Microsoft shares closed October 5, 2026, near $526 after rising more than 1.5% intraday on multiple analyst upgrades, including Melius Research lifting its rating to Buy with a $665 price target and Scotiabank raising its target to $615. Momentum stems from fiscal Q4 results showing Azure revenue growth of 43% and a commercial backlog expanding 84% to $678 billion, underscoring sustained enterprise AI demand. Traders are also monitoring the October 28 earnings release for updates on Azure constant-currency growth and Copilot monetization. Broader tech sector strength and expectations for continued high-teens revenue expansion support current pricing, though heavy capital spending on data centers remains a key variable in margin trajectories.
