Stock Market Today, May 28: Inflation Isn't Stopping This Stock Market Rally

The S&P 500 rose 0.58% to 7,563.63, the Nasdaq gained 0.91% to 26,917.47, and the Dow added 0.05% as markets recovered from early losses and closed near record highs despite hotter-than-expected April PCE inflation at 3.8% year over year. The inflation print and persistent energy-price pressure reinforce expectations that the Federal Reserve will keep rates unchanged for the rest of the year, though stocks were supported by hopes for a 60-day U.S.-Iran truce and WTI crude falling below $90 a barrel. Individual movers were strong: Snowflake jumped 36% on earnings and a $6 billion Amazon deal, Microsoft rose on AI optimism, while Salesforce and Photronics fell.

Analysis

The market is sending a clearer message than the headline inflation print: the binding constraint is no longer growth, it is discount-rate uncertainty. If rates stay pinned through year-end while inflation remains sticky, the equity tape can still levitate, but leadership should keep narrowing toward businesses with self-funding balance sheets and pricing power; that is structurally favorable for AI-linked platform winners and unfavorable for names where investors were underwriting an eventual multiple expansion from lower rates.

Snowflake’s reaction suggests the market is rewarding monetization proof over narrative. A large strategic customer commitment materially reduces perceived demand risk and should pull forward scrutiny of adjacent data-infrastructure vendors, where investors will now demand evidence of workload expansion rather than just AI adjacency. That creates a second-order negative for slower-moving software names that are already capital-intensity stories disguised as growth stories.

The biggest underappreciated risk is that a ceasefire-driven oil decline can briefly compress inflation expectations without meaningfully changing Fed policy if core services stays firm. In that setup, rate-sensitive cyclicals may not get the usual benefit, while energy equities can underperform even if the macro news looks “positive” for consumers. Conversely, if geopolitics flare again, the market could quickly reprice both oil and rate volatility, which would punish crowded duration-sensitive longs.

The contrarian read is that the rally is less about confidence in a soft landing and more about investors treating inflation as a tradable headline rather than a regime shift. That makes the current move fragile over a 1-3 month horizon: good earnings can offset the macro for now, but any disappointment in AI capex payback or enterprise spending could trigger rapid multiple compression, especially in names where expectations have reset too aggressively upward.

Key Decisions for Investors

• Long SNOW vs. short CRM for the next 4-8 weeks: SNOW has a cleaner reacceleration narrative and near-term estimate revision potential, while CRM faces a tougher setup if AI spending remains a margin overhang; target 15-20% relative outperformance, stop if CRM regains premium on margin guidance.
• Add to AMZN on pullbacks over the next 2-6 weeks: the deal flow reinforces AWS/AI monetization optionality without requiring multiple expansion; use risk defined via call spreads to capture upside while limiting exposure if the market rotates back to pure rate beneficiaries.
• Short PLAB outright or buy puts into any post-earnings bounce over the next 1-2 months: weak demand plus soft guidance usually leads to follow-through selling in equipment/consumables names; downside can extend another 10-15% before valuation support matters.
• Pair long NVDA / short a basket of low-quality software beneficiaries over 1-3 months: the market is increasingly separating true AI enablers from expensive AI storytellers; NVDA benefits if capex remains concentrated, while the short basket is vulnerable to margin scrutiny.
• Do not chase broad index longs at record levels until PCE and oil stabilize for at least 2-3 prints; if the Fed stays on hold but inflation fails to cool, multiple expansion is capped and upside becomes more stock-specific than index-driven.
