US Stock Market Report — 2026-05-28
Big Picture
U.S. equity markets closed mixed on Wednesday May 27 — the first trading session after the Memorial Day holiday — with the Dow Jones notching a fresh record while the S&P 500 and Nasdaq essentially flatlined. Tech stocks paused for breath after the previous session's semiconductor-fueled surge, and a drop in oil prices signaled easing geopolitical tensions around the U.S.-Iran nuclear talks. Markets are now looking ahead to Thursday's PCE inflation reading, the Fed's preferred gauge, which could shift rate-hike expectations.
Top Developments
1. Micron Joins the $1 Trillion Club
Micron Technology ($MU) surged 19% on Tuesday May 26, crossing $1 trillion in market capitalisation for the first time and becoming the 10th-largest U.S. company. UBS raised its price target to $1,625 from $535, implying 100%+ upside. The stock has gained more than 800% over the past 12 months and 200%+ in 2026 alone. The rally rippled through the memory-chip ecosystem: Seagate +4%, Western Digital +8%, VanEck Semiconductor ETF (SMH) hit a 52-week high.
2. U.S.-Iran Diplomatic Breakthrough Lifts Risk Appetite
President Trump said talks with Iran to end the conflict are "proceeding nicely," and a draft memorandum suggests Tehran would reopen the Strait of Hormuz. Brent crude dipped toward $96/bbl on the news while WTI held around $90. Oil had been the key inflation pressure throughout the Iran conflict; a resolution could ease energy-driven price pressures significantly.
3. Dow Hits Record; S&P 500 and Nasdaq Pause
The S&P 500 closed at 7,520.36 (+0.02%) and Nasdaq at 26,674.73 (+0.07%), both barely changed. The Dow Jones Industrial Average gained +0.36% (+182.60 pts) to settle at 50,644.28, a new record close. The VIX fell -4.23% to 16.29, reflecting elevated but declining volatility.
4. Q1 Earnings Season: 28%+ Profit Growth — Best Since Q4 2021
With most S&P 500 companies having reported, first-quarter earnings are running +28% year-over-year, the strongest growth rate since Q4 2021. This earnings strength is the fundamental driver behind the elevated index valuations and the year-to-date ~27.7% S&P 500 gain.
5. Analyst Calls: Nvidia Upgraded, Intel Downgraded
Rothschild & Co raised Nvidia's price target to $300 (~$40% upside), citing datacenter revenue acceleration to $300bn ARR with 92% YoY growth. HSBC upgraded Marvell Technology to Buy at $300. Meanwhile, Northland Capital downgraded Intel to Market Perform, arguing the 234% YTD gain has run too far given data-center spending headwinds.

Looking Ahead
Thursday's PCE inflation report is the marquee event. With oil prices having moderated on Iran de-escalation hopes, the Fed's preferred inflation gauge could show a meaningful decline — or might still surprise to the upside. Either way, traders are now pricing in an 11% chance of a July rate hike, up from near zero recently, so any hot PCE number could quickly reprice the rate path. Salesforce and Costco also report earnings Thursday.
