Nifty is making fourth attempt to cross the level of 12,300 and in any case, the flat base breakout or closing above 12,300 means there would be another room for 100-175 points on the upside for the index. While a move below the 12,100 level would be the first sign of weakness. Stocks in news: Natco Pharma, JSW Energy, FDC, TCS, RITES.
