Micron vs. Sandisk: 1 Artificial Intelligence (AI) Memory Winner Is Down 20% and Clearly the Superior Buy Today

Both Micron and Sandisk memory chip stocks are down 20% from all-time highs but remain strong performers in 2026 due to AI-driven demand. While Sandisk has outperformed year-to-date, Micron is positioned as the superior long-term buy due to its diversified exposure to both NAND and DRAM memory markets, lower valuation (15% cheaper on forward P/E), and better resilience if one memory segment reaches capacity.
