BENGALURU, May 22 (Reuters) -

Indian shares recovered from a subdued start on Monday, led by the gains in information technology and pharmaceutical stocks, as investors saw buying opportunities at key levels ahead of the resumption of debt ceiling talks in the United States.

The blue-chip Nifty 50 index was up 0.31% at 18,261.80 as of 10:12 a.m. IST, while the benchmark S&P BSE Sensex rose 0.21% to 61,863.92.

Nine of the 13 major sectoral indexes logged gains, with high-weightage financials marginally rising.

Information technology stocks rose 1% and was the top sectoral gainer. All 10 constituents of the IT index advanced.

Pharma stocks also advanced 1%, aided by the uptick in Divi's Laboratories Ltd and Abbott India Ltd after posting a rise in March-quarter profit.

"A market rebound from major support levels signals bullishness," said Deven Mehata, equity research analyst at Choice Broking. "Positional traders can purchase declines with suitable stop-loss near the support level of 18,050 levels."

Power Grid Corporation of India Ltd

rose

over 2% and was among the top gainers in the Nifty 50 index after reporting a rise in March-quarter profit.

Glenmark Pharmaceuticals Ltd
