After opening flat, the market remained in a consolidation mode throughout the session and finally settled with moderate losses on the expiry day of December derivative contracts, December 30. The broader markets closed mixed with the Nifty Midcap 100 falling 0.37 percent and Smallcap 100 index gaining 0.24 percent.
The BSE Sensex was down 12.17 points at 57,794.32, while the Nifty50 declined 9.60 points to 17,204 and formed Doji kind of pattern on the daily charts.
"Nifty50 opened on a flattish note and consolidated throughout the session in a narrow range. It managed to sustain above the 20-day simple moving average SMA (17,154), with a Doji candle formation," says Karan Pai, Technical Analyst at GEPL Capital.
He further says the candle pattern suggests that the index is still in an indecisive phase. "The price action suggests shrinking volatility and also points towards the possibility of the prices moving in a tight range of 17,000-17,300."
