Tech stocks fall as DeepSeek disrupts market

Global technology stocks experienced a sharp decline on Tuesday, with a second day of losses triggered by the emergence of a low-cost Chinese AI model. This new AI assistant, launched by China’s DeepSeek, has raised doubts about the dominance of established AI leaders like Nvidia and OpenAI. Nvidia’s shares plummeted 17% on Monday, erasing $593 billion from its market value. Other major tech companies such as Broadcom, Microsoft, and Alphabet also saw significant declines, fueling broader market concerns.

The unexpected launch of DeepSeek’s AI, which claims to use fewer data and lower costs than existing models, has disrupted the market, causing scepticism among investors. While OpenAI CEO Sam Altman praised the model, calling it ‘impressive,’ the sudden rise of a competitor from China has surprised many and highlighted the rapid pace of advancements in AI technology. This development has led to a global sell-off in tech stocks, with significant drops in companies across the US, Europe, and Japan.

The sell-off has raised concerns about the high valuations of AI and tech stocks, which have seen inflated prices due to the AI boom. Nvidia, for example, had been trading at nearly 60 times its earnings, far above the broader market’s 22 times. The market downturn underscores the risks tied to the heavy concentration of tech stocks in investor portfolios, with many fearing that the industry’s rapid expansion has created an unsustainable bubble.

This market shakeup also reflects the broader issue of leverage in the system, with investors increasingly borrowing to buy high-priced tech stocks. As a result, the unwinding of these positions, combined with algorithmic trading, has intensified the sell-off. With key earnings reports from companies like Apple and Microsoft expected this week, investors are closely watching how tech executives address concerns about capital spending and the future of AI investments.
