whether SK Hynix stabilizes or the weakness broadens beyond chips is the open question for anyone tracking Asia's tech-heavy benchmarks.
