Micron Is Up 698% in a Year. These 3 Stocks Under $15 Ride the Same AI Memory Wave Before Wall Street Notices

"Micron Technology has become the biggest beneficiary of the AI economy’s memory demand, with hyperscalers scrambling for HBM, DRAM, and NAND capacity to feed AI training clusters. The stock has run 124.41% year to date and 698.01% over the past year. With Micron now changing hands near $640.20, retail investors hunting exposure to the same data-explosion tailwind are looking down the supply chain for cheaper, leveraged plays."

"POET designs photonics-based optical engines and interposers used to move data between GPUs and memory inside AI servers, the exact bottleneck Micron's HBM stacks are trying to relieve. Shares closed at $9.21 after a 29.54% single-day move, leaving the stock up 45.5% year to date and accessible to small accounts. Q4 2025 revenue jumped 1,075.3% year over year to $341,202, and CEO Suresh Venkatesan said the company expects to "ship more than 30,000 optical engines this year" with $430 million in cash on hand."

"On April 27, 2026, POET disclosed that Marvell had cancelled all Celestial AI purchase orders citing alleged confidentiality breaches, sending shares down roughly 30% premarket. POET still has a strong cash position and a separate $5 million production order for its Infinity engines, which keeps the AI optics thesis intact for risk-tolerant investors."

Micron Technology has gained sharply as hyperscalers seek HBM, DRAM, and NAND capacity for AI training systems. Shares near $640.20 reflect strong demand for memory used in AI infrastructure. Investors looking for cheaper exposure are considering supply-chain companies tied to the same data and connectivity tailwind. POET provides photonics-based optical engines and interposers that move data between GPUs and memory inside AI servers. The company reported a large year-over-year revenue increase in Q4 2025, held substantial cash, and expected to ship more than 30,000 optical engines in the year. POET later disclosed that Marvell cancelled Celestial AI purchase orders due to alleged confidentiality breaches, but it still reported a separate production order for Infinity engines. Pixelworks is also mentioned as a technology licensing company anchored by TrueCut Mo.
