The Nifty 50 climbed to 25,709 and Sensex closed near 83,952 ahead of Diwali week, driven by FII inflows and strength in banking and FMCG stocks. Analysts expect fresh record highs as festive optimism and Q2 earnings support sentiment. Buying interest remains broad-based with PSU banks and consumption sectors leading the rally. Traders foresee short-term consolidation before another breakout above 26,000, while foreign fund inflows continue to anchor overall market resilience amid positive global cues.
