Microsoft shares closed at $516.17 on September 25 after surging more than 3.6% on the Copilot platform overhaul, which added code-generation tools, deeper Office integration, and an autonomous agent feature. The move follows Stifel’s upgrade to Buy and a $575 price target, with consensus targets now clustered near $576 amid expectations for Azure growth of 44-45% in the fiscal first quarter. Traders are also monitoring Treasury yields, geopolitical developments affecting energy prices, and the absence of immediate earnings catalysts before the October 28 report. The recent momentum has lifted the stock to its highest close in nearly 11 months, with heavy AI-related capex continuing to shape margin and revenue outlooks.
