Can Micron Stop the AI Selloff After Korea’s Leverage Flush?

South Korea's leverage flush hammered memory chipmakers, with Samsung and SK Hynix both dropping over 12% in a selloff that rippled into U.S. markets and hit Micron (MU). The tech rout originated from forced deleveraging in Korean markets, pressuring the semiconductor names most exposed to AI memory demand.

The question now centers on whether this is a transitory liquidity event or the beginning of a broader correction in the AI chip trade. Micron's upcoming earnings will serve as a critical litmus test for the health of AI infrastructure spending and HBM (high-bandwidth memory) demand that has fueled the rally in memory stocks.

The Korean selloff offers a stress test for sentiment around AI chip makers. Memory stocks had surged on expectations that generative AI buildouts would drive sustained demand for advanced memory products. A sharp pullback in Samsung and SK Hynix—key suppliers alongside Micron—raises questions about whether valuations had stretched too far ahead of fundamentals or if margin call dynamics temporarily dislocated pricing.
