Micron (MU) RSI Hits 90, Most Overbought in Nearly 30 Years, Echoing 1995 Warning

Micron Technology (MU) shares have surged into extremely overbought territory, with the relative strength index (RSI) reaching 90, according to Yahoo Finance AlphaSpace data. The last time the memory chip maker’s RSI was this elevated was on Sept. 1, 1995, when it touched 96—a level that preceded a monthslong sell-off into July 1996. The rally has been powered by surging demand for memory chips from AI data centers, as hyperscalers like Amazon build infrastructure. HSBC analyst Ricky Seo noted “booming general server demand” is driving a stronger and longer memory cycle. Micron crossed the $1 trillion market capitalization milestone on May 26, 2026, and now stands at $1.1 trillion, up 240% year-to-date. The extreme momentum reading suggests a corrective pullback may be imminent.
