As posted yesterday, markets showed bullishness in the early hours of yesterday and witnessed profit booking in the later half, with indices turning volatile due to expiry. There was a good fight at the 17500 options strike, but eventually bulls had the upper hand. Now in this pullback, Nifty should hold 17300-350 levels for this rally to remain intact. Else we might see resumption of the downtrend. While Nifty has some strength, the chart structure and indicators are not giving confidence of this being a sustainable rally. Also remember, we are bouncing from 15600 levels so 2000 points rally is done.
