IT stocks rallied on Wednesday as the rupee’s steep fall past Rs 90 per dollar sparked strong buying in export-driven technology names. The currency’s drop to a record-low 90.13 boosted sentiment for dollar-revenue earners, pushing the Nifty IT index up 1%. Wipro led with a 2% jump, followed by gains in TCS, Infosys, Mphasis, Tech Mahindra and other IT majors.
