I have drawn here trend line that goes as far as 1993. Nifty now is trading very close to the upper level of that line. Past 2 times when Nifty came touched this line it faced a decent correction. This trend line also gave correct signal to get out before 2007-08 bear rally. Nifty Going above this trend line seems highly unlikely. It is wise to get out before everyone panics & tries to get out. Most Nifty stocks have already corrected, it's just few stocks like Reliance Industries, ITC are supporting Nifty, but how long can this continue. If you ask me it's just a matter of time & you will see Nifty correcting several points from here be careful before going long, just think about the odds of upside to downside from here.
