The Nifty chart for monthly expiry is likely to consolidate within the bands of 21500 and 21700, with support at 21,300. A breakout on either side would confirm a directional move, with a move above 21700 inducing an up move. The negative correlation between Nifty Bank and Nifty IT is expected to continue as HDFC Bank stock selloff has been contained. Rail stocks like IRFC and RVNL continue to gain momentum, making them attractive for trading. Top ideas for the week include buying RITES, BPCL, and OIL stocks.
