Mumbai: A smart rally in Infosys Tech and SBI aided the SENSEX to end in positive territory in extremely volatile activity on the Bombay Stock Exchange (BSE) on December 11 on alternate bouts of buying and selling by Foreign Institutional Investors (FIIs) and speculators.

The BSE Benchmark 30-share Index opened firm at 3,298.94 and later fluctuated erratically in a range between 3,324.23 and 3,287.28 before ending at 3,303.27 as against the previous close of 3,289.68, netting a rise of 13.59 points or 0.41 per cent.

The broad-based BSE-100 Index also improved further by 4.63 points to 1,621.50 from previous close of 1,616.87.

FIIs were believed to be consistent buyers in a few blue-chip shares during the session but the market later turned volatile ahead of Assembly elections in Gujarat as local operators anticipated political uncertainty in case of the Bharatiya Janata Party's (BJP) defeat in the election, brokers said.

Initial rally was well supported by the government's initiatives to speed up reforms, particularly privatisation process and a smart recovery on Wall Street on December 10.
