The Bombay Stock Exchange benchmark Sensex rose by 163 points in early trade on Friday on the back of buying by funds in heavy-weight stocks, triggered by firm global markets.
The BSE-30 share index, Sensex, which had gained 536.05 on Thursday, gathered another 162.87 points to 13,274.72.
Similarly, the wide-based National Stock Exchange's Nifty gained 43.80 points to 3,991.00.
Stock brokers said a marginal rise in the inflation, which inched up to 11.91 per cent for the week ended July 5, from 11.89 per cent in the previous week, failed to give any impact on the trading sentiments.
They said firm trends in global markets after crude oil prices declined further influenced the sentiments here. The Hong Kong's Hang Seng index opened up 0.7 per cent.
Major gainers, which supported the Sensex were Larsen and Toubro, HDFC Ltd, HDFC Bank, ICICI Bank, State Bank of India, Mahindra and Mahindra, DLF Ltd and Reliance Petroleum.
