The market gave a strong performance for the second straight day on May 18, with the Nifty50 closing above 15,100 levels and the Sensex above 50,000-mark. Buying was witnessed in banking & financials, auto, metals and IT stocks.
The BSE Sensex rallied 623 points or 1.26 percent to 50,203.73, while the Nifty50 jumped 184.90 points or 1.24 percent to 15,108.10 and formed a bullish candle on the daily charts.
"The short term trend of Nifty continues to be positive. The unfilled opening upside gap and a formation of small positive candle could hint at a possibility of profit booking emerging from the highs. Hence, bulls need to be cautious at the swing highs," Nagaraj Shetti, Technical Research Analyst at HDFC Securities told Moneycontrol.
"Nifty not showing any profit booking in the next couple of sessions could open the next upside levels of 15,450-15,500 in the near term. Immediate support is placed at 15,000 levels," he said.
The broader markets outperformed frontline indices with the Nifty Midcap 100 index rising 1.83 percent and the Nifty Smallcap 100 index climbing 1.59 percent.
