Mumbai: Bombay Stock Exchange benchmark Sensex climbed over 84 points in opening trade on Tuesday, snapping a four-session losing streak on the back of a fresh spell of buying in oil and gas, metals and banking stocks amid a firming trend on other Asian bourses.

BSE Sensex, which has lost over 228 points in the previous four sessions, suddenly regained by 84.37 points, or 0.45 percent, to 18,350.40 in the first few minutes of trade on Tuesday, with select blue-chips leading the recovery.

The wide-based National Stock Exchange Nifty index regained the 5,500 points level by rising 27.20 points, or 0.46 percent, to 5,510.00.

Brokers attributed the rise in select stocks to fresh buying by funds and retail investors, driven by a firming trend on other Asian bourses.
