Mumbai: Profit booking, combined with negative global cues and a weak rupee, subdued the Indian equity markets on Tuesday. Consequently, the key indices provisionally closed the day's trade marginally in the red as heavy selling pressure was witnessed in banks, capital goods and healthcare stocks. The wider 51-scrip Nifty of the National Stock Exchange (NSE) edged lower by 18.60 points, or 0.23 per cent, at 8,219.90 points. The barometer 30-scrip sensitive index (Sensex) of the BSE, which opened at 26,907.42 points, provisionally closed at 26,812.78 points (at 3.30 p.m.) -- down 54.14 points or 0.20 per cent from the previous close at 26,866.92 points. The Sensex touched a high of 26,925.64 points and a low of 26,754.60 points during the intra-day trade. In contrast, the BSE market breadth was slightly tilted in favour of the bulls -- with 1,306 advances and 1,295 declines. Both the key Indian indices ended in the green on Monday, following economic reforms and higher global equity markets. The barometer index had surged by 241.01 points or 0.91 per cent, while the NSE Nifty had risen by 68.30 points or 0.84 per cent.
