Nifty IT fell 2.25% Friday, extending losses as US tariff fears weighed on sentiment. Persistent and Mphasis led declines, while TCS and Infosys slipped over 1.3% each. SEBI RA A&Y Market Research warned tariffs up to 50% on Indian IT exports could trigger a downside re-rating. Despite strong fundamentals, near-term underperformance and volatility remain likely for the sector.
