Microsoft shares closed at $516.17 on September 25, 2026, rebounding sharply from June lows near $350 amid accelerating Azure growth of 43% year-over-year in the fiscal fourth quarter and sustained AI demand through Copilot adoption. Traders are focused on the October 28 earnings release for fiscal first-quarter 2027 results, which will provide updated guidance on cloud margins, capital expenditure trends, and revenue trajectory following the October 7 Windows and Surface event highlighting local AI capabilities. At a trailing P/E of 28.8 and forward multiple near 26, the stock reflects market-implied expectations for continued double-digit earnings expansion, though broader tech sentiment and macroeconomic factors such as Treasury yields could influence closing levels by month-end.
