Microsoft shares closed at a record $543.45 on October 13 after a four-month rally that added roughly $1.4 trillion in market value since the June low, fueled by accelerating Azure revenue growth of 43% year-over-year in fiscal Q4 and strong AI demand. The company’s introduction of its Maia 300 custom AI chip, expected to improve efficiency versus third-party GPUs, further supports sentiment by addressing capital-expenditure intensity. With the stock trading near $543–$544 intraday on October 14 and consensus price targets around $580–$590, trader focus centers on whether momentum sustains ahead of the October 28 earnings release and any immediate CPI or FOMC signals that could shift broader risk appetite.
