Microsoft Stock Soars 15% on AI Cloud Boom

Microsoft's stock saw a substantial 15% single-day jump after the release of its fiscal year 2026 earnings report, which concluded on June 30, 2026. Despite this significant rally, the stock remains down for the year but has recovered 27% from its 52-week low on June 25, 2026, indicating strong recent momentum.

Investors have been closely watching Microsoft's capital expenditures related to artificial intelligence. The latest results offer positive signs, with Microsoft Azure revenue increasing 41% year-over-year to cross $100 billion annually. Microsoft Cloud revenue also rose 27% year-over-year, exceeding $214 billion.

The company's cloud backlog reached $678 billion, showing continued high demand, though a portion is linked to OpenAI. Importantly, the backlog grew 25% year-over-year even when excluding OpenAI figures. This suggests broader AI-driven demand for Microsoft's cloud services.

Conversely, Microsoft's consumer-facing businesses have shown weakness. In the most recent quarter, the 'more personal computing' segment's revenue decreased by 4% year-over-year. Xbox hardware sales fell 13%, and Windows OEM/devices revenue declined by 7%. These segments, while less critical for growth than cloud and AI, are areas to monitor.

Investors considering a purchase should exercise caution. Previous rallies this year, such as a 14% rise in April and an 11% rise in late May to early June 2026, were followed by pullbacks. While past performance is not indicative of future results, these instances suggest that current rallies may not be sustained indefinitely.
