Markets dropped about 1% led by aggressive selling due to interest rate sensitivities and closed on a weak note. Nifty future faced resistance around 5665 and dragged towards its important support level of 5600 while closed below this key level indicating nifty in the weak zone. This bearishness will continue if nifty holds below 5600 and it may be seen trading in the support zone of 5530-5460. On higher side, 5680 is the key resistance level which will stop nifty to move on higher side.
