On October 13, Micron Technology fell 5.21% in Regular Trading, trading at $933.0 per share, with turnover of $3.765 billion.

The move came as memory stocks weakened broadly after reports highlighted that China-based CXMT claimed a DRAM technology breakthrough and continued capacity expansion, raising concerns that future supply competition could intensify price volatility across the memory market.

Recent reports said CXMT is pushing a new 4F2 data-center DRAM design targeted for launch by year-end, while market commentary also noted that expanding Chinese DRAM capacity could disrupt the supply landscape even as high-bandwidth memory demand remains strong. In the same session, SK hynix fell more sharply, reinforcing that the pressure was sector-wide rather than company-specific. Separately, Micron had disclosed a $35.16 billion share repurchase plan, but that capital return announcement did not offset the immediate industry-driven selling pressure.
