MUMBAI (Reuters) - India's stock markets traded rangebound on Tuesday as software exporters such as Tata Consultancy Services fell after revenue warnings by some of its smaller rivals, while Sun Pharmaceutical Industries rose after Credit Suisse said the company has raised prices of some drugs.
Companies including Tech Mahindra , Persistent Systems and KPIT Technologies have warned that revenue would be lower than expected in the April-June quarter due to delay in capex at key clients and cross-currency shifts.
Foreign portfolio sales worth 91.55 billion rupees ($1.44 billion) over the past two months also weighed on sentiment.
"Slowly many companies are coming forward and giving poor guidance. This quarter, like previous few, may not be great," said Aneesh Srivastava, chief investment officer at IDBI Federal Life Insurance.
The 30-share BSE Sensex rose 0.03 percent, while the 50-share Nifty gained 0.2 percent.
