The technology sector is experiencing a significant sell-off in the pre-market session, driven primarily by a sharp increase in U.S. Treasury yields, which have reached their highest levels since 2007. This surge in yields is weighing on growth stocks, as it diminishes the present value of future earnings. This downturn is part of a broader market decline, with futures for the Dow, S&P 500, and Nasdaq all trading lower amid concerns over potential Federal Reserve rate hikes and geopolitical tensions.
