$NVIDIA(NVDA)$earnings are in the rearview. Where does the AI capital cycle flow next? The diffusion map is clear — money is rotating down the stack across 5 stages. The alpha window is different at each one. Stage 1: GPU & CPU $NVIDIA(NVDA)$ + $Advanced Micro Devices(AMD)$. Where the AI wave started, where capital concentrated first. Valuations are high. Most retail investors entered late here. Stage 2: Memory (actively running — highest alpha right now) $Micron Technology(MU)$ HBM demand surge, severe supply-demand imbalance, price and volume both rising.

Unlike Micron's HBM scarcity thesis, AMD must still prove its AI compute market share gains with hard data. In this AI infrastructure rotation, will AMD deliver its own 'Micron moment'?
