Shares of Micron Technology and SanDisk have entered overbought territory following a rally driven by artificial intelligence demand [1].
This surge reflects a tension between the rapid expansion of AI infrastructure and a constrained supply chain. Because memory chips are essential for AI processing, the resulting price spikes have created a valuation gap that some analysts believe is unsustainable.
Market activity peaked during the week of May 30, 2026, as both companies hit new highs [2]. The rally is fueled by a combination of booming demand for AI-capable memory and historic hardware backlogs that have kept supply tight [3].
Chart technician Carter Worth said SanDisk is the "most overbought stock ever" [4]. This assessment comes after a period of growth for the company. Reports on SanDisk's share price increase over the past 12 months vary, with figures ranging from 3,350% [5] to 4,405% [4].
Micron Technology has also seen gains during the same period. The company's share price increased by 571% over the past year [5].
Analysts said that while the fundamental demand for memory is real, the speed of the stock price ascent may outpace the actual delivery of hardware. The current market condition is characterized by extreme optimism, a state that often precedes a correction when supply finally catches up to demand [3].
“SanDisk is the "most overbought stock ever."”
The extreme valuation of these memory stocks indicates a high-speculation environment where investors are pricing in years of future AI growth today. If hardware backlogs clear faster than expected or if AI adoption slows, these stocks could face a sharp correction. The disparity in reported growth percentages for SanDisk further highlights the volatility and rapid price shifts currently defining the semiconductor sector.
