Micron Emerges as "Clear Winner" in AI Memory Stock Debate
- Sandisk stock has seen a rise of over 520% in 2026, making it the top-performing S&P 500 stock, while Micron has increased by approximately 225%, ranking fourth.
- Investor Keithen Drury from The Motley Fool identifies Micron as the stronger long-term investment due to its diversified business in both DRAM and NAND memory, and its proactive approach to building new production facilities.
Full Summary — powered by AI
The year 2026 has been exceptional for memory-chip stocks, driven by surging demand for artificial intelligence (AI) infrastructure. Both Micron (NASDAQ: MU) and Sandisk (NASDAQ: SNDK) have experienced significant gains. Sandisk’s stock has climbed more than 520% this year, securing its position as the best-performing S&P 500 stock, while Micron’s stock has risen around 225%, placing it fourth.
The robust performance of these companies is attributed to the AI-driven demand for memory, which has outpaced current supply, leading to a sharp increase in chip prices. Both companies are currently unable to meet the high demand. New manufacturing facilities are under construction, but significant production from Micron’s new sites is not expected until mid-2027, with Sandisk’s additional capacity coming online even later. This delay could sustain the current supply shortage.
However, the memory market has historically been cyclical, and there is a potential risk of prices falling sharply once new factories begin full-scale production. Top investor Keithen Drury, contributing to The Motley Fool, has compared the two companies and concluded that Micron is the “clear winner” for long-term investment. Drury highlights a key difference: Micron produces both DRAM (used for fast data access in computing) and NAND (used for long-term data storage), while Sandisk primarily focuses on NAND. Micron’s diversified business provides an advantage, allowing it to benefit from strong pricing in either segment. Additionally, Micron was proactive in constructing new production facilities, whereas Sandisk only recently began similar initiatives.
In terms of valuation, Micron trades at approximately 6 times its fiscal 2027 earnings estimates, while Sandisk is slightly more expensive at nearly 7 times forward earnings. Both companies are considered to have attractive valuations, reflecting investor concerns about potential future declines in memory prices. Micron’s upcoming results, expected on September 30, are projected by Wall Street analysts to show around 349% revenue growth. Micron has consistently exceeded revenue forecasts, demonstrating the difficulty in predicting earnings amid rapidly rising memory chip prices.
