On October 13, Micron Technology declined 3.03% overnight, trading at $958.3/share with turnover of $94.9111 million. The memory sector continued to adjust under triple pressure: post-holiday catch-up declines in Korean equities, the early termination of Samsung and SK Hynix's roughly $40 billion record buyback program, and ChangXin Technology's announced 4F² architecture breakthrough potentially giving it a two-year lead over Korean giants in cell architecture.

Despite fundamentals at historic highs, investors have begun pricing in supply-demand reversal risks from capacity expansion in 2027–2028. Foreign ownership of Samsung Electronics fell to 46.37%, a 17-year low, transmitting negative sentiment from Korean stocks to U.S. markets, with SanDisk and Micron collectively under pressure. Options data showed implied volatility at 50.59% with IV percentile of only 1.59%, indicating relatively inexpensive options pricing, while large trades reflected a cautiously bullish sentiment.
