Microsoft Stock Soars 32.8% on Strong Cloud Growth in Q4 2026

Microsoft (MSFT) stock surged 32.8% between July 2 and October 2, 2026, significantly outperforming the S&P 500's 3.5% gain. The rally began after the company's fiscal Q4 2026 earnings report on July 29, which eased earlier investor concerns about AI disrupting software companies. The report highlighted strong growth in cloud computing and office software, with Azure and other cloud services revenue rising 43% in the quarter, while total revenue grew 18%. Microsoft also reported over 30 million paid seats for Microsoft 365 Copilot, with net seat additions doubling from the previous quarter.

The positive results led to a massive market value increase of about $450 billion on July 30, marking the largest one-day gain by any company, according to The Motley Fool. The Intelligent Cloud segment, which includes Azure, contributed $39.3 billion to the company's $90 billion in Q4 revenue, growing 32% in the quarter. Microsoft's commercial backlog, representing revenue under contract, surged 84% to $678 billion, or 25% excluding OpenAI.

Despite the growth, Microsoft stock trades at a premium, with a price-to-earnings ratio of 28.7, compared to 21.5 for the S&P 500. The company continues to invest heavily in capacity, spending $41 billion on capital expenditures in fiscal Q4 2026. Management expects capital expenditures to rise further in fiscal 2027 but anticipates only a slight decline in operating margins. Over the past year, free cash flow equaled 50.1% of net income, with potential for improvement in fiscal 2027.

The article concludes by advising investors to consider a diversified approach, such as the Trefis High Quality (HQ) Portfolio, which has returned 105% since its inception, rather than betting on a single stock like Microsoft.
