U.S. markets experienced a sharp sell-off on February 3, 2025, as Dow and Nasdaq futures dropped over 650 points following the announcement of new tariffs by former President Donald Trump. The Sensex in India also faced a significant decline, sliding over 700 points, reflecting the global market's reaction to the tariff news. The tariffs, particularly targeting Mexico, have raised concerns among investors, leading to notable drops in shares of companies such as Sona BLW and Samvardhana Motherson, which fell by up to 8%. Analysts suggest that these tariffs could hinder revenue for affected companies, contributing to the overall market turmoil.
