Short covering and positive global cues helped the BSE Sensex snap six-day losing streak and the Nifty close above 8000 level on Tuesday after volatility. The broader markets outperformed benchmarks with the BSE Midcap and Smallcap indices rising more than 1.1 percent. Commodities also bounced back after fall in dollar. The 30-share BSE Sensex was up 195.64 points at 25960.78 and the 50-share NSE Nifty climbed 73.20 points to 8002.30. The market breadth also turned positive as about 1475 shares advanced against 1083 declining shares on the BSE. Investors continued to avoid pumping in fresh money into markets due to demonetisation concerns and strengthening dollar. They maintained cautious stance ahead of Federal Reserve’s policy meeting in next month.
