Sensex and Nifty ended largely flat on Monday after a highly volatile session, as strong gains in IT stocks helped benchmark indices recover from sharp early losses triggered by weak global cues, elevated crude oil prices and geopolitical tensions. At close, the Sensex rose 77.05 points or 0.10 percent to settle at 75,315.04, while the Nifty gained 6.45 points or 0.03 percent to 23,649.95. Broader market sentiment remained sharply weak through the session, with 2,891 shares declining against only 1,216 advances. IT stocks emerged as the biggest support for the market, while auto, PSU bank, media and metal stocks remained under pressure. India VIX also jumped nearly 4.5 percent, reflecting heightened volatility concerns.
