With the rupee fall to the historic low of 65 against the U.S. dollar, TCS, Infosys and Wipro will be the biggest gainers. These companies will approximately gain an additional 5,700 crore, 3,600 crore and 2,700 crore, respectively by the end of 2013-14.

Amit Khurana, director (research) at Dolat Capital said, “A weaker rupee would help India's exporters. Nearly 40 percent of the Sensex stocks benefit from the rupee's fall.”

It’s not just individual companies that benefit from the weak rupee but a range of sectors like IT, pharmaceuticals, hotels, textiles and automobiles are some of the industries that are gaining from the rupee fall.

"Dollar appreciation would be positive for sectors such as IT and pharma, which have earnings in foreign currency," said Pankaj Pandey, head of research at ICICI Securities.

"The best business model anyone can have is to spend in rupees and earn in dollars, which is what the big boys of India Inc, including the top IT companies, excel in," said a leading industrialist, requesting anonymity.
