"Tech Giants' Stocks Plummet as Market Reacts to Disappointing Financial Reports and Fed's Powell Announcement"

AI-related companies lost $190 billion in stock market value following disappointing quarterly earnings results from Microsoft and Google owner Alphabet. While Microsoft's promise of AI services convinced investors, its stock still dropped, and Alphabet's parent company saw a 5.6 percent decrease after missing ad revenue expectations. The dropoff may indicate investor wariness of tech companies overpromising on AI without a clear path to monetization, leading to questions about whether Wall Street has hit peak AI and if a bubble is about to burst.
