Mumbai: BSE(Bombay Stock Exchange) benchmark, Sensex  opened about 165 points up on buying on Thursday, spurred by a normal monsoon forecast and expectations of better quarterly results from Reliance Industries and Tata Consultancy amid a firming trend overseas.

The 30-share index rose by 164.51 points or 0.84 per cent to 19,635.49 points in opening trade where it had gained nearly 380 points in the previous two sessions.

Brokers said that expectations of industry giants Reliance Industries and Tata Consultancy may come out with encouraging Q4 earnings, to be announced later on Thursday, supported the upward trend.

They also said that the sentiment was bullish on continued buying by foreign funds and retail investors, driven by firming trend on Asian bourses followed by overnight gains at the US market.
