Story summary

On October 29, Alphabet's stock price plummeted by as much as 15.8%, erasing more than $500 billion in market value within a single day, marking the company's worst-ever one-day drop since it began trading over two decades ago. The sharp decline was triggered by Google-parent Alphabet missing profit projections and increasing AI spending past $50 billion in the third quarter, causing concerns that such massive investments may not yield sufficient returns. This tech sell-off deepened on October 30, pushing Wall Street towards its worst day since June, with the S&P 500 tumbling 1.8% and the Nasdaq dropping sharply as well.
