With all the positives surrounding sovereign upgrade Nifty
opened around 100 pts
upwards. But intraday fall doesn't look healthy. However support zone
is seen between 10245 and 10285 and there's high chance of a bounce off that area which should take the index to all time high levels. On the other hand we should be wary of crucial support area
between 10135 and 10180, a breach of which would pull down index to much lower levels. But that looks least likely.
