Le saignement technologique se poursuit à Wall Street: Nvidia perd son trône de société la plus précieuse face à Apple

The tech sector has continued its downward spiral on Wall Street, with NVIDIA losing its position as the world's most valuable company to Apple. The shift marks a rare reversal in market dynamics, driven by sharp declines in Asian markets and investor skepticism toward high valuations in technology stocks. The sell-off began in Asia, where major indices such as the KOSPI and Hang Seng Index saw steep drops. By mid-morning, the KOSPI had fallen over 6%, while the Nikkei 225 dropped more than 4%. These losses have rippled through global financial markets, influencing trading activity in Europe and the United States. In New York, the Nasdaq Composite opened sharply lower, declining 1.74% as investors reassessed the growth prospects of tech firms, particularly those tied to semiconductor manufacturing and artificial intelligence. NVIDIA, which had held the title of the world’s most valuable company since April 2025, saw its stock price fall more than 4% during early afternoon trading. At one point, its market capitalization dipped below $4.816 trillion, allowing Apple to reclaim the top spot with a valuation of approximately $4.904 trillion. This move was unprecedented, as Apple had previously surpassed NVIDIA in April 2025 before being overtaken again. The decline reflects broader concerns about the sustainability of rapid gains in the tech sector, especially after a year marked by aggressive price increases. Investors are increasingly questioning whether the lofty valuations of companies like NVIDIA, Microsoft, Alphabet, and Meta are justified given current economic conditions and technological progress. The sell-off comes amid a period of heightened volatility, with many tech stocks experiencing significant swings in value. Analysts suggest that the recent downturn is partly due to fears of slowing demand for semiconductors and AI-related products, compounded by geopolitical tensions and inflationary pressures. In Europe, the semiconductor industry has also felt the impact. ASML, the largest publicly traded company in the region, fell over 4.4% in early trading, dropping below €600 billion in market value. This decline highlights how interconnected global markets have become, with movements in one region quickly affecting others. The leadership change at the top of the tech sector underscores a growing divergence in performance among major players. While Apple continues to benefit from its diverse product portfolio and strong brand loyalty, NVIDIA faces challenges related to supply chain disruptions and shifting consumer preferences. Meanwhile, other tech giants such as Microsoft and Alphabet have also been affected, though their share prices have remained relatively stable compared to NVIDIA. Market observers expect further fluctuations in the coming weeks, as investors continue to adjust their positions based on new data and evolving economic indicators. With the tech sector representing nearly 40% of the U.S. market, any sustained downturn could have wide-reaching implications for the broader economy. Investors will likely remain cautious, waiting for clearer signals before making substantial moves in the sector.
