S&P 500 futures rise as Micron surges after earnings; Wall Street awaits key inflation reading: Live updates

U.S. stock futures rose, with Nasdaq 100 futures up 1.9% and S&P 500 futures up 0.5%, as Micron surged nearly 15% after a strong fiscal Q3 beat and upbeat current-quarter revenue guidance of $50 billion versus $43.58 billion expected. Qualcomm also jumped 14% on raised long-term non-handset revenue guidance, lifting other chip stocks ahead of Thursday's key May PCE inflation report, where headline inflation is expected to rise 0.5% m/m and 4.1% y/y.

Analysis

The tape is signaling a classic “good breadth / bad leadership” transition: strong AI memory and semicap guidance is pulling the entire complex higher, but the incremental edge is not in chasing the high-beta futures pop. The more durable read-through is that capex expectations for AI infrastructure are still being revised up, which supports the equipment and storage supply chain for the next 2-3 quarters; the second-order winner is less the headline winner and more the companies with operating leverage to tighter supply and higher utilization.

What matters most is not just that memory demand is improving, but that management is now willing to talk in terms of multi-year non-handset and server-related visibility. That tends to reset sentiment across the semiconductor ecosystem, but it also raises the bar: if memory pricing continues to inflect, the market will quickly rotate from “earnings relief” to “peak cycle” questions. The names most exposed are the ones with the highest beta to capex cuts if the macro print disappoints tomorrow; equipment stocks can outperform on the way up but de-rate just as fast if PCE forces rate-cut expectations out.

The inflation setup is the real overhang. A hotter-than-expected core PCE would pressure duration-sensitive tech and likely flatten the futures bid, even if the semiconductor group stays relatively resilient on company-specific momentum. Conversely, a benign print could ignite a further squeeze into semis, but the more crowded trade is now the index-level beta chase, not the individual fundamentals.

Contrarian take: the market may be underestimating how much of the chip rally is actually a function of sentiment repair rather than immediate earnings power in the broader complex. If the rotation out of mega-cap tech broadens into cyclicals and financials, semis can still work, but leadership should become more selective—quality exposure to cash-generative names with visible AI content, not an indiscriminate long basket.

Key Decisions for Investors

• Go long MU vs. short XLK for the next 2-6 weeks: MU has the cleanest earnings/guidance inflection, while the index hedge reduces exposure to a hotter PCE print that could hit duration-heavy tech.
• Buy call spreads in KLAC or LRCX into the next 1-2 months: equipment names should lag MU on day one but catch a stronger second-order bid if fabs convert memory optimism into capex revisions; use spreads to cap downside if macro data disappoints.
• Fade the sympathy rally in WDC/SNDK on strength with tight stops over 5-10 trading days: these are more sensitive to mean reversion if the market starts pricing peak-cycle memory rather than early-cycle recovery.
• Pair long QCOM vs. short AMAT for 1-3 months if you want semis exposure with less capex risk: QCOM’s re-rating is supported by long-dated diversification, while AMAT is more vulnerable if PCE keeps real yields elevated.
• If core PCE prints hot, sell strength in semiconductor ETFs intraday and rotate into industrial/financial beneficiaries; if it prints cool, use any pullback to add to MU/QCOM rather than chasing broad Nasdaq beta.
