The benchmark Sensex surged 376 points today, clocking its biggest gain in seven weeks, ahead of retail inflation figures and on expectations the US Federal Reserve would ease tapering after disappointing jobs data.
Investors also expect the RBI to keep interest rates unchanged in a bid to support growth after the Index of Industrial Production contracted 2.1 per cent in November. There were hopes of inflation easing amid increased availability of winter crops.
There was buying across the board as 11 out of the 12 BSE sectoral indices advanced, led by IT, Teck, Oil & Gas, Banking and Capital Goods stocks. Only the Healthcare index fell.

The Fed said it would reduce its bond-buying programme, which has been a source of liquidity for most Asian and emerging markets, from this month. US employment rose at the slowest pace in three years in December, according to a government report.
"Markets rose sharply on Monday, likely buoyed by the weak payroll data in US, which re-ignited optimism on the Fed taper programme. Expectations on the CPI inflation data which is due post-market hours, also kept the markets up," said Dipen Shah, Head - Private Client Group Research at Kotak Securities.
The 50-share CNX Nifty on the National Stock Exchange shot up 101.30 points, or 1.64 per cent, to 6,272.75.
"The markets seem to be anticipating a healthy inflation figure, since that would reinforce that the RBI's decision to not raise the headline repo rate last month was the correct decision," said Raghu Kumar, Cofounder of RKSV.
Ahead of the RBI's monetary policy review on January 28, Economic Affairs Secretary Arvind Mayaram has pitched for shifting the policy focus to growth as interest rates do not have a bearing on food inflation. The government is scheduled to release data for retail inflation today.
Foreign institutional investors bought shares worth a net Rs 68.16 crore last Friday, according to provisional data from the stock exchanges.

"The markets are anticipating some positive news from the inflation figures scheduled to be released later in the evening, which will prompt RBI to take some growth-boosting measures that will be good for the market," he said.
