The Sensex and the Nifty rose nearly 0.4 per cent, led by gains in export-focussed companies after the rupee fell to a near two-year low in early trade, while bullish brokerage calls also helped drugmakers such as Sun Pharmaceutical Industries.

The dollar has surged by almost 20 per cent against a basket of major currencies in the past year as expectations have grown that the US Fed would become the first major central bank to hike rates since the financial crisis.

Upbeat economic data from the United States and a weak rupee are helping IT stocks, said Alex Mathews, head of research at Geojit BNP Paribas.

Shares of export-focussed companies led the gains. Sun Pharmaceutical Industries rose 4.32 percent after Bank of America Merrill Lynch upgraded the stock to "buy" from "neutral", citing the company's integration with Ranbaxy Laboratories, price hikes at unit Taro and improvement in US supplies as key reasons.

Glenmark Pharmaceuticals shares jumped 3.48 per cent after the company received final approval from the US FDA for a copy of Bayer's Yaz contraceptive drug.

A report by Goldman Sachs said: "Recent activity data is coming in a tad better, with our current activity indicator showing an uptick in Q2. July data on PMI, auto sales, and indirect tax collections have also shown an improvement.Corporate results for Q1, FY16 show some tentative positive signs, though sales and earnings growth remain weak. While July headline CPI inflation came down significantly in yoy terms, we would advise caution as the month-on-month decline was not as large. We continue to expect the RBI to remain on hold through FY16 due to recent FX weakness, long monetary transmission lags and uncertainty about the impact of monsoons, as well as the potential impact of an impending Fed rate hike. After the recent CNY depreciation, we have revised our 3, 6, and 12m USD-INR targets to 64.5, 65, and 65. We think that INR will likely outperform the region due to a strong balance of payments driven by lower oil prices and higher FDI inflows. In the policy front, while legislation on GST has stalled, there has been some progress on bank reforms and some big-ticket announcements have been made on FDI."
