Extended read

While Nvidia dominated the initial phase of the AI boom, the first half of 2026 has seen a decisive shift toward memory and storage providers. Sandisk, Micron, and Western Digital have outperformed the broader index as the industry realizes that high-performance compute requires equally high-performance data throughput. Micron's 225% surge reflects a massive expansion in revenue and margins, driven by the transition to HBM (High Bandwidth Memory). However, analysts caution that the 10x 'millionaire-maker' returns may be behind us, with projected returns of ~4x through 2028.
