MUMBAI: Caution-selling combined with profit-booking and negative global indices dragged the Indian equity markets lower on Tuesday.

Consequently, the 30-scrip Sensex of the Bombay Stock Exchange (BSE) provisionally closed the day's trade down 379 points, or 1.59 percent.

Similarly, the wider 50-scrip Nifty of the National Stock Exchange (NSE) ended the day's trade in the red by 132.25 points, or 1.83 percent, at 7,102.30 points.

During the intra-day trade, the Sensex touched a high of 23,851.51 points and a low of 23,361.94 points.

The BSE market breadth was heavily tilted towards the bears -- with 1,890 declines and 717 advances.

Initially, the Sensex of the Indian equity markets opened on a positive note, following the recent uptrend and Monday's positive close at the U.S. indices.

However, caution-selling at the start of the Budget session of Parliament dragged the equity markets lower.

Profit-booking on the gains made in the past few sessions and a weak rupee also dented investors' sentiments.

Investors' confidence was eroded by the continuing conflict between the ruling National Democratic Alliance and the opposition, which is seen as having a bearing on some key economic legislations that await parliamentary approval.

The government is expected to push through major economic legislations like bankruptcy code and Goods and Services Tax (GST) Bill during the ongoing Budget session.

In addition, a weak rupee kept investors' unnerved. The rupee opened at 68.66 to a U.S. dollar from its previous close of 68.60-61 to a greenback.

On Monday, the rupee weakened by 14 paise to touch its 30-month closing low. This level was last seen during late August 2013.

Besides, softening of crude oil prices which declined by 1.95 percent to $32.7 and negative Asian and European markets, deterred investors to chase stock prices higher.

Caution also prevailed over the upcoming G20 finance ministers' meet in Shanghai, China.

"Caution over the budget session amidst political tensions and softening of crude oil prices set in a negative bias," Anand James, co-head, technical research desk with Geojit BNP Paribas Financial Services, told IANS.

"Investors were seen reluctant to chase prices due to the budget session and F&O (future and option) expiry."

Vaibhav Agarwal, vice president and research head at Angel Broking, elaborated that markets witnessed profit booking after four consecutive sessions of gains on the back of weak Asian cues.

"We expect volatility to increase towards the end of this week in anticipation of the budget," Agarwal noted.
