A sudden shift in market sentiment occurred after US President Donald Trump's remarks about Iran, causing significant declines in several Nifty 50 stocks. Following Trump's warning of severe retaliation against Iran, crude oil prices surged over 4%, reaching nearly $105 per barrel, which triggered a risk-off mood across global markets. Stocks like Trent and InterGlobe Aviation, which had previously surged nearly 7% and 6% respectively, saw declines of over 2-3% in early trading on April 2, resulting in a two-day swing exceeding 9%. Other stocks, including Adani Ports and the State Bank of India, also faced sharp declines, reflecting a broad-based sell-off across sectors. Market analysts noted that such volatility is typical during uncertain global conditions, where high-beta stocks experience exaggerated movements. The sell-off follows a strong market rally on April 1, where the Sensex gained 1,186.77 points, driven by optimism around easing geopolitical tensions. However, Trump's aggressive stance has dampened those hopes, leading to increased selling pressure from foreign portfolio investors (FPIs) and contributing to a weakening rupee.
