After TCS announced a rather muted performance for October-December, another IT bellwether, Infosys, will announce its quarterly numbers on Thursday. Some brokerages believe Infosys can surprise positively and maintain guidance in spite of the Chennai flood impact. Ahead of results, Infy futures added healthy open interest. Option trading indicates the stock could dip to a low of ₹980 and rise to a high of ₹1,160. Apart from Infy, Cyient and Mastek will also announce results.
