The S&P BSE Sensex declined by 112.37 points, closing at 20111.61, driven down by weak global cues and a falling rupee, with rate-sensitive sectors like reality and auto facing significant losses. Major pharmaceutical stocks also suffered declines due to a new drug policy, while Coal India's net profit surged, benefiting its stock performance. Overall market breadth was negative, with more declining stocks than advancing ones across various indices.
