Sandisk Is Up 613% in 2026 and Micron Isn't Far Behind. Which AI Memory Stock Has More Room to Run?

Both Sandisk and Micron have surged in 2026 due to AI data center memory demand, with Sandisk up 613% and Micron up 272%. However, Sandisk's gains are heavily driven by pricing rather than volume, raising concerns about sustainability. Micron appears better positioned with diversified memory products (NAND and DRAM), a custom high-bandwidth memory partnership with Nvidia, and stronger long-term growth potential.

Nvidia Is About 4% From Becoming the First $6 Trillion Company. History Says the Milestone Itself Tells You Little.

Nvidia is approaching a $6 trillion market cap milestone, but historical analysis of past trillion-dollar milestones shows the milestone itself is not predictive of future stock performance. What matters most is earnings growth relative to valuation multiples. Nvidia's strong earnings growth (120% EPS increase last quarter) and relatively low P/E ratio of 15x suggest the stock could continue climbing if earnings growth outpaces valuation compression.

Nvidia Hits a New All-Time High. Is the AI Stock a Buy?

Nvidia reached a new all-time high of $243.37 per share, driven by positive macro conditions and strong AI sector momentum. Trading at a P/E ratio of 30, the stock appears undervalued compared to peers like AMD (166 P/E) and Intel (103 P/E), with Wall Street expecting 67% revenue growth to $687 billion in fiscal 2028. While the law of large numbers may eventually constrain growth and competition from AMD, Intel, and custom chips from Amazon and Google pose risks, analysts view Nvidia as well-positioned to capitalize on AI growth and recommend it as a strong buy.

The company expects non-handset revenue to grow over 60% in fiscal 2027 and projects a $200 billion CPU market opportunity by fiscal 2029, yet trades at a modest 23 P/E ratio that undervalues its growth potential.

Here's Why SpaceX's AI Infrastructure in Space "Moonshot" Won't Uproot Neocloud Companies

SpaceX launched a test satellite with Google's TPUs to explore orbital data centers, but satellite-based data centers will cost 2.5-3x more than Earth-based facilities. Tech giants need computing power immediately and are investing heavily in neocloud companies like Nebius and Iren, which have available megawatt capacity and scaling pipelines. Orbital data centers are unlikely to replace terrestrial data centers in the near term.

Not Nvidia. Not Micron. If I Could Buy and Hold Only 1 Artificial Intelligence (AI) Chip Stock Through 2030, It Would be This One.

While Nvidia and Micron dominate AI chip headlines, Taiwan Semiconductor Manufacturing (TSMC) is positioned as the superior long-term AI infrastructure play. TSMC controls ~73% of the foundry market and ~90% of advanced-node capacity, making it the critical bottleneck in AI chip production. With AI-accelerator revenue expected to compound at 50%+ through 2030, strong financial growth (36% YoY revenue growth in 2025), expanding margins, and a forward P/E of 28, TSMC offers better value than chip designers while maintaining a durable competitive moat.
