Mumbai: The BSE benchmark Sensex rose by 115 points in opening trade on Wednesday on the emergence of buying at existing lower levels, driven by a firming trend on other Asian bourses.

The 30-share BSE index, which has lost over 832 points in the previous three sessions, recovered by 115.60 points, or 0.73 percent, to 15,980.46 in the first five minutes of trade on buying in fundamentally strong stocks available at attractive lower levels.

In a similar fashion, the wide-based National Stock Exchange Nifty index moved up by 34.45 points, or 0.72 percent, to 4,806.60.
IT, metal and realty stocks accounted for the lion's share of the gains.

Brokers attributed the initial rise in the stock market to a firming trend on other Asian bourses in tandem with the overnight recovery in US equities.

Meanwhile, in the Asian region, Japan's Nikkei Index was trading marginally higher by 0.42 percent in early trade on Wednesday.

The Dow Jones Industrial Average ended 1.44 percent higher in Tuesday's trade.
