India's BSE Sensex pared early losses to close about 0.2% up at 75,318 on Wednesday, in another session marked by heightened volatility, supported by selective buying in heavyweights amid ongoing uncertainty. Geopolitics remained in focus, with attention also shifting to FOMC minutes later in the day. Traders stayed cautiously optimistic over a possible US-Iran deal, but conflicting signals from Washington and Tehran and ongoing disruptions to the Middle East supply continued to drive volatility in energy markets. Sectorally, strong buying in oil & gas, autos and banking indices contrasted with weaknesses in FMCG, IT and consumer durable stocks. Reliance Industries gained 2.8% and led the way, notching its biggest daily gain in over three years. Bajaj Finserv (1.3%), Trent (1%), IndiGo parent InterGlobe Aviation (1%), Axis Bank (1%) and M&M (0.9%) also advanced firmly.
