The Nasdaq-100 jumped 3% in a broad rally led by Microsoft and semiconductor stocks, according to Seeking Alpha. The advance marked one of the index's largest single-day moves in recent months, with gains concentrated in the technology sector. The rally came days after Microsoft reported record cloud revenue that beat analyst estimates.
Why it matters
That breadth matters because it suggests the buying is about sector fundamentals rather than a narrow bet on one part of the tech trade. Microsoft's strong cloud results last week gave investors a reason to believe AI infrastructure spending is translating to revenue, which helps both the software companies building the models and the semiconductor firms supplying the chips.
How this compares
Technology stocks had been under pressure in recent sessions as investors rotated toward other sectors ahead of a packed week of earnings and the Federal Reserve's policy decision. Microsoft shares surged on July 30 after the company reported quarterly results that beat estimates on record cloud revenue, crossing a revenue milestone as investors scrutinised returns on AI infrastructure investments. The Nasdaq had extended a chip sell-off on July 28 as investors positioned ahead of major technology earnings and the Fed announcement.
What to watch
The rally sets a stronger backdrop for the remaining technology earnings reports due this week. Investors will continue to parse results for evidence that AI spending is driving revenue growth rather than just costs, with semiconductor companies particularly in focus given their role in the infrastructure buildout.
