Stock futures trade mixed after tech sector sell-off Stock futures are experiencing a mixed trading session following a sell-off in the tech sector. The sell-off was triggered by concerns over the potential risks and costs associated with artificial intelligence (AI) spending. This has led to a decline in tech stocks, with the Nasdaq falling more than 2% for its worst day since June. The tech sector has been a significant driver of the market's growth in recent years, but the current sell-off has raised concerns about the sustainability of this trend. The decline in tech stocks has also had a ripple effect on other markets, with oil prices reaching a five-month high and global stocks experiencing a wobble. In the UK, retail sales have also seen a decline, with shoppers cutting back on spending. This has added to the overall uncertainty in the market, making it difficult for investors to make informed decisions. The S&P 500 and Nasdaq have both ended the day sharply lower, with the tech sector being the main contributor to the decline. The sell-off has been driven by revived doubts about the potential returns on investment in AI, which has led to a flight into treasuries and a decline in yields. The current market volatility is a result of a combination of factors, including the uncertainty surrounding AI spending and the impact of rising oil prices. As investors continue to navigate this uncertain market environment, it remains to be seen how the tech sector will recover and what the future holds for the market.
