MUMBAI (Reuters) - India's stock markets edged lower on Tuesday, posting a second consecutive losing session as software stocks remained under pressure a day after Infosys Ltd trimmed its U.S. dollar revenue growth guidance. Infosys fell 2.09 percent, adding to its 3.8 percent loss on Monday. But Tata Consultancy Services Ltd , which is expected to report earnings later in the day, gained 0.23 percent after earlier falling to as much as 1 percent. The broader Nifty lost 0.15 percent to end at 8,131.70. The benchmark BSE Sensex lost 0.21 percent to end at 26,846.53.
