Mumbai: A key index of Indian equities markets closed 88 points lower Friday owing to a fall in metals, IT and telecom stocks. Though market conditions were volatile through the day, mid- to small-sized company scrips helped steady broader market fluctuations. The sensitive index (Sensex) of the Bombay Stock Exchange (BSE), which opened lower at 16,679.99 points, shut shop at 16,693 points, 88.43 points or 0.53 percent lower than Thursday's close of 16,781.43 points. The S&P CNX Nifty of the National Stock Exchange (NSE), too, closed in the negative terrain at 4,958.95 points, down 0.55 percent. Broader market indices managed to stay in the green, with the BSE midcap index closing 0.65 percent higher and the BSE smallcap index moving up 0.91 percent. Healthcare stocks were the flavour of the day, while energy and consumer durable scrips too found some favour among buyers. However, metals, IT and telecom scrips brought the Sensex down, with banking and capital goods stocks adding to the drag. Thanks to the mid- and small-sized company stocks, the market breadth was positive, with 1,628 stocks advancing, 1,137 declining and 90 remaining unchanged. Among the gainers on the Sensex were Sun Pharma, up 7.04 percent at 1,311; Reliance Industries, up 1.21 percent at 2,129.80; ITC, up 1.01 percent at 234.75; and ONGC, up 0.75 percent at 1,157.30.
