BENGALURU, Dec 1 (Reuters) - Indian shares rose on Wednesday, boosted by IT, metals and auto stocks, after data showed India grew at a faster pace than any major economy in the September quarter.

By 0510 GMT, the blue-chip NSE Nifty 50 index rose 1.04% to 17,158.60 and the benchmark S&P BSE Sensex climbed 1.02% to 57,645.99.

India's gross domestic product (GDP) expanded 8.4% in the July-September quarter, but economists said disruptions from the Omicron coronavirus variant risked slowing the recovery, given the country's low vaccination rates.

"Among domestic factors, most economic indicators are doing well. GDP data was strong and Goods and Services Tax collections are expected to be higher," said Pankaj Pandey, head of research, ICICIdirect.

He, however, said concerns around accelerated tapering by the U.S. Federal Reserve weighed on the market.

Providing further support to the market, a private survey showed India's manufacturing activity in November grew at the fastest pace in 10 months.

Information technology and metal stocks rose the most among major Nifty sub-indexes, gaining 1.74% and 1.86%, respectively.

ICICIdirect's Pandey said the IT rally could be attributed to sectoral rotation and investors being comfortable with the growth outlook structure of tech companies.

Shares of Maruti Suzuki India rose as much as 3.29%. The country's biggest carmaker said despite semiconductor shortages, production at two of its manufacturing units would be around 80% to 85% of normal capacity in December - much higher than the production figures for September and October.

The Nifty Auto index climbed 1.6% ahead of November auto sales figures due later in the day.
