BENGALURU, Nov 29 (Reuters) - Indian shares traded flat after opening lower in a volatile session on Monday on gains in heavyweight Reliance as well as metal and technology stocks amid a global market rebound on hopes that the new coronavirus variant would likely be mild.

"After last week's fall, we are seeing some volatility in the markets. However, sentiment is steadying globally after reports that the new coronavirus variant may not be as lethal as first thought," said Ajit Mishra, VP Research, Religare Broking.

Mishra also said that all sectors, barring pharma, are seeing some pressure, and stocks of hotels, aviation and multiplex chains were likely to be the most affected on the variant news.
