US stocks enter a holiday-shortened week with momentum on their side and one number that could test it. The S&P 500 closed Friday near 7,490, capping an eighth straight weekly gain — its longest winning streak since 2023 — while the Dow finished at a record high. The data that could end the run lands Thursday.

Markets are closed Monday, May 25, for Memorial Day. That leaves four trading sessions, Tuesday through Friday, and an economic calendar front-loaded with the releases that move interest-rate expectations.

The Main Event: April PCE Inflation

The week’s headline catalyst is the April Personal Consumption Expenditures price index, due Thursday, May 28, from the Bureau of Economic Analysis. PCE is the Federal Reserve’s preferred inflation gauge — the measure it weighs most heavily when it sets interest rates.

Recent readings have run hot. The March PCE report showed headline inflation running at 3.5% year-over-year, with core PCE — which strips out volatile food and energy prices — at 3.2%. The April Consumer Price Index later came in at 3.8%, and producer prices jumped 6% from a year earlier, the steepest annual increase since 2022.

Economists broadly expect Thursday’s print to stay elevated. The Fed has long held that “inflation at the rate of 2 percent” is most consistent with its mandate, and core PCE at 3.2% sits well above that target. A hot April number would reinforce the “higher for longer” stance and shape the debate over whether Chair Kevin Warsh’s Fed cuts rates at all this year — a timeline that markets and major banks have already pushed deep into 2027.

Earnings: A Tech-Heavy Slate

Earnings season is past its peak, but the week carries a dense run of enterprise-software and retail reports. The marquee name is Salesforce (CRM), which reports midweek and serves as a barometer for corporate software spending and AI-product adoption.

Other reports to watch:

  • Dell Technologies (DELL) — server demand and AI-infrastructure orders.
  • Snowflake (SNOW), Marvell Technology (MRVL), Zscaler (ZS) and HP (HPQ) — the data, chip and cybersecurity read-through.
  • Retail: AutoZone (AZO), Dollar Tree (DLTR), Gap (GAP), Kohl’s (KSS), Abercrombie & Fitch (ANF) and Dick’s Sporting Goods (DKS) — a fresh check on the health of the US consumer.

For a market whose record run leans heavily on a handful of mega-cap technology names, the enterprise-tech prints carry outsized weight. A soft forward guide from Salesforce or Dell would land harder than any headline earnings-per-share figure.

Other Data on the Calendar

Beyond PCE, two more releases matter. Tuesday brings the Conference Board’s May consumer confidence reading — an early gauge of whether higher energy prices are denting household sentiment. Thursday is double-booked: alongside the inflation report, the BEA publishes its second estimate of first-quarter GDP, and the government releases durable-goods orders and weekly jobless claims.

What to Watch

The setup is straightforward. Three of the four sessions are quiet; Thursday is not. An in-line or cooler PCE print would let the eight-week rally extend into June and revive talk of a rate cut later this year. A hotter number — anything that shows core inflation reaccelerating — would do the opposite, lifting Treasury yields and pressuring the rate-sensitive corners of the market.

Trading volume tends to be thin in the sessions after a long weekend, which can amplify the reaction to any surprise. The practical takeaway for the four-day week: the tape belongs to Thursday morning, and everything before it is positioning.
