Last week Nifty and Bank Nifty Index traded lower after striking a high on Monday.
The Bank Nifty Index is trading in a weak zone. Bank Nifty needs to sustain or close above the 32900-950 range to enter the positive trading zone.
But Nifty 50 Index last to last weekly close was positive, and Index is managing that point well.
Next week 14480-590 range will play a crucial role for the Index. If bulls hold the range mentioned above next week with a positive build-up on a weekly time frame, then Index can bounce back.
