Microsoft's record $450B gain powers Nasdaq to 2.8% jump
Microsoft added $450 billion in market value in a single session, the largest one-day wealth creation in stock market history.
The Nasdaq Composite surged 2.78% on July 30 as Microsoft Corp. posted its biggest single-day gain since October 2008, adding a record $450 billion in market capitalization.
The rally followed Microsoft's fiscal fourth-quarter results, which showed Azure cloud revenue growth accelerating and beating analyst estimates, according to the company's earnings release. The performance marks a sharp contrast with Meta Platforms Inc., which fell 8% and extended a record losing streak as investors questioned the returns from its AI infrastructure spending.
The Philadelphia Semiconductor Index jumped 8%, snapping a five-session losing streak, as storage and optical communication stocks led the advance. The Roundhill storage exchange-traded fund surged 16%. SanDisk Corp. soared 25%, Micron Technology Inc. gained 18%, and SK Hynix Inc. rose 17%. Lumentum Holdings Inc. and Western Digital Corp. each added 15%, while Intel Corp. climbed 11%. The S&P 500 rose 1.67% and the Dow Jones Industrial Average added 1.19%.
The divergent moves between Microsoft and Meta show the widening gap in AI monetization across big tech. Microsoft's Azure-driven beat suggests enterprise cloud demand remains strong and that AI investments are translating into revenue growth. Meta's decline, by contrast, reflects investor skepticism about elevated capital expenditure without clear near-term returns.
The storage sector's broad rally signals a potential inflection point for the memory industry cycle. SanDisk and Micron, both heavily exposed to NAND flash and DRAM markets, posted the largest gains among semiconductor names. The Philadelphia Semiconductor Index's 8% rebound recouped a significant portion of the prior five sessions' losses, during which the index had fallen on concerns about export controls and demand softness. The Nasdaq's 2.78% advance marked its best day since June.
Technology and semiconductor sectors led the rally, while defensive sectors lagged as investors rotated back into growth names. Microsoft's single-session market cap increase of $450 billion exceeds the entire market value of all but a handful of S&P 500 companies, showing the scale of the AI-driven divergence within the technology sector.
The session's outcome raises the stakes for upcoming earnings reports from other mega-cap technology companies, as investors look for evidence that AI infrastructure spending is generating measurable revenue growth. Microsoft's Azure results set a high bar for peers, with the cloud division's acceleration suggesting that enterprise adoption of AI workloads is gaining momentum. The storage sector's strength, driven by demand for memory chips used in AI data centers, points to a broader recovery in semiconductor end-markets that could extend through the second half of the year.
