1. Looks like fall has been arrested at 21647 but still we cant rule out the possibility of nifty bank touching the strong support level of 21342. 2. In the next week Nifty bank will bounce back strongly from 21342 support level with expectations of 23000. 3. While is the up move, it will take Axis Bank, ICICI Bank and HDFC Bank along with it as all the stocks are more or less in the same level.
