Motley Fool analysis indicates that while the S&P 500 index has risen over 10% year-to-date, Microsoft's stock price has surged 20% in the past month, primarily driven by its strong earnings performance. The report shows that Microsoft's cloud business revenue for Q4 FY2026 increased by 27% year-over-year, accounting for approximately two-thirds of total revenue; overall revenue and operating income both grew by 18% year-over-year. The analysis suggests that Microsoft's valuation is lower than the S&P 500, and with continuously improving fundamentals, it is poised to outperform the broader market in the future.
