Memory Supercycle: Why MU & SNDK Are Set for a Grand Finale

The important second-order effect is that this is no longer just an AI compute story; it is turning into a memory-capacity bottleneck story, which tends to be more explosive but also more fragile. When one sub-segment captures almost all incremental scarcity rent, upstream suppliers, equipment vendors, and even packaging/test capacity can see price dislocations before end-demand fully normalizes. That typically creates a two-phase trade: first, multiple expansion on scarcity; second, margin compression once supply response and customer qualification catch up.

SNDK appears to be the cleaner expression of the momentum/scarcity trade than NVDA here, because the market is rewarding the component that is most directly constrained and hardest to substitute in the near term. NVDA still benefits indirectly if memory supply supports larger model training runs and higher accelerator utilization, but the marginal upside is likely less convex because it is already the consensus AI proxy. The more subtle winner set is likely adjacent infrastructure names with pricing power in advanced packaging, HBM-adjacent assembly, and test equipment; these often lag the headline names even though they participate in the capex supercycle.

The risk is that the market is extrapolating peak shortage economics too far out on the curve. Memory cycles usually reverse faster than narrative cycles because foundry and capex responses arrive with a lag, while end customers can temporarily de-rate inventory if hyperscaler budgets pause for even one quarter. In the next 1-3 months, the main catalyst is earnings guidance and any evidence of order pushouts; over 6-12 months, the key question is whether AI capex remains linear or becomes more disciplined as ROI scrutiny increases.

The contrarian miss is that the biggest blow-off in this trade may not be the current leaders, but the second-order beneficiaries that have not yet fully repriced. If the market is already crowded long SNDK, the cleaner risk/reward may be a relative-value expression versus lower-beta AI winners or against names where AI sentiment is already embedded in valuation. The setup argues for respecting momentum but avoiding outright chase after vertical moves unless there is confirmation of continued ASP upside and no evidence of supply normalization.
