Microsoft shares jumped about 15% on Thursday, the largest single-day move in the company recent history, after its cloud division grew at the fastest rate in four years.
That one stock did most of the work in dragging the American market back from Wednesday sell-off, and the rally built through the session. The Nasdaq Composite closed 2.8% higher at 25,122.18. The S&P 500 rose 1.7% to 7,437.64 and the Dow Jones Industrial Average added 613.92 points, or 1.2%, to 52,208.06. Microsoft recorded its largest single-day gain in market value on record.
Meta moved the other way, falling after a revenue forecast that disappointed. The two largest technology results of the week landed within minutes of each other and produced opposite outcomes.
What Microsoft actually delivered
Revenue reached $90.01 billion for the quarter ended 30 June, ahead of the roughly $87.62 billion expected. Azure, the cloud business, grew 43% in constant currency against about 40% forecast, and accelerated from 40% in the previous quarter.
Azure revenue passed $100 billion for the full fiscal year for the first time. Management guided to 45% growth in the current quarter, above a consensus near 41%.
One detail did more for the share price than any of those. Capital spending for the quarter came in below what investors expected. In a week when the market has punished every sign of heavy artificial intelligence investment, spending less than feared while growing faster than forecast is close to the ideal combination.
Why one stock could lift the whole index
The size of the move in the indices relative to the number of companies involved is worth explaining.
The Nasdaq 100 and the S&P 500 are weighted by market value, so the largest companies contribute most to the index. Microsoft is among the two or three biggest, which means a 15% move in that one share can lift the whole index by a meaningful fraction of a percent regardless of what the other constituents do.
This is the concentration problem working in the favourable direction. On Wednesday the same structure pushed the Nasdaq Composite more than 10% below its record high. On Thursday it pulled the index back up.
Our earlier analysis of this concentration examined how it splits the indices apart on days when the megacaps and the rest of the market disagree.
The economic data helped, in an unusual way
Thursday morning brought two figures that would normally be read as unwelcome.
Second-quarter gross domestic product grew at an annual rate of 1.5%, below forecasts and slower than the 2.1% recorded in the first quarter. The Federal Reserve preferred inflation gauge showed prices 3.7% higher than a year earlier, with the core measure at 3.3%.
Equities rose anyway, because slower growth reduces the argument for higher interest rates. The core monthly inflation reading of 0.1% came in below the 0.2% expected, which supported the same conclusion. Weak growth data becoming good news for shares is a reliable feature of markets when the dominant question is the direction of policy rather than the direction of profits. Our breakdown of both releases covers what was underneath them.
The bond market has not joined in
There is a caution attached to Thursday rebound that equity prices are not reflecting.
The thirty-year Treasury yield closed above 5.2% on Wednesday, its highest level since 2007, and that repricing has not reversed. Long-term borrowing costs at a nineteen-year high are the market saying it expects inflation to persist, which is the opposite of what a rally built on hopes of rate cuts assumes.
One of those two markets is wrong. Equities are pricing an easing cycle that long-dated bonds are not.
What comes next
- Apple and Amazon report after the close on Thursday, completing the largest week of technology results in the calendar.
- Whether the semiconductor decline that ran for four consecutive sessions this week resumes, since it has been the main drag on the Nasdaq.
- Whether long-term Treasury yields ease from their nineteen-year high, which would validate the equity rally.
- Meta guidance, which set a third-quarter revenue range whose lower end sits below what analysts expected.
Outlook
Thursday was a rebound driven by one exceptional company result rather than a broad improvement in conditions.
Microsoft demonstrated the thing the market has been demanding all month: that heavy artificial intelligence spending produces revenue quickly enough to justify itself. Azure accelerating to 43% while capital spending came in lighter than feared is a direct answer to the question every technology company has been asked this earnings season.
Whether that answer generalises is the open question. Microsoft sells cloud capacity, so its returns are visible in a reported segment. Most of its peers cannot show the same thing, which is why one company result lifted the index while another dragged.
About the data: Microsoft figures are from its fiscal fourth-quarter 2026 results for the quarter ended 30 June 2026, including revenue, Azure growth in constant currency, full-year Azure revenue and management guidance for the current quarter. Analyst expectations are consensus estimates compiled before the release. Share price and index moves described are intraday on 30 July 2026 while US markets were open and will differ from closing values. Gross domestic product is the advance estimate for the second quarter published 30 July 2026 and is subject to revision. Personal consumption expenditures price index figures are from the June 2026 release published the same day. The thirty-year Treasury yield is a closing value for 29 July 2026.
