Nuclear waiver sentiments went off in a Day

There is support at 4200 level which if broken the market will be cheered by Bears and then we will see a rally down .... Rupee is getting weaker and weaker against $ ... for today i think that market will bounce back today against last todays fall but overall the market seems to be bearish. I feel once we complete the rally downwards then there we would bottom out and then only we will take the fresh ride.
