Time to buy selected stocks

Indexes , again fell today.Sensex fell 2.47% and standing on 13,461.60 and Nifty is on 4040.55.As all say...One should never catch a falling knife.It's time to believe in it.If one is eager to invest at this point of time...one should carefully select the undervalued stocks or the stocks which don't deserve the beating ,what we saw recently.
Indexes are coming down to my given level as i said in my May month blog.My studies say that indexes are near the bottom and it will be wise to buy those stocks ,which are on the supporting level on the charts for a technical bounce which can give the investors 15 to 20 % return in 2 months from now.
