Domestic stock markets gave up all of intraday gains in late morning deals on Friday, after a positive start amid gains in Asian peers. The S&P BSE Sensex index fell as much as 211.02 points from the day's high to 39,464.23, and the NSE Nifty benchmark moved to 11,803.85, receding 67.85 points from its intraday high. Weakness in banking and metal stocks offset the advances in IT and pharmaceutical shares. Earlier in the session, the Sensex and Nifty had climbed to intraday highs of 39,675.25 and 11,871.70 respectively.
