<h1>Sensex and Nifty rose on India-US trade optimism, FII inflows and rupee gains amid mixed Q3 earnings.</h1> Sensex and Nifty advanced for a third straight session on optimism over an India-US trade agreement and positive global cues; Sensex closed at 84,273.92 and Nifty at 25,935.15 after intraday highs, with sectoral winners offset by some large-cap laggards. The rise was attributed to easing tariff concerns, renewed foreign institutional investor inflows and rupee appreciation, while mixed Q3 earnings and profit-booking were expected to shape near-term market direction.
