Microsoft stock price plunged after hours, record high expenses and slowing growth in cloud business.

Microsoft's stock price has fallen significantly, with the company's expenses soaring to a historic high, while the growth in cloud business sales has slowed down. Investors are concerned that the company's artificial intelligence investments may require more time than expected to see returns. In the second quarter, capital expenditures reached $37.5 billion, a 66% increase from the same period last year, exceeding analysts' expectations of $36.2 billion. Adjusted for exchange rate fluctuations, revenue from the Azure cloud computing division grew by 38% in the quarter, barely meeting analysts' expectations. However, this growth rate has slowed down compared to the previous quarter. The company expects Azure sales to grow by 37% to 38% in the current quarter. Microsoft's stock price fell by approximately 7% in after-hours trading, closing at $481.63 during regular trading hours in New York.
