Indian benchmark indices end with declines amid bearish trends, led by selling pressure in IT, auto, and bank stocks. S&P BSE Sensex settles at 71,139.90, down 801.67 points or 1.11%. Nifty closes with declines of 215.50 points or 0.99% at 21,522.10. Analysts suggest that a significant decline below the important support level of 21,500 could initiate a market correction.
