Mumbai, Dec 13 The boom conditions at the Bombay Stock Exchange continued unabated and the sensex today went up by another 130 points to scale new peaks at 9,274.19 buoyed by a sustained buying spree by operators and retail investors coupled with fair amount of FII purchases.

Surpassing the crucial 9,175 resistance level, the BSE's Benchmark 30-share Sensitive Index headed for new peaks and hit a new intra-day high of 9,274.19 before even settling at a new closing peak of 9,263.90 against yesterday's close of 9,133.67, a net rise of 130.23 points or 1.43 per cent.

After a brief initial hesitancy, operators and retailers resorted to across-the-board buying support in a bid to cover their short positions ahead of the Federal Open Market Committee meeting tonight, which is expected to hike the US interest rates by a 25 basis point.

Even as the market factored this hike, brokers said investors seemed to be interested in the tone of speech of Fed's chairman on whether the rate hikes would continue at a measured pace or halt it.

The sentiment was bolstered by increased FII activity at the last weekend. Foreign Institutional Investors (FIIs) reported net investments of a hefty Rs 420.1 crore on Friday.

Contrary to a general belief of a correction, the sensex continued to climb as the bullish fervour turned further intensive helped by the government's pro-reform policies.

The government has revived its disinvestment initiative and plans to divest a part of its stakes in six profit-making non-navratna public sector undertakings (PSUs).

The government is also optimistic about the annual GDP growth rate, which is expected to be around 8-10 per cent. Heavyweights like RIL, SBI, Infosys Tech, ONGC, HDFC, ITC Satyam Computers, Grasim, Maruti Udyog, Tata Steel and L&T scored impressive gains.
