Quick Summary

Friday saw a significant sell-off in tech stocks on Wall Street, with the S&P 500 down 1.9% and the Nasdaq composite falling 3.1%, heading towards their worst performance since June. This downturn was driven by concerns over high valuations tied to artificial intelligence investments, particularly after Intel’s disappointing profit forecast and Amazon's report of significant cash burn from AI investments. Canada's S&P/TSX composite index also declined about 2.3% midday.

Story summary

On October 28, Google's parent company Alphabet reported weaker-than-expected earnings for the third quarter, leading to a significant stock price drop starting that evening. By October 29, Alphabet’s stock plunged by as much as 15.8%, erasing over $500 billion in market value in just one day—its worst performance since going public more than two decades ago. This sharp decline was driven by concerns over the company's massive spending on artificial intelligence (AI) and whether such investments will yield sufficient returns. The drop also affected broader markets, with the tech-heavy Nasdaq losing nearly 2%, dragging down other major indices like the S&P 500 as well. This trend continued into October 30, when another significant market value loss of approximately $1 trillion from the Nasdaq was reported due to a deepening sell-off in technology stocks following more disappointing earnings reports and heightened investor scrutiny over AI investments' profitability.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
