If the Fed holds and rates fall, AI-related stocks should benefit, but AI sub-sector rotation is fast. An active global AI ETF can better capture that rotation than a static exposure.

He favors a newly listed US AI/neocloud ETF (AIY) as an Astra-effect beneficiary. Neoclouds have more upside if rates fall, while hyperclouds are safer, and the ETF should benefit from OpenAI's Astra momentum.

He says OpenAI's Astra effect is a strong AI hardware catalyst: better coding performance came from using more GPUs, results are stored in memory/NAND, hallucination rates fell, and frontier-model reliability improved. That should expand demand for GPUs, DRAM, and NAND and revive interest in AI hardware after the July correction; the PLUS Global HBM Semiconductor ETF (442580.KS) is his preferred vehicle, with SK hynix, Samsung Electronics, and Micron each about 25% and SanDisk 5%.
