The benchmark BSE Sensex rose 0.3% to 34,592.39 on Friday and the Nifty 50 Index climbed 0.3% to 10,681.25, boosted by the overnight rally on the Wall Street. The indexes posted a weekly advance of 1.3% and 1.2% respectively.
Except Wednesday, Indian equities rose all other days of the week, as positive global growth outlook continued to boost markets around the world. The Nikkei Asia300 Index of companies outside Japan has gained 0.6% since last Friday, adding to the more-than-3% advance in the previous week.
"The global backdrop is looking very good," said Akash Jain, vice president of research at Ajcon Global. "Company earnings could provide a further impetus to the Indian markets. Expectations are that the aggregate earnings of Sensex companies will see a double digit growth."
