Reasons Behind the Sensex Drop

This increase in the investors selling off their shares is because they want to avoid trading with risky stocks and play safe trade amidst the increasing geopolitical issues due to the U.S trade. Analysts, as per reports, said that the major reason behind the decline is Donald Trump’s tariff threats and trade wars, which is leading to increased FII selloffs. 

Moreover, the mixed earnings of Q3 quarter of the current financial year and the uncertainty before the Union Budget release are also some of the reasons quoted by analysts behind the decline in Sensex. 

Vinod Nair, Head of Research, Geojit Investments Limited told Live Mint, "Domestic markets remained cautious ahead of the US Supreme Court’s ruling on Trump-era tariffs, with renewed uncertainty over US trade policy prolonging the recent consolidation. Continued FII outflows, rising U.S. and Japanese bond yields, and a weakening rupee weighed on investor confidence.”
