Microsoft (MSFT) is heading for its worst monthly performance since the dot-com bubble burst in 2000, having shed more than $570 billion in market value during June alone.
The scale of the decline marks a stark reversal for the software giant, which has long been viewed as a defensive anchor in the technology sector.
The sell-off reflects growing investor impatience with the company's aggressive spending on artificial intelligence infrastructure.
Despite the broader AI boom lifting many peers, Microsoft's valuation is coming under pressure as traders question the near-term return on these massive capital investments.
The market is effectively repricing the risk that the company's burn rate may outpace revenue growth in the short term.
This development aligns with a broader pattern of volatility in big tech.
