An abbreviated four-day week — US markets were closed Monday for Memorial Day — somehow packed in one of the most earnings-dense stretches of the year. Snowflake’s $6 billion Amazon deal and blowout quarter set the tone for Thursday. Dell reported revenue of $43.8 billion, up 88% year-over-year, with AI server orders of $24.4 billion booked in a single quarter. Salesforce raised its full-year revenue guidance. Best Buy and Dollar Tree both surprised to the upside on the same morning. And sitting underneath all of it: the S&P 500 clinched its ninth consecutive positive week — its longest winning streak since 2023 — even as PCE inflation printed at a three-year high of 3.8% and US-Iran negotiators agreed on a 60-day ceasefire MOU that Trump had yet to sign. The market absorbed all of it and kept climbing.

📊 Market recap

US markets were closed on Monday for Memorial Day. The week’s four sessions did not waste a moment.

Tuesday opened with Micron as the centrepiece. Shares surged approximately 18-19%, pushing the memory chipmaker past $1 trillion in market capitalisation for the first time, after UBS analyst Timothy Arcuri more than tripled his price target on the stock from $535 to $1,625, citing AI’s structural transformation of the memory market and long-term supply agreements with partially fixed pricing, per CNBC. President Trump’s public praise of Micron’s US investment plans also contributed to the move, per Motley Fool. The broader chip complex rallied in sympathy. The S&P 500 gained roughly 0.6% to close near the 7,500s, while the Nasdaq jumped roughly 1.2% to 26,656 — both at fresh all-time highs, per CNBC. The Dow slipped modestly, down about 0.2%, as oil prices eased slightly on renewed Iran negotiation signals, per TheStreet.

Wednesday was quieter on the surface but loaded underneath. Salesforce reported record first-quarter fiscal 2027 results after Tuesday’s close — revenue of $11.1 billion, up 13% year-over-year, with non-GAAP EPS of $3.88, up 50% year-over-year — and raised its full-year revenue guidance midpoint to $45.9 billion-$46.2 billion, per the company’s SEC filing. The guidance raise was technically an upgrade from prior targets, though it came in slightly below what Wall Street had been hoping for, per CNBC and Yahoo Finance. Slack reported 3 million custom AI apps built in the quarter, up 8x sequentially. Markets moved sideways on Wednesday as attention shifted to two evening catalysts: Snowflake’s quarterly earnings and news out of Tehran. Snowflake reported after the close, and the reaction was immediate. Revenue of $1.39 billion, up 33% year-over-year, beat estimates of $1.32 billion, and the company simultaneously unveiled a five-year, $6 billion spending commitment to Amazon Web Services focused on AWS Graviton chips and AI GPU infrastructure, per CNBC. CEO Sridhar Ramaswamy called the quarter an “inflection point” for the company’s AI transformation.

Thursday was the week’s defining session. Snowflake surged approximately 35-38% on the open — its best single-day gain ever — dragging the broader software and cloud complex sharply higher, per TheStreet. Dell reported after Thursday’s close: revenue of $43.8 billion, up 88% year-over-year, and diluted EPS of $4.86, up 214%, both all-time records, with AI server revenue of $16.1 billion booked and a backlog of $51.3 billion, per the company’s earnings call transcript. Dell shares surged roughly 12% in after-hours trading on the report, per Benzinga. Simultaneously on Thursday morning, Best Buy posted first-quarter revenue of $8.9 billion, with comparable sales up 2% on strong demand for computers and mobile devices, while Dollar Tree reported adjusted EPS of $1.74, beating estimates of $1.55 by nearly 13%, per Bloomberg and TradingPedia. The retail pair surged roughly 18% and 19% respectively on the session, per Bloomberg. On the macro side, PCE inflation for April printed at 3.8% year-over-year — the highest reading in nearly three years — but the monthly core PCE gain of 0.2% came in softer than expected, giving the market a silver lining to hold onto, per the Bureau of Economic Analysis as cited by Reuters. Separately, US and Iranian negotiators reached agreement on a 60-day memorandum of understanding to extend the ceasefire and begin nuclear talks, though President Trump had not yet approved it, per Reuters. Oil dropped sharply on the MOU headlines, the S&P 500 added roughly 0.6% to close near 7,560s, and the Nasdaq rose about 0.9% to the 26,900s — both at record closes, per CNBC.

Friday completed the ninth consecutive positive week. Markets digested the prior day’s earnings and macro data. The S&P 500 and Nasdaq held near their record levels, with the week’s headline gains driven overwhelmingly by the software, AI infrastructure, and consumer discretionary sectors. The S&P 500’s nine-week winning streak is its longest since 2023, per reporting.
