Tech Stocks Plunge, Dragging Down Wall Street Amid AI Frenzy Concerns

The technology sector experienced a sharp downturn on Wall Street, with broad market indices suffering their worst day since June as concerns mounted over the rapid ascent of artificial intelligence (AI) stocks. The S&P 500 declined 1.8%, marking its third consecutive losing week. The Nasdaq composite, heavily weighted with tech companies, led the losses with a 2.9% drop, while the Dow Jones Industrial Average fell 1.1%, or 572 points.

This market correction follows a period of significant gains, which had brought the S&P 500 close to its all-time high. However, the rapid rise in AI-related stock valuations has led to worries about potential overvaluation. Investors are now transitioning from a phase of "hopes and dreams" to one demanding tangible profitability from these investments, according to market analysts.

Several prominent tech companies reported significant losses. Intel's stock plummeted 28.6%, its steepest decline since 1974, after issuing a profit forecast that fell short of expectations, despite reporting a stronger profit for the latest quarter than analysts had predicted. Amazon saw its stock fall 1.4% following weaker-than-expected quarterly profits and a substantial increase in cash expenditure, with $42.4 billion spent on property and equipment over the preceding 12 months, largely driven by AI technology investments.

Alphabet, the parent company of Google, had previously experienced a more than 12% drop, its worst day on record, after reporting increased cash burn due to AI investments. Nvidia, a key player in the AI boom, also contributed to the market's decline, with its stock falling 4.2%.

Outside of the tech sector, other companies showed more resilience. ExxonMobil and Chevron saw gains of 2.2% and 1.8% respectively, after reporting stronger-than-expected profits. Mondelez International and Colgate-Palmolive also reported positive results, with their stocks rising 3.9% and 2.3%.

The cryptocurrency market also experienced a downturn, with Bitcoin falling below $77,000 from earlier highs. This decline followed a hack on the Binance cryptocurrency exchange, with a blockchain intelligence firm suggesting a North Korean unit was likely responsible for the theft of over $6 billion in crypto assets. Coinbase Global fell 10.6% despite reporting better-than-expected quarterly earnings.

In international markets, South Korea's Kospi dropped 3.5%, mirroring the concerns surrounding AI's impact on tech-heavy markets. Japan's Nikkei 225 fell 2.1% after the Bank of Japan decided to maintain its interest rates, similar to recent decisions by the Federal Reserve and the European Central Bank.

The U.S. Treasury yields eased, signaling a move towards safer assets, with the 10-year Treasury yield falling to 4.93%. This occurred even as oil prices saw an increase, with Brent crude rising 2.4% to $113.43 per barrel.
