The stock market faced significant declines as concerns over high spending in the artificial intelligence (AI) sector and escalating geopolitical tensions led to a widespread sell-off. Major indices like the Nasdaq experienced sharp drops, with the index plummeting more than 750 points, marking its worst performance since June. This downturn was accompanied by a surge in oil prices, which exceeded $113 per barrel, further exacerbating market fears. Investors expressed anxiety over the sustainability of heavy investments in AI, particularly following disappointing earnings from major tech firms such as Meta and Tesla. As a result, stock futures traded mixed, indicating ongoing uncertainty in the market. The combination of rising oil costs and fears of renewed conflict in the Middle East continued to weigh heavily on investor sentiment, resulting in a significant retreat from tech stocks and a broader sell-off across global markets.
