5 AI Stock Picks for May 15, 2026

  1. WDC — Western Digital [Top Performer]
    The surge in demand for memory and storage solutions, highlighted by Cerebras' IPO and the AI chip boom, directly drives Western Digital's NAND and HDD shipments. Western Digital maintains a durable moat through vertical integration in NAND flash and HDD manufacturing, which enables cost leadership and supply chain control. The stock's 1-year return of +864.29% reflects a structural re-rating, and continued AI infrastructure buildout supports further earnings growth.
    Key risk: A sharp correction in NAND pricing or a major supply chain disruption could compress Western Digital's margins.
  2. AMD — Advanced Micro Devices [Top Performer]
    Nvidia competitor Cerebras made headlines with its IPO, highlighting surging demand for AI chips that directly benefits AMD's data center and AI GPU product lines. AMD's MI300 accelerator platform is ramping in hyperscale data centers, and the company posted 237% EPS growth with a PEG ratio of 0.62. The 1-year return of +261.95% confirms strong execution, and the combination of product cycle momentum and a PEG well below 1.0 supports further upside.
    Key risk: A delay or underperformance in MI300 accelerator adoption by major cloud providers could slow AMD's earnings momentum.
  3. FIS — Fidelity National Information Services [Contrarian Value]
    Yields surged to a one-year high, which pressures rate-sensitive financials but also creates opportunities for payment processors like FIS to benefit from higher transaction volumes and interest income. FIS owns the dominant banking core processing platform, serving over 20,000 financial institutions and generating $3,527M in free cash flow with a 3.7% dividend yield. The P/E ratio of 8.1x and PEG of 0.64 indicate the stock is priced for pessimism, but stable recurring revenue and improving FCF growth support a re-rating as macro fears subside.
    Key risk: A prolonged downturn in bank IT spending or a disruptive new fintech entrant could erode FIS's core processing revenue.
