If we go by the predictions about global stock markets prevailing in market, then a correction in Indian stock markets is bound to happen next month...it's a rumor though but who knows if the prediction comes true.
If we see some correction in indian stock markets(while it follow it's global peers) or the second dip in global markets (
read full) next month(as the prediction goes) then Sensex might come at levels of 15000 to 16000. Which looks the correct valuation of Indian markets looking at economic conditions presently.
Then RIL should be the worst stock to fell and it would become the best time for longterm investors to invest in correct valued stock after the fall in september 2010.
