The BSE Sensex fell for a second consecutive day on Thursday as investors took profits on expiry of monthly derivatives amid concerns about high oil prices.

The 30-share BSE index closed down 0.37 percent, or 66.75 points, at 18,078.50, after climbing into positive territory for some time. Eighteen of its components declined.

The markets were choppy because of the expiry of the derivatives contracts today, said Neeraj Dewan, director at Quantum securities in New Delhi.

From tomorrow the focus will be on global markets and if the U.S. markets close higher we could have a positive opening. If the oil situation gets murky it will affect Indian markets, he said.

India looks vulnerable to profit-taking in the short term after recent outperformance, rising oil prices, and seasonally tighter monetary conditions, UBS said in a note.

An initial public offer by Multi Commodity Exchange (MCX) to raise up to $134 million was fully covered on Thursday, the second day of the sale, indicating investors were shifting their money to new offerings.
