Indian equities fell sharply on Tuesday following weak global cues and persistent foreign institutional selling. The Sensex declined over 500 points to trade near 84,650, while the Nifty 50 slipped below 25,600. Metals, auto and IT sectors saw steep losses as traders booked profits after a recent rally. Broader midcap and smallcap indices also corrected 0.8% each. Market sentiment remained fragile ahead of key corporate earnings and the U.S. inflation print expected later this week, which may shape foreign investment flows.
