Equity benchmark Sensex jumped over 400 points in opening trade on Tuesday tracking gains in financial stocks on Reserve Bank support amid tepid cues from global markets.

After hitting a high of 32,164.65, the 30-share index pared gains to trade 151.91 points or 0.48 per cent higher at 31,894.99. Similarly, the NSE Nifty advanced 60.05 points, or 0.65 per cent, to 9,342.35.

In the previous session, the BSE barometer settled 415.86 points or 1.33 per cent higher at 31,743.08, while the Nifty closed 127.90 points, or 1.40 per cent, to 9,282.30.

Foreign portfolio investors were net sellers in the capital market on Monday, as they offloaded equity shares worth Rs 916.42 crore, according to provisional exchange data.

The Reserve Bank of India's Rs 50,000-crore liquidity booster to the mutual fund industry has spurred buying in financial stocks, traders said. Expectation of another stimulus package by the government has also buoyed investor sentiment, they added.
