Mumbai: The BSE benchmark Sensex extended its gains for the sixth day by adding another 104 points in opening trade on Thursday as funds and retail investors engaged in enlarging their positions, taking cues from the firming trend on other Asian bourses.

Investors covering their short positions on the last day of June month settlement in the derivatives segment further fuelled the uptrend.

The 30-share index of the Bombay Stock Exchange, which has gained over 1,145 points in the previous five sessions, moved up further by 104.42 points, or 0.56 percent, to 18,798.28 in opening trade.

In a similar fashion, the broad-based National Stock Exchange Nifty index rose by 28.75 points, or 0.51 percent, to 5,629.20.
Stocks of realty, FMCG, capital goods, auto and banking companies attracted the most interest in early trade, helping the Sensex to rise.

Brokers said besides the firming trend on other Asian bourses, overnight gains in the US market influenced the trading sentiment.

Meanwhile, Hong Kong's Hang Seng index was trading 0.63 percent higher and Japan's Nikkei was up by 0.42 percent in morning trade on Thursday. The US Dow Jones Industrial average ended 0.60 percent higher in the previous session.
