Sensex plunging 1,281.68 points (1.5%) to close at 81,148.22, and the NSE Nifty50 declining by 346.35 points (1.39%) to settle at 24,578.35.  

Key Factors Behind the Decline:

• Profit Booking: The sharp rally on Monday, driven by easing geopolitical tensions and positive global cues, led investors to book profits, resulting in a broad-based sell-off.
• Sectoral Weakness: IT and FMCG sectors were among the top laggards. Infosys dropped 4%, and Power Grid fell 3%, dragging the indices lower.  
• Geopolitical Concerns: Despite a ceasefire between India and Pakistan, underlying tensions persisted, causing investor apprehension.  
• Global Trade Dynamics: The US-China trade truce raised concerns about increased competition for India, potentially impacting exports.
