Indian stocks erased their shy gains in morning trading to close marginally lower on Wednesday, as the lack of new catalysts drove markets to continue updating their outlooks for next year. The BSE Sensex eased 0.1% to 85,409 and the NSE Nifty 50 fell 0.1% to 26,140. While recent data indicated that Indian growth remained robust and slow inflation allowed the RBI to loosen financial conditions, fresh increases in benchmark prices of crude oil and base metals upheld caution for Indian assets. Major sectors were mixed, with TCS and Infosys closing relatively near the flatline among tech giants while ICICI Bank and HDFC Bank both edged lower for financial services providers. Indian stock markets will be closed on Thursday for Christmas holidays.
