Indian benchmark indices Sensex and Nifty closed higher on Tuesday, with Sensex gaining 0.25% to reach 63,323 and Nifty advancing 61 points to close at 18,816.70. All Nifty sectoral indices, other than pharma and media, ended in the green alongside broader markets. Global concerns were amplified as China cut interest rates, and investors await Powell's testimony to the US Fed in its July meeting, but the market was led by IT and Auto stocks' uptrend and increased fag-end buying in power and utilities shares.
