Micron Technology has become the top-performing stock in the S&P 500 over the last five years, with total returns ranging from approximately 1,114% to 1,315%. In comparison, the S&P 500 index returned about 82% during the same period.
As of early September 2026, the company's market capitalization is approximately $1.15 trillion, with shares trading around $1,017. The stock reached a 52-week high of $1,255. In 2025, Micron recorded a full-year return of 240%, followed by a year-to-date gain of 256% in 2026.
The growth is driven by the expansion of AI data centers, which increased demand for DRAM and high-bandwidth memory (HBM). These chips are used alongside GPUs for large language models and autonomous driving systems. This surge has increased Micron's revenue, profit, and pricing power.
Despite the rally, the stock's forward price-to-earnings ratio remains in the single digits to low teens. Market conditions for memory products are expected to stay tight beyond 2027. Potential risks include a slowdown in data center spending or increased capacity from competitors Samsung and SK Hynix.
