With the benchmark indices scaling new highs on a daily basis and the broader market also catching up with the trend, the question in the air is whether the Nifty 50 will hit the 18,000 level first or the Sensex 30 will outpace its NSE counterpart to hit 60,000 level. This discussion itself is an indication that the bulls will continue to tighten their grip on the market in the next few weeks. The Sensex closed at 58,129.95, while the Nifty ended the week at 17,323.60.
