Wall St futures rise on AI optimism; investors optimistic on Mideast truce

U.S. stock futures rose as AI-led momentum and optimism over U.S.-Iran talks kept risk sentiment firm, with the S&P 500 and Nasdaq coming off record highs. Micron topped a $1 trillion market cap and gained 4.6% premarket, while peers Sandisk, Western Digital and Seagate rose more than 1.3%; however, Zscaler fell 21.5% on weak Q4 revenue guidance and GlobalFoundries dropped 6.6% on a reported block sale. Markets now await Thursday’s PCE inflation data, which could refine expectations for Fed policy and the rest-of-year rates outlook.

Analysis

The market is rewarding a narrow but powerful combination: AI capex optimism and still-benign earnings revisions. Memory is the cleaner second-order beneficiary than the headline AI software leaders because every incremental inference/training dollar still needs bandwidth and storage; that supports SNDK/WDC/STX even if the near-term enterprise demand backdrop is mixed. The more interesting signal is that the rally is broadening beyond “AI story stocks” into the component chain, which usually happens when investors start pricing a longer capex cycle rather than a one-quarter backlog pop.

GS’s higher year-end target matters less as a price call than as a positioning tell: systematic and macro funds will be pressured to chase equities higher while real-rate sensitivity remains constrained by still-elevated yields. That said, the setup is fragile into the PCE print; a sticky inflation surprise would likely hit the most duration-sensitive parts of the tape first, especially high-multiple growth and the more levered semiconductor suppliers. In contrast, a benign print could extend the current squeeze for several sessions as dealers remain under-hedged after recent index highs.

The sharp ZS reaction suggests the market is becoming less forgiving of any guidance miss, which is important for the broader software complex. If security budget growth is decelerating while AI-linked infrastructure spend remains hot, capital is likely to rotate from application-layer cyber and SaaS into picks-and-shovels hardware exposure over the next 1-3 months. GFS is a separate but related negative: block-sale overhang can cap rallies in any name where sponsor liquidity is the primary story, especially when public-market supply is increasing into a momentum tape.

Key Decisions for Investors

• Long SNDK / WDC / STX as a basket for 2-6 weeks; use any post-PCE dip to add, targeting 8-12% upside if AI infrastructure spend breadth keeps expanding, with a tight 4-5% stop if yields spike and semis de-rate.
• Short ZS into strength for 1-4 weeks or buy downside via put spreads; risk/reward favors follow-through on guidance misses because the stock can re-rate another 10-15% lower if the market decides billings growth is normalizing.
• Pair long SOXX or a memory-heavy basket vs short IGV/cyber software for 1-3 months; thesis is capital rotation toward infrastructure beneficiaries, with upside if PCE is benign and AI capex optimism persists.
• Avoid initiating fresh long GFS until the block-sale supply clears; if already long, consider reducing to a trading position and using a 1-2 month covered-call overlay to offset expected overhang.
• Use the PCE print as the macro trigger: add cyclicals/semis on a soft inflation surprise, but fade beta rallies if 10Y yields break higher as that would likely compress the multiple expansion driving the current tape.
