Microsoft stock jumps 15% as strong quarterly results and forecasts ease AI spending concerns; S&P 500 climbs sharply.

Microsoft's stock jumped 15% after the company reported strong quarterly results and provided forecasts that exceeded expectations, easing investor concerns about AI spending. The tech giant's forecast for current-quarter sales and cloud growth was particularly encouraging, leading to a significant rise in its share price.

The S&P 500 also saw a sharp increase, reflecting a broader rally in the tech sector. U.S. stocks gained on Thursday as investors reacted positively to Microsoft's performance, which was seen as a bellwether for the industry. The market was further buoyed by fresh GDP and inflation data released a day after the Federal Reserve's rate decision, which had left rates unchanged.²

Microsoft's forecast indicated that it expects to maintain strong cash generation through its fiscal 2027, which just began. This outlook, combined with capital expenditure below estimates, has reassured investors that the company can navigate the challenges posed by rising interest rates and ongoing investments in AI technology. The sentiment in the market suggests that while spending on AI remains a concern, companies like Microsoft view it as a competitive necessity, potentially leading to continued investment despite economic pressures.

The concern is no longer just how much these companies are spending - it's that higher rates may not deter them from spending more, as they see the AI buildout as essential for future growth.
