Stocks in India advanced for the second day in a row on Thursday as traders covered shorts and rolled over their derivatives contracts that were set to expire later in the day. Also helping the rally was a strong showing from Indian software stocks such as Wipro ( WIT) and Infosys ( INFY), following a move by Citigroup ( C) that raised its earnings estimates for the software sector due to an adjustment higher for the rupee against the U.S. dollar. "The markets rose on continued short-covering. We may, however, see unwinding of positions if inflation data is weak tomorrow," said Bhaskar Kapadia, a partner with brokerage Pyramid Securities. The Bombay Stock Exchange's Sensex Index rose 201.75 points, or 1.4%, to 14,422.82. Here's a look at how some India-based American depositary shares traded in the U.S. on Thursday. Satyam Computer Services ( SAY), an India-based consulting and information technology service provider, announced it has formed a strategic alliance with U.S.-based Sciformix Corporation, a life science knowledge process outsourcing firm, to deliver end-to-end data management services in Pharmacovigilance.
