Microsoft shares are on course for their most prolonged losing streak in more than a decade, having declined for eight consecutive days. This continuous slide has erased nearly $350 billion from the company's market value, with the stock dropping 8.6% over this period. The negative sentiment from investors stems from growing concerns over Microsoft's substantial expenditures on artificial intelligence infrastructure. This apprehension has overshadowed recent positive news, such as the better-than-expected growth in its Azure cloud computing division, leading to a broad sell-off in AI-related stocks.
