Satya Nadella's Microsoft Stock Jumped 18% in a Week After Azure's Annual Revenue Topped $100 Billion for the First Time. Is It Still a Buy?

Microsoft's stock surged 18% following strong Q4 fiscal 2026 earnings, driven by Azure's milestone achievement of $100 billion in annual revenue and 43% growth. The company reported 18% revenue growth to $90 billion and 31% net income growth, with Microsoft 365 Copilot surpassing 30 million paid seats. Despite trading at a higher forward P/E of 25x (up from 19x pre-earnings), analysts expect 15-16% annual earnings growth over the next three to five years, making the stock still attractive for long-term investors.
